The Power of ISOkine Stem Cell Growth Factors

What Endotoxin, Animal and Serum Free Means to You

ISOkine™ growth factors are produced in barley, bypassing the use of bacterial or animal cell systems.

Why Does this Matter? Proteins produced in bacterial systems contain trace Endotoxins (toxins produced by the bacterial hosts). Studies show that these Endotoxins can compromise health of your stem cell based assays. Animal and human cell expression systems pose risk to your assays, because they may harbor pathogens.


They are Low Cost and Work in the Hands of our Customers: "The ISOKine mouse LIF is an excellent product! I enjoyed dealing with Neuromics. My interactions with Brett were very professional and he assured me the product was guaranteed to work; which it did." Andy Babwah, Children’s Health Research Institute

Curcumin and Aging Health

Cellular Uptake Matters-Not All Curcumin Based Supplements Are Created Equal

There have been many academic publications on the miracles of Curcumin for Aging Health. Here's a description of its therapeutic properties: The desirable preventive or putative therapeutic properties of curcumin have also been considered to be associated with its antioxidant and anti-inflammatory properties. Because free-radical-mediated peroxidation of membrane lipids and oxidative damage of DNA and proteins are believed to be associated with a variety of chronic pathological complications such as cancer, atherosclerosis, and neurodegenerative diseases, curcumin is thought to play a vital role against these pathological conditions. The anti-inflammatory effect of curcumin is most likely mediated through its ability to inhibit cyclooxygenase-2 (COX-2), lipoxygenase (LOX), and inducible nitric oxide synthase (iNOS). COX-2, LOX, and iNOS are important enzymes that mediate inflammatory processes. Improper upregulation of COX-2 and/or iNOS has been associated with the pathophysiology of certain types of human cancer as well as inflammatory disorders. Because inflammation is closely linked to tumor promotion, curcumin with its potent anti-inflammatory property is anticipated to exert chemopreventive effects on carcinogenesis. Hence, the past few decades have witnessed intense research devoted to the antioxidant and anti-inflammatory properties of curcumin. In this review, we describe both antioxidant and anti-inflammatory properties of curcumin, the mode of action of curcumin, and its therapeutic usage against different pathological conditions see: (Adv Exp Med Biol. 2007;595:105-25).

The Roots of Anxiety Induced Pain

Corticotropin-Releasing Factor and ERK1/2 Pathway

This study crossed my radar scope because the investigators referenced use of our phosphoERK1/2 for Western Blotting and Immunohistochemistry: Gisela Patrícia da Silva Borges , Juan Antonio Micó Segura , Fani Lourença Moreira Neto , Esther Berrocoso. Corticotropin-Releasing Factor Mediates Pain-Induced Anxiety through the ERK1/2 Signaling Cascade in Locus Coeruleus Neurons. DOI: http://dx.doi.org/10.1093/ijnp/pyv019 First published online: 25 February 2015

Conclusion: pain-induced anxiety is mediated by CRF neurotransmission in the LC through ERK1/2 signaling cascade.

Figure: a) Schematic representation of the anatomical pathways implicated. Briefly, the contralateral LC indirectly receives inputs from the inflamed paw (red dashed line; ascending pathways) and, subsequently, the information is sent to corticolimbic areas. Additionally, the LC sends direct projections to the spinal cord (blue straight line; descending pathways). b) Body weight of the control and MA rats. c) Body rectal temperature of control and MA rats. d) Mechanical hyperalgesia represented by a significant decrease in the paw withdrawal threshold of the ipsilateral paw of MA rats. e) Mechanical allodynia represented by a significant decrease in the force threshold of the ipsilateral paw of MA rats. Graph depicting the expression of pERK1/2 in the LC after intra-LC administration of the αCRF receptor antagonist, showing that the significant increase of pERK1/2 in MA4W animals was no longer observed when this antagonist was administered.  g) Graph showing that the local administration of the αCRF antagonist had no significant effect on mechanical hyperalgesia in MA4W rats. h) Graph showing that local administration of h) Graph showing that local administration of the α-helical CRF antagonist had no significant effect on mechanical allodynia in the ipsilateral paw of MA rats. i) Graph showing that the time spent in the open arms decreased in MA4W rats receiving the vehicle alone but this effect was successfully reversed by administration of the αCRF antagonist. j) Graph showing that local administration of the α-helical CRF antagonist had no significant effect on the total distance traveled in the elevated zero maze. k) Graph showing that local administration of the α-helical CRF antagonist reversed the decrease in the number of entries into the open arms observed in MA4W rats receiving the vehicle alone. B=Baseline; LC=Locus Coeruleus; αCRF=antagonist of the corticotropin-releasing factor receptor I and II; W=Week; MA=Monoarthritis.
 

Western Blotting: The membranes were blocked with 5% Bovine Serum Albumin (BSA; Sigma, Spain) in TBST and probed overnight at 4 ºC with a rabbit anti-phospho-ERK1/2 (1:5,000; Neuromics). Immunohistochemistry: Brains were removed and processed for free-floating immunohistochemistry. One in five sequential transverse brain sections (30 µm) containing the PVN from each rat were washed, blocked and incubated with a rabbit antiserum against the phosphorylated ERK1 and ERK2 isoforms (pERK1/2; 1:1000; 48 hours at 4-8ºC: Neuromics, USA). Immunodetection was achieved with a biotinylated donkey anti-rabbit antiserum (1:500; 1 hour; Jackson ImmunoResearch, USA), followed by an ABC solution (1:200, 1 hour; ABC Elite kit, Vector Laboratories, UK) and a colorimetric reaction with 3,3-diaminobenzidine tetrahydrochloride (DAB; 10 min) in 0.05M Tris-HCl buffer containing 0.003% hydrogen peroxide (Cruz et al., 2005). Sections were then washed in PBS, mounted on gelatin-coated glass slides, cleared in xylene, cover-slipped with DPX and analyzed by light microscopy.

We have a broad range of pain and inflammatory response research markers. Check us out today.

i-Fect Delivers siRNA in vitro and in vivo

Gene Expression Analysis for Studying Stroke

We have posted over 35 publications that reference use of our i-Fect Transfection Kit to deliver siRNA, miRNA and shRNA in vitro and in vivo. Results documented in these publications prove that this kit is both non-toxic and delivers ultra-high transfection efficiency.

i-Fect Data Example


Figure. The effects of HDAC2 siRNA Infusion into the CeA of P rats on voluntary ethanol consumption as measured by the two-bottle free choice paradigm. Monitoring the voluntary ethanol consumption of alcohol-preferring (P) rats via the two bottle free choice paradigm following infusion of vehicle or histone deacetylase isoform 2 (HDAC2) siRNA into the central amygdala (CeA) demonstrates that high HDAC2 levels may mediate the high alcohol drinking behaviors of P rats. P rats were given access to water and 7% ethanol followed by water and 9% ethanol. On the sixth day of ethanol access P rats received infusion of vehicle or HDAC2 siRNA and consumption of water and 9% ethanol were monitored for sevnfusion. Total fluid intake did not significantly differ between the groups. Values are represented as the mean ± SEM of the ethanol consumption (g / kg / day) and total fluid intake (mL) plotted daily for n=6 rats per treatment group. *Significantly different between the groups.SACHIN MOONAT. The Role of Amygdaloid Chromatin and Synaptic Remodeling in Anxiety and Alcoholism. THESIS Submitted as partial fulfillment of the requirements for the degree of Doctor of Philosophy in Neuroscience in the Graduate College of the University of Illinois at Chicago, 2014.

Here's yet another recent publication highlighting use of i-Fect:

In this study data suggest the protective effects of EPO on NUV injuries are highly associated with the increase of p-Cx43, which improves GJIC to reduce neurotoxic substances: Ziyi Zhoua, Xiaobai Weib, Jun Xiang, Junpeng Gao, Lixin Wang, Jinsong You, Yefeng Cai , Dingfang Caid. Protection of erythropoietin against ischemic neurovascular unit injuries through the effects of connexin43. Biochemical and Biophysical Research Communications. doi:10.1016/j.bbrc.2015.02...The strands were incubated at 90°C for 5 min and then at 37°C for 1 h. SiRNA was prepared immediately before administration by mixing the RNA solution (1 μg/μl in annealing buffer) with the transfection reagent i-Fect (v/v: 1/3; Neuromics, Edina, MN, USA) to a final siRNA ...

Highlights
•EPO has protective effects on ischemic NVU injuries.
•EPO up-regulates phosphorylation of Cx43, not total Cx43.
•EPO's protective effects on NUV injuries are p-Cx43-GJIC dependent.

Proven and Published Sandwich ELISA Kits

Growing Catalog of ELISA Kits

We are partnering with RayBiotech to manufacture our ELISA Kits. They have proven valuable additions to our Cell Based Assay solutions.

Neuromics has been built on a foundation of quality. RayBiotech's commitment to quality includes compliance to GLP/GMP FDA and ISO9000 regulations.
ELISA Kits Sample Data

Figure: Induction of proinflammatory cytokines is attenuated in CX3CL1−/− mice expressing sFKN. TNFα and IL-1β concentrations were measured using standard ELISA techniques for VM lysates. a, TNFα concentrations were upregulated following MPTP administration (three-way ANOVA; F(1, 23) = 18.36, ★★★p < 0.001). Comparatively, CX3CL1−/− mice expressing sFKN in the SNpc had significantly lower concentrations of TNFα relative to mFKN (Tukey's HSD; ***p < 0.001) and GFP (Tukey's HSD; ###p < 0.001) expressing mice. There were no significant differences between sFKN and WT-MPTP (Tukey's HSD; p = 0.384) or mFKN and GFP (Tukey's HSD; p = 0.773). b, The IL-1β concentrations in the VM were significantly upregulated for mice exposed to MPTP (three-way ANOVA; F(1, 23) = 11.97, ★★★p = 0.002). Similar to the pattern of TNFα, IL-1β concentrations in CX3CL1−/− mice expressing sFKN were significantly blunted compared to both mFKN (Tukey's HSD; ***p = 0.001) and GFP (Tukey's HSD; ###p < 0.001). As was observed with TNFα, there were no significant differences in IL-1β concentrations between WT-MPTP and sFKN (Tukey's HSD; p = 0.785) or mFKN and GFP (Tukey's HSD; p = 0.845) expressing mice. Data are presented as the mean ± SEM.

Neural Progenitors and Cool Science

Titania Nanotubes and Neural Prostheses

I am always on the hunt for the use of our Neural Progenitor Markers in cool and important human health applications. Here our Nestin Antibody is use to access the growth and maintenance of C17.2 neural stem cell line cultured in these nanotubes: Jonathan A. Sorkin, Stephen Hughes, Paulo Soares, Ketul C. Popat. Titania nanotube arrays as interfaces for neural prostheses. Materials Science and Engineering: C Volume 49, 1 April 2015, Pages 735–745. doi:10.1016/j.msec.2015.01.077

Image: Nestin staining eSC Derived hNP1 Human Neural Progenitors. Cells were stained using goat anti-mouse Alexa Fluor 488 secondary antibody (green) (Molecular Probe, A-11001) and counterstained with DAPI (blue).

Abstract: Neural prostheses have become ever more acceptable treatments for many different types of neurological damage and disease. Here we investigate the use of two different morphologies of titania nanotube arrays as interfaces to advance the longevity and effectiveness of these prostheses. The nanotube arrays were characterized for their nanotopography, crystallinity, conductivity, wettability, surface mechanical properties and adsorption of key proteins: fibrinogen, albumin and laminin. The loosely packed nanotube arrays fabricated using a diethylene glycol based electrolyte, contained a higher presence of the anatase crystal phase and were subsequently more conductive. These arrays yielded surfaces with higher wettability and lower modulus than the densely packed nanotube arrays fabricated using water based electrolyte. Further the adhesion, proliferation and differentiation of the C17.2 neural stem cell line was investigated on the nanotube arrays. The proliferation ratio of the cells as well as the level of neuronal differentiation was seen to increase on the loosely packed arrays. The results indicate that loosely packed nanotube arrays similar to the ones produced here with a DEG based electrolyte, may provide a favorable template for growth and maintenance of C17.2 neural stem cell line.

I will continue to how our stem cell solutions are used in cool, new discoveries.

immunoLink Therapies and Treating ASD Children

6-Months of Therapy and Testing Results

I have previously posted our testing and treatment regime for ASD Children. For some of the children, we are seeing marked improvement after 6 months of our treatment regime using solutions aimed at balance immunity and stem cell vitality.

We find that for the children we treat all have varying dysregulated levels of immune/inflammatory response, oxidative stress and growth factor/neurotrophin biomarkers.  We customize treatment plans based on pre-treatment testing results. We then re-test after 6 months to see the level of moderation in these biomarkers/factors. The re-tests are used to show the parents how well these children are responding to treatment and to further adjust plans.

Here I would like to share the results from our more traditional medical testing. These are representative results from one of the Children we are treating.

Your current investment in exercise, healthy diet and supplements are aiming you towards what we call the immunoLink sweet spot. If you have hit the bull’s eye, you would be seeking ways to stay there, because this is where you feel awesomely great and are most productive. If you have never been there, now is the time.

Illness, injury and medical procedures push you from the spot, but if you are near or on it, your recovery will be faster and more complete. The far reaches of the immunoLink Spectrum represent a cold wasteland of misery and despair.

How do we Know These Solutions Work?-Our Clients have autoimmune and degenerative diseases or are seeking peak performance. Prior to customizing their treatment strategies, we measure the levels of immune/inflammatory response, oxidative stress, allergens and stem cell health factors in our Clients' blood serum. The levels of these factors are compared with healthy controls. We then re-test after 6 months of treatments. For many the improvement in health and performance are startling. This is confirmed in the re-tests.
Stem-Kine and StemTrophin are central to our treatment strategies. Stem-Kine boosts the levels of circulating blood stem cells. These cells differentiate into immune factors and red blood cells. This boosts oxygen delivery and immunity resulting in greater endurance, mental acuity and cardiovascular health. StemTrophin activates mesenchymal stem cell migration. These cells are essential for immune suppression and then initiating the process of repair and regeneration at the sites of injury or degeneration.

Treating Autism-Immune System Balancing and Stem Cell Activating Therapies

Linking the Immune System with Stem Cell Health to Treat ASD Children

We have been testing immune/inflammatory response, oxidative stress and growth factor/neurotrophin biomarkers in the blood sera of Children with Autism Spectrum Disorder (ASD). We did this testing using our Quantibody Arrays.

The purpose of these tests were to establish a baseline for the state of these children's immune system and stem cell health. In this baseline testing, we found that all had high immune/inflammatory response, oxidative stress and low levels of the growth factors/neurotrophins needed for repairing and regenerated damaged cells/tissue (stem cell health).

We then treated these children with customized combinations of immune balancing and stem cell activating agents with the goal of showing that any improvement in ASD related symproms would be confirmed by positive modulations of biomarkers that are dysregulated in this disorder. We re-test at 6 months after initiation of the treatment plans.

The goal of our treatment strategies is to balance the immune system and activate the natural cell/tissue repair and regeneration (stem cell) processes. We call this the immunoLinkTM.

We are seeing improvement in the symptoms of the first 2 children recently retested and a marked improvement in the levels of their biomarkers. Here's data from one of the children. Note that key immune/inflammatory response markers have now moderated to the levels of healthy controls.

Graphs: Comparison of initial testing (red) and 6 month re-test (green) vs healthy controls (blue) for one of our ASD Children

We are developing a website that will have a wealth of information to help parents determine treatment strategies for ASD Children. We are also making our treatment plans and strategies available to interested parents. The website ecosystem will be named immunoLinkTM Therapies.
In the meantime, should you want to investigate if we could help your child, do not hesitate to contact me e-mail: pshuster@neuromics.com or cell: 612-801-1007. Pete Shuster, CEO and Owner.

Immune System/Stem Cell Health and Aging

Looking, feeling and  performing your best depends on balanced immunity and stem cell vitality

As we age we encounter:
  • Slower healing
  • Longer recovery time from vigorous exercise
  • More general aches and pains
  • Longer recovery from illness
  • Wrinkled, dry and thinning skin
Why is that? What are the causes? Answers can be found by a better understanding of immune/inflammatory response and stem cell systems. As we age our immune system weakens or becomes dysregulated (autoimmunity) and our stem cell "bank balances" deplete. My friend and world class stem cell therapies expert, Dr. Neil Riordan, gives an excellent description of the process: Your Body’s Stem Cell Bank Account.

To oversimplify, the immune system is responsible for cleansing the body of pathogens, toxins, allergens and damaged tissues/cells. This creates a healthy environment for stem cells to repair and regenerate new, healthy cells and tissue. We call this process the immunoLinkTM.

immunoLink Therapies is a new company of mine slated to launch in the spring of 2015. Our goal is to slow the aging process by offering solutions that balance your immunity and increase your stem cell vitality. Our vanguard product (currently available) is Stem-Kine. It is a blood stem cell booster which increases the level of immune factors and red blood cells in your cardiovascular system. The result is faster healing/recovery and increased endurance via better oxygen delivery.

100% Serum-Xeno Free Media for Expanding hMSCs

Works as well as our Serum Containing Media

 Selection of Growth and Differentaition media for Mesenechymal Stem Cell Assays is important for the ultimate performance of your cell based assays. The better the media the better the cutures & the lower your costs.



Images: Human mesenchymal stem cells (Catalog no. SC00A1) were plated at 5,000/cm² in a Falcon BD TC-coated T-25 flasks and maintained in serum containing media (Cat. No. SC00B1) and serum-free/xeno-free media (Cat. No. SC00B3) in reduced O2 environment (1% O2, 5% CO2, 90% N2) at 37°C in a humidified chamber. When cells became 80-90% confluent, they were subcultured, counted on a Beckermen Z2 particle counter (range 10-30uM), and passaged. Doubling time of 20-25hrs were calculated in each pass using ln(2*dT)/ln(Cf/Ci), where dT is the time, in hours, from inoculation to detachment; Ci is the initial number of cells plated and Cf is the final number of cells recovered from subculture. There were no apparent differences in doubling time with TC-coated flasks and Laminin/Fibronectin treated flasks.

Testimonial: “We tested the effects of MSCGroTM defined medium using several different lots of human adult primary stem cells and found that MSCGro supports a more robust proliferation rate than normal undefined media. This provided shorter doubling times and increased cellular yield, and maintained the cells in an undifferentiated state. We also found that MSCGro medium is stable under normal laboratory conditions for an extended time period compared to other defined media.” Ben Buehrer, VP and CSO, Zen-Bio

Neurite Outgrowth Assays

Cells, Media and Markers

I have previously posted use of our Neurons in Live Content Assays for the study of Neurite Outgrowth: Neurons-Live Content Assays. These assays are critical for the study of repair and regeneration.

A recent publication featured several of our Neuron MarkersSerena Quarta, Bastian E. Baeumer, Nadja Scherbakov1, Manfred Andratsch, Stefan Rose-John, Georg Dechant3, Christine E. Bandtlow, and Michaela Kress: Peripheral Nerve Regeneration and NGF-Dependent Neurite Outgrowth of Adult Sensory Neurons Converge on STAT3 Phosphorylation Downstream of Neuropoietic Cytokine Receptor gp130. The Journal of Neuroscience, 24 September 2014, 34(39): 13222-13233; doi: 10.1523/JNEUROSCI.1209-13.2014.
Live labeling of neuron cultures: After 20 or 48 h, neurons were live-labeled with α-gp130 antibody diluted in cold TNB medium for 30 min on ice. After washing, neurons were incubated with the secondary antibody diluted in cold TNB medium for 30 min and washed with PBS. Cells were fixed either with 4% PFA for 20 min at room temperature (RT) or with methanol at −20°C for 2 min. After permeabilization with 0.01% TX-100 (Pierce) unspecific binding was blocked for 30 min with 10% normal goat serum (Sigma-Aldrich) in PBS. Cells were incubated with the first antibody for 1 h, washed three times for 10 min with PBS and incubated with the appropriate secondary antibody for 30 min, counterstained with 4′, 6-diamidino-2-phenylindole (1:10,000; Sigma-Aldrich) and embedded in Mowiol (Calbiochem). As primary antibodies, α-gp130 (1:50; Neuromics), α-β-III-tubulin clone TuJ-1 (1:1000; R&D Systems), and α-neurofilament-H (α-NF-H; 1:200; Neuromics) were used. Secondary antibodies used were α-goat AlexaFluor 594 (1:1000; Invitrogen), chicken α-mouse AlexaFluor 594 or donkey α-mouse AlexaFluor 488 (1:1000; Invitrogen), and goat α-chicken AlexaFluor 568 (1:10,000; Invitrogen) for fluorescence microcopy.
