Proven Stem Cell Markers and Multiple Applications

More Bang for Your Buck!

Our Stem Cell Markers remain a growth engine for Neuromics. One of the reasons that you would want to check out offerings are that we have selected markers that can be used in multiple applications.

For example, many of our markers can be used for immunostaining assays to confirm your stem cells are expressing the correct proteins and then these calls can further characterized and purified by Flow Cytometry, Here's an example of  one of our Nestins being used for these two applications.
Figures: (A): Nestin is present in both cell lines, . (B) Corresponding validation by immunofluorescence analysis. (C) Quantitation of nestin intracellular antigen detection (n=3). Error bars indicate standard deviation. DOI: 10.1371/journal.pone.0068519 .

Here are Stem Cell Markers that are designed for Multiple Applications. If you can cover your required applications with one antibody, the net results is a big cost savings!

3-D Screens Predict Breast Cancer Metastasis

Cell-ECM Interactions

3-D culturing solutions and methods are increasingly being used to created more in vivo like assays.

Here researchers use our Human Collagen IV extracellular matrix protein (ECM) to develop a simple biomaterial platform with systematic control over the ECM protein density and composition to determine if integrin binding governs how metastatic cells differentiate between secondary tissue sites: L.E. Barney, E.C. Dandley, L.E. Jansen, N.G. Reich, A.M. Mercurio, and S.R. Peyton. A cell–ECM screening method to predict breast cancer metastasis. Integr Biol (Camb). 2015 Feb 10; 7(2): 198–212. doi: 10.1039/c4ib00218k.

This publication details the creation of an in vitro fingerprint that is predictive of in vivo metastasis.

Figure: Biomaterial platform for integrin-mediated phenotyping. (a) Breast cancer cell lines with their known in vivo metastatic tropisms.  (b) Three distinct ECM microenvironments regulate integrin binding. (c) Adhesion and motility phenotypes of the MDA-MB-231 cell line. Black: ECM 1; blue: ECM 2; green: ECM 3.
Figure: Correlations between adhesion and migration responses identify potent integrin antibodies in vitro. Pairwise comparisons between adhesion and migration measurements in the (a, b) MDA-MB-231 and (c, d) SkBr3 cell lines across normal, EGF-stimulated, and integrin antibody conditions. Arrows highlight conditions where integrin antibodies increased migration metrics. Spearman correlations are indicated on each plot with two-tailed p-values. Circle: ECM 1; square: ECM 2; triangle: ECM 3; black: normal; green: EGF; blue: anti-β1 integrin; red: anti-α2 integrin; orange: anti-α6 integrin. (e, f) SkBr3 migration mechanisms are displayed via 10 random cell paths under (e) normal and (f) anti-β1 conditions. Red paths identify cells detaching and adhering elsewhere on the surface. Inset: representative images of cell morphology. Scale bar is 25 μm. (g) Individual cells that invaded into an overlaid 3D collagen gel from the ECM 1 surface after 48 hours. Bar indicates mean distance invaded of all invading cells. Inset: schematic of cells invading upward from the ECM surface into an overlaid gel.

A richer understanding of cancer metastasis is important for the development of new, more potent chemotherapies. I am hopeful 3-D/ECM assays become more embraced as a way to more accuratly determine in vivo cell behaviors.

Bioactive FGF Basic Recombinant Protein in Action

Maintaining Sheep Mesenchymal Stem Cell Multipotency

We have been very selective in the Bioactive FGF2 or FGF-basic Recombinant Proteins we make available to Stem Cell Researchers. They are many options available so we are always encouraged when we see ours referenced in publications.

Here researchers used our FGF2 to expand Sheep Bone Marrow Stem Cells (BMSCs) in culture: Troy D Bornes, Nadr M Jomha, Aillette Mulet-Sierra and Adetola B Adesida. Hypoxic culture of bone marrow-derived mesenchymal stromal stem cells differentially enhances in vitro chondrogenesis within cell-seeded collagen and hyaluronic acid porous scaffolds.Stem Cell Research & Therapy 2015, 6:84 doi:10.1186/s13287-015-0075-4.

These cells were used for chondrogenesis studies.

Expansion of BMSCs: Bone marrow aspirate collections containing 8 x 107 MNCs were seeded within each 150-cm2 tissue culture flask. Culture medium composed of alpha-minimal essential medium (α-MEM) supplemented with 10% v/v heat-inactivated fetal bovine serum (FBS), penicillinstreptomycin-glutamine, 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), and sodium pyruvate (all from Life Technologies, Burlington, Canada) was pipetted into each flask. Fibroblast growth factor-2 (FGF-2; Neuromics Inc., Edina, USA) was added at a concentration of 5 ng/ml in order to maintain cell multipotency. Nucleated cells were allowed to adhere and grow for seven days before the first media change under normoxia (ambient 21% O2) or hypoxia (low 3% O2) at 37°C in a humidified incubator containing 5% CO2. Flasks from the hypoxic incubator experienced short periods (less than 5 minutes) of normoxic exposure during media changes. Thereafter, the media were changed twice per week until 80% cell confluence was obtained. Adherent BMSCs were detached using 0.05% w/v trypsin-ethylenediaminetetraacetic acid (EDTA; Sigma-Aldrich Corp., Oakville, Canada) and expanded under the same oxygen tension (normoxia or hypoxia) as during isolation until P2 prior to scaffold seeding. Hereafter for brevity, BMSCs described by expansion oxygen tension alone (normoxia-expanded and hypoxia-expanded BMSCs) will refer to BMSCs that were isolated and expanded under normoxia and hypoxia, respectively. The time taken from plating of nucleated cells (P0) to reach approximately 80% confluence at P2, before experimental use, varied from three to four weeks.

I anticipate more publications on these important bioactive reports as demand for them has been growing.

Markers for Oligodendrocyte Progenitor Cells (OPCs)

Improving OPC Expansion

Researchers reference use of Neuromics' GFAP and PDGF R Alpha/CD140A for OPC Selection

The data provided in this publication demonstrates that the OPC yield from SVZ-derived cell cultures can be improved with the PDGF-BB isoform in comparison to classical bFGF-EGF, or PDGF-AA-based protocols. Additionally, it would be expected that the OPC-enriched cultures obtained from NSC/NPC exposure to PDGF-BB and heparin generate cells suitable for cell transplantation for treating demyelinating diseases: Paula G. Franco, Juana M. Pasquini, Lucas Silvestroff. Optimizing Culture Medium Composition to Improve Oligodendrocyte Progenitor Cell Yields In Vitro from Subventricular Zone-Derived Neural Progenitor Cell Neurospheres. Published: April 2, 2015DOI: 10.1371/journal.pone.0121774:

Images: Detection of OPC markers by ICC on NS cells. A) Quantitation of NG2+ and/or PDGFRα+ cell proportions in WT mice NS generated in the presence of different growth factor combinations. Data belong to three independent experiments for each condition. Data for NG2-/PDGFRα- was analyzed with a One-way ANOVA plus Dunnett´s post test, where bFGF/EGF was set as the control. B, C) Representative images of NG2+ and PDGFRα+ cells generated from WT mice cultures in the presence of either bFGF/EGF or bFGF/PDGF-BB. D) Comparison of NG2+ or PDGFRα+ cell proportions in NS cultures generated from Act::EGFP mice in the presence of bFGF/EGF or bFGF/PDGF-BB. Data for NG2+ (dark magenta) or PDGFRα+ (light magenta) cells was analyzed separately with Student´s t test. E, F) NG2 and PDGFRα immunodetection in CNP::EGFP derived cultures. Gray bars in each graph were analyzed with Student´s t test. G) Olig2 expression in WT mice NS cultures. Asterisks are colour coded to indicate the pairs of bars compared and analyzed with Student´s t test. Cell proportions in A, and D-G are expressed as a fraction of the total cell nuclei counted for each condition. Error bars represent the SD for all bar graphs.. doi:10.1371/journal.pone.0121774.g001.

Neuromics has an excellent catalog of Stem Cell Selection Markers.

The Importance of in vivo Like Astroglial-Neuron Co-Cultures

What We Have Learned

I have many posting on both Neuron and Astroglial Cultures. We have now evolved our solution set to include in vivo like co-cultures. These Astroglial Neuron Co-cultures are designed to mimic in vivo like behaviors. They are potent, pure and proven to work in our clients' unique neurodegenerative disease and toxicity drug discovery assays.
Why is this important? The mix of Astrocytes, Glia and Neurons in your co-cultures can impact your data endpoints and lead to inaccurate conclusions. Here're examples as to how much your data can fluctuate. These are data generated from toxicity assays.
We stand ready to serve you and your team. Questions? Don not hesitate to call 612-801-1007 or e-mail me pshuster@neuromics.com. Pete Shuster, CEO and Owner, Neuromics.

Nestin Expression in Differentiating Neural Progenitors

Breathtaking Images

Our Nestin Antibody + a ​HES5::eGFP reporter was one of the markers used to visualize differentiating stem/progenitor cells (see: Nature Communications 6, Article number: 6500 doi:10.1038/ncomms7500).


Figures: (a) Neural differentiation scheme. Neural induction was performed by a dual SMAD inhibition protocol followed by long-term propagation with the factors indicated for 220 days.

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.

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.
