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.

hN2 Primary Human Neurons and Toxicity Assays

Neuromics' hN2 Cells Continue to Shine

I previously posted our Human hN2 Neurons being used for studying the mechanisms of  Nerve Agent VX: hN2 Human Neurons for Toxicity Screening. The versatility of these neurons enabled the researchers to perform a microarray study in which cultured human neural cells were exposed to 0.1 or 10 μM of VX for 1 h. Global gene expression changes were analyzed 6, 24, and 72 h post exposure. Solid primary cell based assay results start with healthy and well behaving cells.

I am pleased to announce success in exposing the cells to a specific cytotoxicity inducing compound (small molecule): Mark RichardsChee Wee PhoonGwendoline Tze Wei GohEng Khuan SengXu Ming GuoCherine Mei Fong TanWoon-Khiong ChanJoel Mun Kin Lee. A New Class of Pluripotent Stem Cell Cytotoxic Small Molecules. Research Article | published 19 Mar 2014 | PLOS ONE 10.1371/journal.pone.0085039.

Image: Cytotoxic agent used in dose-response curve

Figure: Dose response curves for 3 specialized somatic cell lines (MRC-5, human primary neurons and human neonatal cardiomyocytes) treated with JC011.

This curve illustrates the sensitivity of human neurons to toxic agents. 

We plan on continuing to use these and our hNP1 Human Neural Progenitors in kinetic, "in vivo like" assays. These assays will give quantitative data on both growth and differentiation inducing agents as well as specifics on how the cells behave when exposed to toxic agents. I will be posting results here.

This data should be of interested to neuro-disease/disorders basic and drug discovery researchers. We plan on making the assays available to researchers. We currently also do small molecule testing and gene expression analysis studies a CRO offering. To learn more, I can be reached at pshuster@neuromics.com or 612-801-1007.

Autism, Inflammation and Stem Cell Enhancers

Proving the Therapeutic Value

We have been running Quantibody® Antibody Arrays on blood serum of children diagnosed with Autism Spectrum Disorder (ASD). All reside in areas of heavy industry in Central Europe. All have elevated levels of one or several heavy metals.

These assays are being run as part of our strategy of treating these children with natural stem cell enhancing supplements. Here are the average serum levels of 2 cytokines (IL-6 and TNF-alpha) and 1 related chemokine (CCL3). All of the children had elevated levels vs healthy controls:

Figure: Serum ASD levels vs Healthy Controls (pg/ml)

TNF-alpha and IL-6 promotes the immune/inflammatory response. These two cytokines are guided to sites (including the CNS) of infection or tissue damage by the chemokine CCL-3 and others. In the normal process, the site(s) of immune response are cleaned (the response) of infection and/or damaged tissue and then repaired. The key with autoimmune diseases and disorders, is that that this process becomes a continuous loop; hence, these cytokines and chemokines are elevated. If the loop is broken or down modulated, the the levels of these should decrease.

Mesenchymal stem cells (MSCs) are immunomodulating and anti-inflammatory. We plan on testing candidate substances (all our currently available as natural supplements) on kinetic assays using our umbilical cord blood human mesenchymal stem cells. These will enable us to quantify  cell growth and expansion. We also plan on testing the best candidates on our human neurons to see the effects on cell behavior.

We will then determine safe dosing working with experts in the U.S. and Europe. During treatment, we will again be testing serum to see if the levels of these and other key Cytokines, Chemokines and Growth Factors. This will give proof as to to whether or not the treatments are working. If so, we should see the serum levels of these move toward to those of healthy controls.

I plan on making more data as it becomes available.

hN2 Human Neurons for Toxicity Screening

Our Human hN2 Neurons proving excellent platforms for Neurotoxicology Studies. I would like to share recent publication and that confirms the potential of these solutions for use in your toxicology assays.

Abstract: Organophosphorus (OP) compounds represent an important group of chemical warfare nerve agents that remains a significant and constant military and civilian threat. OP compounds are considered acting primarily via cholinergic pathways by binding irreversibly to acetylcholinesterase, an important regulator of the neurotransmitter acetylcholine. Many studies over the past years have suggested that other mechanisms of OP toxicity exist, which need to be unraveled by a comprehensive and systematic approach such as genome-wide gene expression analysis. Here we performed a microarray study in which cultured human neural cells were exposed to 0.1 or 10 μM of VX for 1 h. Global gene expression changes were analyzed 6, 24, and 72 h post exposure. Functional annotation and pathway analysis of the differentially expressed genes has revealed many genes, networks and canonical pathways that are related to nervous system development and function, or to neurodegenerative diseases such as Alzheimer’s disease, Huntington’s disease, and Parkinson’s disease. In particular, the neuregulin pathway impacted by VX exposure has important implications in many nervous system diseases including schizophrenia. These results provide useful information valuable in developing suitable antidotes for more effective prevention and treatment of, as well as in developing biomarkers for, VX-induced chronic neurotoxicity.

Image: hN2 cells grown in culture for 4 days and stained with our chicken polyclonal to Neurofilament light or low molecular weight chain NF-L, a marker of neurons. Many of the differentiating cells show strong cytoplasmic and clearly fibrillar staining for NF-L. Blue stain is DAPI and reveals cell nuclei of some non neuronal cells in this culture

I will continue to post updates on new applications of these potent, pure and easy to grow human neurons.

Primary Neuron Assays for Studying Neurodegeneration

Our goal is to provide our customers and collaborators the tools they need to insure success. This is defined by having the specific Primary Neurons, Growth Factor plus the Markers to meet unique research needs.

The proof is in the results. Here are some highlights.
Images/Data: FIGURE 5. Microglial p38α MAPK-dependent TNFα is involved in LPS-induced neurite degeneration. (A) Photomicrographs of MAP-2 immunocytochemistry show the morphology of neurons after 72h of co-culture with microglia. The arrow points to the appearance of neurites that have been damaged by LPS-activated WT microglia. In contrast, the arrowhead points to the morphological appearance of healthy, undamaged neurites. (B) Diagram of the Sholl method for quantifying the total number of healthy neurites that intersect the concentric circles. (C) Quantification of healthy neurites by the Sholl analysis demonstrates that LPS stimulation of p38α WT microglia in co-culture causes neurite degeneration as seen by a significant reduction in the number of intersections by healthy neurites in the LPS-stimulated group compared to the unstimulated group (white bars). This degeneration can be attenuated by the addition of a blocking antibody to TNFα (5μg/ml), while the non-immune IgG control was not protective (gray bars). Microglia from p38α KO mice stimulated with LPS (black bar) also have significantly less neurite degeneration than the LPS-stimulated p38α WT microglia (white bar). However, by adding TNFα back to the p38α KO microglia co-culture, there is a significant decrease in the healthy neurite arborization compared to the p38α KO microglia stimulated with LPS alone (black bars). (***p<0.005; Bonferroni’s multiple comparison test). Data represents 2 independent experiments. Scale bar equals 25μm. Molecular Neurodegeneration 2011, 6:84 doi:10.1186/1750-1326-6-84
hN2 cells grown in culture for 4 days and stained with our chicken polyclonal to Neurofilament light or low molecular weight chain NF-L, a marker of neurons. Many of the differentiating cells show strong cytoplasmic and clearly fibrillar staining for NF-L. Blue stain is DAPI and reveals cell nuclei of some non neuronal cells in this culture.

We will continue to post relevant images and data that demonstrate our capabilities.
