Musculoskeletal Disorders-Stem Cell Based Drug Discovery

A common Neuromics’ theme is harnessing the power of cellsTM. The raw cost of the cells are often the biggest consideration. We encourage our customers to focus on true costs. These include the # of cells (how many times can they be passaged?), culture viability (how long do the cells live) and bioactivity (how closely do cultures mimic in vivo behavior?). I would like to present a presentation and publication confirming our competitive advantage when analyzing true costs.

Setting a higher bar for Neuron-Glial Based Assays!

Dr. Randen Patterson and his team at UC Davis have developed new culturing techniques using our e18 Rat Primary Hippocampal Neurons. They have developed a protocol that allows for culturing of E18 hippocampal neurons at high densities for more than 120 days. These cultured hippocampal neurons are (i) well differentiated with high numbers of synapses, (ii) anchored securely to their substrate, (iii) have high levels of functional connectivity, and (iv) form dense multi-layered cellular networks. We propose that our culture methodology is likely to be effective for multiple neuronal subtypes–particularly those that can be grown in Neurobasal/B27 media. This methodology presents new avenues for long-term functional studies in neurons. This is good news indeed: Todd GK, Boosalis CA, Burzycki AA, Steinman MQ, Hester LD, et al. (2013) Towards Neuronal Organoids: A Method for Long-Term Culturing of High-Density Hippocampal Neurons. PLoS ONE 8(4): e58996. doi:10.1371/journal.pone.0058996.

We will continue to raise the bar. Better cultures=lower costs and better outcomes!

hN2 Human Neurons & hNP1 Neural Progenitors in Action

I have been promoting Dr. Steve Stice and his team. They are the brains behind our  hN2TM Human Neuron and hNP1TM Human Neural Progenitor Discovery Kits. I would like to share 2 recent publication referencing use of these discovery kits. These validate the postings on capabilities. They are the best solutions available for researchers searching for Neuron or Neural Progenitor Based Assays for basic research, toxicology studies or drug discovery.

Xiugong Gao, Hsiuling Lin, Radharaman Ray, Prabhati Ray. Toxicogenomic Studies of Human Neural Cells Following Exposure to Organophosphorus Chemical Warfare Nerve Agent VX. Neurochemical Research. February 2013…Human hN2 neurons were obtained from Neuromics…

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.

Protocol: Human hN2 neural cellswere obtained from Neuromics (Edina, MN). The hN2 cells were fully differentiated

normal human neural cells derived as adherent cells from human embryonic stem cell (hESC) WA09 line [34] and thus are considered as ‘‘matured’’ neuronal cells. It should
be noted that the universal neural cell marker Tuj (beta tubulin III) indicates that [80 % of the hN2 cells are neural. The other cell types which constitute\20 % of the cell population are mostly astrocytes and microglia, which are common glial cells found in the brain and spinal cord. The inclusion of the small amount of glial cells in the cell population better mimics real life situation in the central nervous system. The hN2 cells were seeded in 12-well plates at *500,000 cells/well in the AB2 Basal Medium complemented with ANS Supplement (cholinesterase free) provided by Neuromics and cultured at 37OC under
humidified 5 % CO2 for 48 h (without changing media) before VX exposure.

Biomaterials, In Press, Corrected Proof,Mar 2013.doi:10.1016/j.biomaterials.2013.02.061 ...hNP1, were obtained from Neuromics (Edina, Minnesota)…

Abstract: Although sensory neurons constitute a critical component for the proper function of the nervous system, the in vitro differentiation of functional sensory neurons from human stem cells has not yet been reported. This study presents the differentiation of sensory neurons (SNs) from a human neural progenitor cell line, hNP1, and their functional maturation in a defined, in vitro culture system without murine cell feeder layers. The SNs were characterized by immunocytochemistry and their functional maturation was evaluated by electrophysiology. Neural crest (NC) precursors, as one of the cellular derivatives in the differentiation culture, were isolated, propagated, and tested for their ability to generate sensory neurons. The hSC-derived SNs, as well as the NC precursors provide valuable tools for developing in vitro functional systems that model sensory neuron-related neural circuits and for designing therapeutic models for related diseases.

Claudia Zylberberg-Cell Culturing Innovator

Taking You Cultures to New Dimensions

I am pleased to feature Dr. Claudia Zylberberg, President and CEO of Akron Biotech, in this edition of “News Behind the News”.  She is an expert and innovator in providing tools and methods for the discovery and development of cell based therapies.  This starts with potent cell based assays and culminates with the ability to provide GMP produced reagents to support animal testing and other pre-clinical trial drug discovery processes.

Scientist and Entrepreneur a Synopsis

Claudia has a background that uniquely positions her to understand and address the growing needs and requirements of the basic and drug discovery research community. This includes researchers using stem cells as for discovery and potential therapies. Here’s an overview.

With a PhD in Biotechnology from the University of British Columbia and University of Buenos Aires, Claudia has over 25 years of experience in the international biopharmaceutical industry.  At NABI Biopharmaceuticals, she and her team developed and scaled plasma-derived products and recombinant vaccines. This included harmonizing products between EMEA and FDA. She has authored and co-authored many scientific articles and developed several commercial products for use in the field of cellular biology. She has also authored a children’s book on genetics and has several patent pending products in the area of cryopreservation and QC of stem cells.

She is as an advisor for the US Pharmacopoeia in standards setting for biologics and ancillary materials critical for the production of cellular therapies.  She is a member of the BioFlorida Board of Directors, Board member of Business Development Board of Palm Beach County, Scientific Advisor for ISCT (International Society for Cell Therapy), Executive Committee Member for the Alliance of Regenerative Medicine and the Chair of the Business Advisory Board for the Banner Center of the State of Florida and is part of the organizing committee for the World Stem Cell Summit coming up in Palm Beach December 2012.

Excellence in Cell Based Assays

Excellent in cell based assays means lower research and development costs. There are two sides of the “cost coin”. On one side, if any of the raw materials (plates, cells, media, growth factors, markers, probes or detection, etc. are a weak link), the whole chain is destroyed and all time and material cost are wasted. On the other side, if culture conditions do not promote an environment enables in vivo like conditions, the data may prove to be unsupported in pre-clinical testing. This results in big costs in both opportunity and related expenses.

This is why Akron Biotech’s product and expertise are so important.  This is also why they could become important partners for Neuromics.  They have the ability to deliver a large cross section of the capabilities required for excellence in cell based assays. 

These capabilities include:

  • Best manufacturing practices (GMP) guarantee products will work as expected.
  • Delivery of tools and methods that support research from the bench to pre-clinical studies.
  • Product strategies that insure current and future fill known gaps in driving cell based assay excellence.

These includes:  media, growth factors, 2D/3-D culturing ECMS and Polyfibers, recombinant proteins and cryopreservatives.  Many fit hand in glove with my strategic offerings. I plan on continue to publishing update on new developments from Akron Biotech.

Inflammatory Macrophages in ALS Spinal Cord

In my many conversation with Neuro-disease researchers, I often learn of discoveries that beg to be shared. I have been collaborating with Dr. Milan Fiala to explore how our hN2 Primary Human Neurons could be best used to study the role of inflammatory cytokines in amyotrophic lateral sclerosis (ALS). This would build on the excellent research he and his team are conducting at UCLA.

He shared with me that these inflammatory cytokines could be the bad actors in ALS. Specifically, in vitro, superoxide dismutase-1 (SOD-1) stimulates expression of inflammatory cytokines, including IL-1β, IL-6, and TNF-α, through activation of cyclooxygenase-2 (COX-2) and caspase-1. Further, they have discovered The lipid mediator resolvin D1 (RvD1) inhibited IL-6 and TNF-α production in ALS macrophages with 1,100 times greater potency than its parent molecule docosahexaenoic acid. ALS peripheral blood mononuclear cells (PBMCs) showed increased transcription of inflammatory cytokines and chemokines at baseline and after stimulation by aggregated wild-type SOD-1, and these cytokines were down regulated by RvD1. Thus the neurons are impacted by macrophages expressing inflammatory cytokines. RvD1 strongly inhibits in ALS macrophages and PBMCs cytokine transcription and production. Resolvins offer a new approach to suppression of inflammatory activation in ALS. To learn more see: Guanghao Liu, Milan Fiala, Mathew T. Mizwicki, James Sayre, Larry Magpantay, Avi Siani, Michelle Mahanian, Madhuri Chattopadhyay, Antonio La Cava, and Martina Wiedau-Pazos. Neuronal phagocytosis by inflammatory macrophages in ALS spinal cord: inhibition of inflammation by resolvin D1.

Furthermore, both Vitro Biopharma and Neuromics are evaluating additional products that are perceived to enhance the competitive advantage of Vitro Biopharma’s existing MSC product line through strategic combination. A strategic goal moving forward, is an additional partner to supply devices needed for FDA-compliant manufacture of clinical materials for use in pre-clinical and clinical studies. These devices are known as bio-reactors that allow for highly controlled and reproducible production of large numbers of stem cells needed to provide therapeutic benefit. Several characteristics of these bioreactors are essential in reaching the demanding goals needed to achieve regulatory compliant manufacturing to support stem cell therapy that maintains rigorous standards of safety and efficacy. We are presently evaluating suitable devices for this application that appear to be well-suited to the required needs, specifications and characteristics.

Dr. Jim Musick, Vitro’s President & CEO, said, “We are very pleased to expand our relationship with Neuromics, Inc and look forward to a long-term mutually beneficial business relationship. While we focus on product development, manufacturing and advancement of our product pipeline, our sales partnerships are important alliances in the expansion of revenue generation. Neuromics is an ideally suited sales partner due to their broad experience and success in distribution of critical life science products. We also see the importance of a complete manufacturing system to support stem cell-based cellular therapy. It is through the highly complex interactions of cells, cell culture media, extracellular matrices and other environmental conditions that together determine the characteristics of the stem cells intended for clinical use. We also anticipate additional expansion of our relationship with Neuromics as Vitro Biopharma’s product pipeline advances through the commercialization process.”

“Neuromics’ strategic direction aligns tightly with Vitro’s goal of ‘Harnessing the Power of Cells™’”, said Shuster, “expanding capabilities enable us to serve an increasing segment of the Biotech and Pharma research community. This is especially true of the stem cell and regenerative medicine research community. Our relationship with Vitro Biopharma adds horsepower to these capabilities. Mesenchymal Stem Cells and Media are raw materials for high throughput and high content cell-based assays. Better materials help insure only the best targets, biologicals and compounds are passed on to downstream processes.”
