Dr. Steve Stice to Present the Power of StemEZ Neural Cells

STEMEZ hN2 Primary Human Neurons

STEMEZ hN2 Primary Human Neurons

I have profiled Steve Stice’s research here. The focus has been the excellent research results he and his team at ArunA Biomedical have generated with STEMEZ(TM) hN2 Human Neurons and hNP1 Human Neural Progenitors.

The story continues. He will be presenting the latest at the 9th Annual World Pharmaceutical Congress in Philadelphia, June 14. Topics include: using these neural cell lines to study neurotoxicity in cell-based assays and disease modeling.  Recent work conducted in outside laboratories demonstrates that these lines are more sensitive to environmental toxicants than traditional cellular models.

Sample high throughput assay applications:

  • Cell morphology and neurite outgrowth
  • Cell signaling and transcription factor expression
  • Receptor and ion channel function
  • Cytotoxicity
  • Apoptosis, genotoxicity and DNA damage

These capabilities has been confirmed by our customers. I look for the use of the STEMEZ cell lines to continue to grow as researchers discover their value in Drug Discovery and Basic Neuroscience capabilities.

STEMEZ hN2 Human Neurons Data

I have been working with Dr. Steve Stice and Aruna Biomedical to deliver human stem and neural cells to identified niche research areas related to drug discovery.  Neuromics rolled out STEMEZTM hN2 Human Neurons Discovery Kits several months ago. Applications for these include: cellular model studies, high content screening, developmental studies, RNAi studies and genetic manipulation.

Drilling down further, I am pleased to present Electro-physiology and related data generated by Aruna and collaborators: hN2 Cells-Electro Phys Data Supplement

 

hN2-Whole Cell Voltage Clamp

hN2-Whole Cell Voltage Clamp

Figure. hN2 cells can produce inward currents that generate action potentials. (A) Isolated hN2 with significant neurite growth 1 week  after plating . This cell was subjected to whole cell voltage clamp utilizing a potassium gluconate based intracellular solution. (B) Voltage gated inward and outward currents were elicited from this cell with depolarizing voltage steps. (C) Inward currents from another cell (potassium gluconate intracellular) were abolished by local application of 1 µM tetrodotoxin (red trace) while outward currents remained. Inward current recovered as TTX washed out of the region (green trace). (D) A different cell which exhibited voltage activated inward currents that inactivated in response to a 50 ms prepulse at different membrane potentials. The experiment was done 27 days after the removal of bFGF. A cesium gluconate based intracellular solution was used for this experiment to block outward potassium currents. The membrane potential for half maximal inactivation by standard Boltzman fitting (red line) was -40.1 mV with a slope of 4.7. (E) Recovery from fast inactivation utilizing a paired pulse protocol in the same cell as C. The single exponential time constant for recovery of inactivation was 1.7 ms (red line). (F) A different cell which elicited an overshooting action potential upon current injection under whole cell current clamp utilizing a potassium gluconate based intracellular solution. Inset: Response of the same cell under voltage clamp to a change in membrane potential from -80 mV to -10 mV elicited a peak current of 457 pA. Scale bars for inset: 5 ms, 0.2 nA.

Steve Stice-The Professor Entrepreneur

Dr Steve Stice and Human Stem Cells

I am pleased and honored for the privilege of profiling Dr. Steve Stice.  He has a history of working in areas that are Biotechnology Headliners…from cloning to stem cells. Here I will be focusing on his current work with Human Stem Cells and Neural Progenitors  at ArunA Biomedical and The University of Georgia. As with all the News Behind the Neuroscience News, I will highlight how it could impact Neuroscience Research and Drug Discovery.

The Back Story

Where it Starts

Steve embodies a rare blend of entrepreneurship and scientific curiosity. He has been referred to in the press as “part professor; part entrepreneur”. This uniquely positions Steve to take his inventions from the lab directly to the marketplace by forming Biotechnology Companies. The DNA for ArunA comes from several of his earlier start-ups: Advanced Cell Technology and Cytogenesis (now part of BresaGen).

About Dr. Steve Stice

Dr. Steve Stice is CSO of Aruna Biomedical Inc and a Professor and Director of the Regenerative Bioscience Center and has a Georgia Research Alliance Eminent Scholar endowed chair.

 

Prior to joining the University of Georgia, Dr. Stice was a cofounder and Chief Scientific Officer at Advanced Cell Technology, a stem cell company.  Throughout his career he has published and lectured internationally on the topics of cloning and stem cells. 

 

In 2001, three of the human embryonic stem cell lines that Dr Stice’s lab derived were approved for federal funding by President Bush. In 2006, he was appointed by Gov. Perdue to the Post Natal Cord Blood Commission for the state of Georgia.

 

Dr. Stice founded Aruna Biomedical, Inc., and in cooperation with Millipore Inc. was first group to market a product derived from human embryonic stem cells (2007). The product is a neural stem cell used for research on neurological diseases and disorders, ranging from Parkinson’s disease to depression.

As co-founder and CSO of Advanced Cell Technology, he has helped commercialize discovery platforms that could enable the application of stem cell technologies to the field of regenerative medicine to bring effective therapies to patients suffering from degenerative diseases like age-related macular degeneration. The company recently passed the milestone of  successfully. restoring visual function in rats through the implantation of RPE cells derived from human embryonic stem cells and in early 2008, completed pre-IND meetings with the FDA. Yes, Human Stem Cell based therapies have the potential to make the blind  see.

This bring us to ArunA. I am excited about their current and future products because their is a pent up need for them by the Neuroscience Research community which includes many of Neuromics’ Customers.

The ArunA Biomedical Story
Steve started ArunA in 2003. It actually sprung from a frustrating aspect of using Stem Cells for research. They are infinitely useful but hard to grow in cultures and differentiate into the research required cell types. Steve became acutely aware of this from his work starting in 2001 including a 5 day course he taught at NIH. Steve understood that most researchers do not want to spend the time and related frustrations associated with  this exercise. It is kind of like building a computer so you could enjoy the benefits of the web. In other words, Neuroscientists could care less about undifferentiated stem cells. At the very least, they want pure and healthy Neural Progenitors. These can then be expanded and differentiated into specific neurons. For example an ALS Researcher would be interested in making Motor Neurons; a Parkinson’s Researcher, Dopamanergic Neurons and a Pain Researcher, GABAmanergic. Nirvana for these researchers would be having pure cultures of these Neuron types at their fingertips.

Current Products

There is good news. Neuroscientists can now easily and inexpensively get human neural progenitor cells for Drug Discovery, Toxicity and Basic Research.

ENStem-A ™, Neural Progenitor Expansion Kit
hN2™, ArunA Human Neural Cell Kit 

So what was once difficult and frustrating, is now easy and convenient. Buy the kits and here’s an example of what you get.

What is Next

Knowing the needs and wants of the marketplace, ArunA’s products and capabilities excite me. Any tools that have they capabilities to bring researchers a steps closer to discovering cures for insidious Neuro-diseases need to be embraced. All of us have or will be touched by these diseases.

In my conversations with Steve, I am impressed with his clear understanding of how to evolve ArunA’s product to increase their value proposition. Available soon could be cultures developed to fit the niche needs of specific researrch areas like Parkinson’s, Pain’s and Alzheimer’s. I plan on communicating these evolutions here and at my company’s website @ www.neuromics.com.

On Deck-Dr. Steve Stice

We read about the promise of stem cells in the news every day. They could prove to be “magic bullets” for curing diseases like Alzheimer’s. Parkinson’s, MS and others. Stem Cell Research is also surrounded with controversy as currently cells are often harvested from human embryos and fetuses.I believe top researchers will prove to be the voice of reason in the human stem cell debate as they are the ones best positioned to know the risks, limitations and potential.  

For our August Profile, I am honored to be featuring Dr. Steve Stice. I have had the pleasure of working with Dr. Stice both in his role as Professor and Director of the Regenerative Bioscience Center and Research Alliance Eminent Scholar endowed Chair at the University of Georgia and as Founder and Chief Scientific Officer at Aruna Biomedical.

He has over 16 years of research and development experience in biotechnology and is a co-founder of five biotechnology companies.  He was named one of the 100 Most Influential Georgians by Georgia Trend magazine.  He produced the first cloned rabbit in 1987 and the first cloned transgenic calves in 1998 (George and Charlie).  In 1997 his group produced the first genetically modified embryonic stem cell derived pigs and cattle.  This research led to publications in Science and Nature journals, national news coverage (CBS, NBC, ABC and CNN) and the first US patents on cloning animals and cattle embryonic stem cells.  In 2001, Dr. Stice announced the first cloned animal (calf) from an animal that was dead for 48 hours.  In 2005, his stem cell group published the first work on deriving motor neurons from stem cells.  Motor neurons are damaged lost during the progression of several diseases such as ALS and spinal muscular atrophy.  Throughout his career he has published and lectured on cloning and stem cell technologies.  Prior to joining the University of Georgia, Dr. Stice was a co-founder and Chief Scientific Officer at Advanced Cell Technology, a company developing cloning and stem cell technology.

Here is What is  Currently Hot in the Stice Lab:
New neural stem cells technology developed in my lab was transferred to a commercial entity, Aruna biomedical. This is the first commercialized product derived from human embryonic stem cell using federally approved stem cell lines.

  • We have produced neurons that have neural functions
  • We are working with the Navy to use our neural cells as biosensors for environmental toxins 
  • We have vascular stem cells that have characteristics that may make them suitable for  transplantation
  • We collaborate with a new company call Aruna BioMedical  that will stem cells for neural research and drug discovery
  • Developed a method to test new compounds for Alzheimer’s disease using our neural stem cell
  • We are one of five NIH stem cell training centers and have taught Scientists from Georgia to Bombay India new stem cell techniques
  • In Georgia, we produced over 50 cloned calves and 100 cloned pigs.
  • We were also the first to produce a clone from an animal that had been dead for 48 hours. This opens new opportunities in agriculture and preserving endangered species.
