STEMEZ hNeural Progenitors and Cell Migration

I first featured Dr. Steve Stice in August 2008. I have since done follow up posts based on the excellent studies they have been conducting using our  STEMEZ (TM) Human Neural Progenitor & Neuron Discovery Kits.

I would like to highlight a poster based on research Steve and his Team conducted with Platypus Technologies.

Allan C. Powe, Jr., Kathryn L. Hodges, Jamie M. Chilton, Scott Gehler, Renee L. Herber, Keren I. Hulkower, Steven L. Stice. Identification of stimulators and inhibitors of cell migration in human embryonic stem cell derived neural progenitors using a novel, high throughput amenable assay platform.

Investigates the migratory behavior of an adherent monolayer neural progenitor cell line derived from human embryonic stem cells (hNP1 ™; ArunA Biomedical)using a novel 96‐well based cell migration assay platform (Oris™ Cell Migration Assay; Platypus Technologies) amenable for high throughput screening. The assay platform uses stoppers to create central exclusion zones within the wells; cells are plated outside the zone and migrate inward once the stopper is removed.

Data suggest this is a tool for understanding proper nervous system development, development of therapies for cell migration defects, and identifying novel environmental neurotoxicants.

Conclusions:
—The hNP1™ Oris™ Cell Migration Assay can quantitatively detect both stimulators and inhibitors of cell migration.
—Method development to date indicates that the assay has the potential for adaptation as a homogenous HTS‐suitable cell‐based assay.
—Preliminary results suggest that bFGF alone has a potent chemokinetic effect while LIF and GDNF act synergistically to drive migratory behavior during dopaminergic differentiation.
