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.

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.
