The presence of platelet-derived growth factor AA homodimer (PDGF-AA) and basic fibroblast growth factor (bFGF) in complete GPC growth medium allows rat GPCs to remain undifferentiated.  Figure 1 shows more than 80% of the GPC population retain the undifferentiated phenotypic marker A2B5.


Figure 1.  Rat GPCs stained by indirect immunofluorescence for the cell-surface marker A2B5 (green).  Nuclei were stained with DAPI (blue).  Cells were maintained in the undifferentiated state in GPC recovery media for three days prior to 4% paraformaldehyde fixation and staining.

Upon expansion, rat GPCs retain their differentiation potential into oligodendrocytes and astrocytes.  Figure 2 shows rat GPCs differentiating into oligodendroctes. More than 30% of rat GPCs were stained positive for GalC (oligodendrocyte specific marker).
 Figure 2.  Rat GPCs differentiating to oligodendrocytes.  The cells were differentiated in growth medium lacking PDGF-AA, EGF, and bFGF, but supplemented with 2% FBS for three days prior to fixation with 4% paraformaldehyde and subsequent staining.  The cell-surface marker GalC was detected by indirect immunofluorescence (green) in ≥30% of the cells in the culture.  Nuclei were stained with DAPI (blue).
GIBCO® rGPCs can be further expanded for at least one passage upon thawing in GPC recovery media (StemPro® NSC SFM, GlutaMAX™-I, and PDGF-AA).  The proliferation abilities afford researchers a more than 2-fold increase in cell numbers while the cells retain their typical morphology (Figure 3).
