Figure 2: PDGF-AA and BDNF do not influence mNPC proliferation. An mNPC growth curve (A), a Ki67 flow cytometry assay (B), and a BrdU flow cytometry assay demonstrate that PDGF-AA and BDNF do not stimulate NPC growth as measured after 4 days of treatment. All data is presented as compared to a complete media positive control as well as a minimal media control (a media non-conducive to cell proliferation). Data is quantified as the number of cells that stain positive for the dye over the total number of nuclei counted. *significance, p<.05.
