Fig. 5. Expression of neuronal and glial markers by GFP-negative PD SN AHNPs under differentiating conditions in DM2 and DM3, and a comparison of the yield of TH+ neurons among PD AHNPs from four brain regions.
(A) Both DM2 and DM3 incubated cultures gave rise to neurons and astrocytes. The presence of FGF8 and SHH did not distinctly enhance TuJ1-positive, GFAP-positive and TH-positive cell numbers among the GFP-negative PD population (p>0.05). (B) PD AHNPs from SN, SVZ, HC, and CX were co-cultured with mouse GFP-ESNPs in DM3 media to induce differentiation. GFP–/TuJ1+, GFP–/TH+ and GFP–/GFAP+ cells were found in PD cell co-cultures derived from all four brain regions after 8 days of induced differentiation. SN-derived PD AHNPCs generated the lowest amount of TH+ neurons, while the highest proportion of TH+ neurons was found in CX-derived PD AHNPs (CX>HC>SVZ>SN, n=5 per region, p<0.01).
