(A) Nuclei plus Nile Red objects were normalized by the total nuclei count per image to report a percentage of differentiated cells (% Nile Red positive) as a function of passage and cell line. Purple bar = P3; orange bar = P5; green bar = P7. Error bars represent standard deviation; n=3. Statistical comparisons were made within cell lines, relative to P3. (B) Statistical analysis of percent adipogenesis data for comparison between cell lines. Purple shading = P3, orange shading = P5, green shading = P7. For (A) and (B), ****p<0.0001, ***p<0.001, **p<0.01, *p<0.05, ns = not significant, n/a = not applicable.
