Extensive adipocyte differentiation was confirmed by Oil Red O staining and expression of adipocyte markers FABP4 and LEP, and there were no differences when comparing differentiated visceral adipose tissue-derived cells (Vis AD) and differentiated subcutaneous adipose tissue-derived cells (Sub AD) (Supplementary Fig. 2a–c), thereby excluding a potential differentiation bias. The gene discussed is FABP4; the disease is Alzheimer disease.
