Figure 9 Immunohistochemical analysis of albumin and alphafetoprotein in ADSC cells. Homogeneous expression of albumin (A-C) and AFP (D-F) in ADSC cells was further confirmed by immunocytochemistry. Staining for both albumin and AFP was negative in undifferentiated cells (A,D). ADSC cells homogeneously increase their protein expression levels in response to the differentiation protocol. Positive staining was shown after 14 d (B, E) and 21 d (C, F) of the 2-step differentiation protocol. AFP; alphafetoprotein.
