Transplanted bone marrow stromal cells are not cellular origin of hepatocellular carcinomas in a mouse model of carcinogenesis

Figure 1 Immunofluorescence of α-fetoprotein and albumin in bone marrow stromal cells, with or without treatment of HGF in culture (× 400). A: α-fetoprotein expression was negative in the absence of HGF; B: Albumin expression was negative in the absence of HGF; C: α-fetoprotein expression localized at the cytoplasm in hepatocyte-like BMSCs; D: Albumin expression localized at the cytoplasm in hepatocyte-like BMSCs.
