Characterization of FAP expression level in BM-MSCs.

<p>(A) Analysis of the mRNA expression levels of FAP in different human cell lines as indicated. Quantification was carried out by qRT–PCR as described in the Materials and methods section. The error bars are showing standard deviation (SD). (B) Expression of FAP detected by western blot analysis with anti-FAP antibodies. Immunoblotting with anti-actin antibodies was used as a loading control.
