Figure 1: Flow cytometric analysis of recipient peripheral blood revealed that GFP+-ASC cell populations were significantly increased at one week and two weeks post-transplant in animals treated with GFP+ASCs and short-term CsA-ALS, compared to the controls. The GFP+-ASC cell expressions in recipient circulating blood still existed at 16 weeks post-transplant in rats treated with GFP+-ASCs, CsA and ALS, although skewing decrease post-transplantation. The indicated signals were statistically significant (P<0.05).
