Flow cytometric analysis of CD4+Foxp3+ Tregs as a proportion of lymphocytes from lymph nodes. By qRT-PCR analysis of mRNA extracted from cardiac xenografts, relative expression levels of Foxp3+ were increased on day 2 in the combination group, compared with the control group (*P<0.05) and on day 7 in the combination group, compared with the Lef group (P<0.05).
