Fig. 6From: Adipose-derived stromal cells modulating composite allotransplant survival is correlated with B cell regulation in a rodent hind-limb allotransplantation modelIHC staining of C4d in transplanted tissue. a Immunohistochemical staining of C4d in alloskin biopsy specimens obtained at 2 and 6 weeks post-transplantation. Tissue sections obtained from six specimens were analyzed. b IHC staining analysis revealed a decrease in the expression of C4d in the ASC/ALS/CsA-treated group at 2nd and 6th weeks compared with that in the control (rejection) group at 2 weeks post-transplantation. *P < 0.05Back to article page
