title: [Effect of recipient derived bone marrow stromal cells on immunological rejection in mouse allogeneic skin transplantation].
abstract: OBJECTIVE
  To investigate the effect of recipient derived bone marrow stromal cells (BMSCs) on immunological rejection in mouse allogeneic skin transplantation.
  
  
  METHODS
  The C57BL/6 to BALB/c allogeneic skin transplantation model was created. The bone marrow stromal cells (BMSCs) were isolated from BALB/c by gradient density centrifugation and adhesion separation. The BMSCs were injected back through tail vein. The mouse were divided into three groups as group A (BALB/c + BMSCs), group B (BALB/c with skin transplantation), and group C (BALB/c with skin transplantation + BMSCs). The pathologic examination of the graft was performed and the cytokines such as IL-2, IFN-gamma were detected at the different time.
  
  
  RESULTS
  The attained BMSCs in the experiment had the characteristics of BMSCs. The acute immunological rejection reaction detected by immunohistochemistry staining was alleviated noticeably in group C than that in group B. The concentrations of cytokines IL-2, IFN-gamma in group B were lower than that in group C at 7 d (F = 248,954.6, P < 0.05; F = 148,311.7, P < 0.05) and 14 d (F = 117,372.3, P < 0.05; F = 126,743.3, P < 0.05) after skin transplantation.
  
  
  CONCLUSIONS
  Recipient derived BMSCs transfusion can alleviate the acute immunological rejection after allogeneic skin transplantation. The possible mechanism maybe related to the inhibitory effect on the secretion of cytokines like IL-2, IFN-gamma.
