ABSTRACT
<p><b>OBJECTIVE</b>To compare the in vivo immune reaction of transplanting porcine MSC-derived CLC with rabbit cardiomyocytes extracts induced differentiation or in vitro cultured porcine MSC.</p><p><b>METHODS</b>After injecting the MSC-derived CLC or MSC to the original porcines, the number of CD4+, CD8+ T cells were determined by flow cytometry. The serum concentrations of IL-2, IL-4 were measured by ELISA, and the porcine spleen lymphocyte CTL cytotoxicity was determined by Cell Counting Kit-8 Assay.</p><p><b>RESULTS</b>The numbers of CD4+ and CD8+ T cells, the serum concentrations of IL-2, IL-4 and spleen lymphocyte CTL cytotoxicity were all similar in porcines received MSC-derived CLC induced by rabbit's CMs extract or MSC transplantation.</p><p><b>CONCLUSION</b>The porcine MSC-derived CLC induced by rabbit's CMs extract did not induce extra immune reaction when injected back to the original porcine.</p>
