Effects of bone marrow derived-mesenchymal stem cells (BMSCs), platelet-rich plasma (PRP), BMSCs + PRP, or standard treatment (PIS) on (A) matrix metalloproteinase (MMP9) level and (B) transforming growth factor beta (TGF-β) mRNA expression in a full-thickness skin burns in rats. TGF-β was also examined immunohistochemically as shown in palate C (100x). Results of biochemical assays are expressed as mean ± SD values (n = 7), whereas, gene expression results are expressed as the mean ± SD of triplicate assays and adjusted to GAPDH. The letters (a and b) indicate statistical differences at P < 0.05 in comparison with the control and the model groups, correspondingly.
