Effectiveness of Dental Pulp Stem Cells-Secretome on Superficial Burn Wounds

Dental Pulp Stem Cells (DPSCs) represent a new therapeutic alternative for treating superficial burn wounds. This study aimed to evaluate the effectiveness of DPSC-derived secretome on superficial burn wounds in an animal model. The study employed a post-test-only controlled group design using 15 rats with superficial burns. Rats were divided into a negative control group of 0.9% NaCl (K1), a positive control group of moist-exposed burn ointment or MEBO (K2), and a treatment group of DPSC-secretome (K3). The effectiveness of the DPSC-secretome was assessed by wound area percentage and histopathological observations on days 5, 14, and 21. DPSCsecretome significantly reduced the burn wound area (p<0.05). Histology data showed that the DPSC-secretome promoted re-epithelialization, fibroblasts, and collagen formation. Polymorphonuclear cells were also reduced after 21 days, indicating that the DPSCs-secretome has an anti-inflammatory effect. In addition, the DPSC-secretome and MEBO showed equal effects on angiogenesis after 14 days. The DPSC-secretome was more effective than MEBO on superficial dermal burns. This study showed that the DPSC secretome has therapeutic potential for burn wounds.
