The Effect of Topical Gel Secretome Hypoxia Mesenchymal Stem Cells (SH-MSCs) on TGF-Β and IL-6 Gene Expression in Wistar Rats Excision Wound Models

Abstract

Wounds on the skin result in damage to the epithelial tissue and skin structure, hampering wound healing and causing acute wounds to become chronic. Secretome Hypoxia Mesenchymal Stem Cells are capable of secretes cytokines and growth factors, including TGF-β which are useful for wound healing. IL-6 is a pro-inflammatory cytokine that is produced in infectious lesions and is also important in wound closure. The aim of the research was to prove the effect of topical SH-MSCs gel on TGF-β and IL-6 gene expression in male Wistar rats with an excision wound model. This study aims to prove the effect of topical gel administration secretome Hypoxia Mesenchymal Stem Cell (SH-MSCs) on TGF-β and IL-6 gene expression in male Wistar rats with an excision wound model. This study is Experimental research with Post-test Only Control Group Design. The number of samples was 18 male Wistar rats with the excision wound model divided into three groups, Group I (K-) was given a basic gel placebo, Group 2 (K+) was given a Clobetasol dose of 0.25g/kg, and Group 3 (P1) was given SH-MSCs gel at a dose of 400 μl/kg BW, treatment for 5 days, on day 6 the skin tissue was examined by RT-PCR to see the expression of the TGF-β and IL-6 genes analyzed by One Way Anova test, continued by Post Hoc LSD test. The average TGF-β gene expression in the P1 group was the highest (1.38) and the mean IL-6 gene expression in the P1 group was the lowest (0.72). One Way Anova test result showed a significant difference in TGF-β gene expression with a value of p=0.056 (p<0.05) and IL-6 p=0.47 (p<0.05). Post Hoc LSD test result on TGF-β gene expression shows that administration of 400μl/kg BW SH-MSCs can increase TGF-β gene expression and reduce IL-6 expression in Wistar rats with an excision wound model. The administration of topical gel SH-MSCs dose of 400 μl/kg BW was proven to significantly increase TGF-β levels in male Wistar rat excision wound model. The administration of topical SH MSCs dose of 400 μl/kg BW can reduce IL-6 levels in male Wistar rat excision wound models.
