Effect of differentiation of hydroalcoholic extract of berberis integrrima root on mesenchymal stem cells derived from adipose tissue of male Wistar rats

In the present study, the effects of hydroalcoholic extract of Berberis integrrima root on the induction of differentiation in mesenchymal stem cells derived from adipose tissue of male Wistar rats towards osteoblasts were investigated.

In this study, stem cells derived from male Wistar rat tissue were isolated and flow cytometry was performed to confirm the surface markers. Stem cells were treated with 10, 20, 40 and 80 μg/ml hydroalcoholic extract of B. integrrima root. The cell toxicity of the extract was evaluated by MTT assay and its differentiated effects was evaluated by alizarin red staining and alkaline phosphatase activity, calcium deposition assay. Results were analyzed using one-way ANOVA at a significance level of P <0.05.

Stem cells markers including CD105, CD44, and CD73 had positive, and CD45 and CD34 had negative expression in these cells. The results of the MTT assay showed Concentrations less than 20 µg/ml do not have significant toxic effects on cells. Higher alkaline phosphatase activity was observed in the treatment group compared to the control group on day 10. The results of Alizarin red staining and measurement of calcium content for 21days showed that this extract in a concentration dependent manner leads to the differentiation of stem cells into osteoblasts.

The findings of this study showed that mesenchymal stem cells derived from adipose tissue of male Wistar rats treated with hydroalcoholic extract of Berberis integrrima root enter osteoblasts in the differentiation pathway.
