The Effects of Wharton's Jelly Mesenchymal Stem Cells Associated with Gum of Pistacia atlanticafor Burn Wound Healing

Burn is a common wound in the world and consider the novel methods such as cell therapy can be a helpful strategy in the treatment. The purpose of the present study is investigating the effects of using ointment of animal oil mixed with Gum of Pistacia atlantica associated wharton's jelly mesenchymal stem cells (WJMSCs) on rat third-degree burn models.

In this experimental study, WJMSCs were extracted from human umbilical cord. For this study, 28 Wistar rats were burned by heating a metal rod of 1cm in diameter and then randomly divided into the control (7 rats) and treatment (21 rats) groups. The treatment group was divided into three groups (each group of 7 rats) of daily scrubbingof ointment, cell therapy, and cell therapy+ ointment. 106 cells (passage3) were injected into each rat subcutaneously. On day 30 after treatment, animals killed by chloroform and histological sections were prepared by staining Hematoxylsene-Eosin (H&E) and Trichromosone done for microscopic study.

Macroscopic and microscopic results indicated that in the experimental groups, the recovery was significantly more than the control. Also, the cell therapy+ ointment was significantly more effective than ointment and cell alone after 30 days. Histological analysis demonstrated a significant increase in angiogenesis, collagen synthesis, number of cells, thickness of skin layers, and totally acceleration wound healing in experimental groups compared to controls.

Based on these data, it can be suggested that simultaneous cell-therapy and traditional medicine accelerate the repair of skin burns in the animal models more significantly.
