Comparison Of The Effect Of Adipocyte-Derived Stem Cells And Curcumin Nanoliposomes With Phenytoin On Open Cutaneous Wound Healing In Rats

Background: Reducing the healing time of wounds can decrease the patient's immobility time and their medical costs, leading a faster return of the patients to daily work.Objective: The aim of the present study is to compare the effect of adipose-derived stem cells and curcumin-containing liposomal nanoparticles with phenytoin on wound healing.Methods: After anesthesia of the rats, open skin ulcers were made by a bistoury blade. Subsequently, stem cells were removed from the adipose tissue of the upper border of the epididymis. The originality of stem cells was then confirmed by the flow cytometry. The fusion method was used to prepare the liposome; and also, nanoliposomal particles were confirmed by using the DLS microscope. The percentage of recovery and the cell count was measured with IMAGEJ. The expression of genes was assessed by PCR. The number of fibroblasts was counted by immunohistochemistry techniques. The amount of collagen was determined by Tri-chromosome staining, and the number of capillaries was enumerated by H & E staining.Results: The expression of the TGF-beta 1 gene, vascular number, wound healing rate and the number of fibroblasts increased significantly in adipose tissue-derived stem cells and curcumin nanoliposome groups (p<0.05); the wound surface was also decreased significantly (p<0.05).Conclusion: Based on the results of our research, adipose tissue-derived stem cells and curcumin nanoliposomes can heal wounds efficiently.
