Abstract

Purpose: Natural biomaterials are a key base in tissue engineering, and collagen, as the maincontent of the extracellular matrix (ECM), is frequently used in tissue engineering. Aloe verahas some therapeutic effects on ulcers, therefore, the use of this natural resource has alwaysbeen considered for improving collagen function. We aimed to evaluate the effect of Aloe vera/Collagen blended on cell viability, cell attachment, and angiogenic potential by determining ofintegrin α1β1 and platelet endothelial cell adhesion molecule (PECAM-1) genes expression inhuman adipose-derived stem cells (hASCs).Methods: In this study, hASCs after harvesting of adipose tissues from abdominal subcutaneousadipose tissue and isolation, were cultured in four groups of control, collagen gel, Aloe veragel, and Aloe vera/collagen blended in vitro environment at 24h and then cell viability wasassessed by MTT (3-(4,5-dimethylthiazol 2-yl)-2,5-diphenyltetrazolium) assay. Integrin α1β1 andPECAM-1 genes expression were evaluated by real-time RT-PCR.Results: The results of MTT showed that the combination of Aloe vera/collagen was retained thecell viability at the normal range and improved it. In real-time RT-PCR results, integrin α1β1 andPECAM-1 gene expression were increased in the Aloe vera/collagen blended group comparedto the control group.Conclusion: For tissue engineering purposes, Aloe vera improves collagen properties in theculture of hASCs by increasing the expression of the integrin α1β1 and PECAM-1 genes.<br />
