Abstract
The goal of this study has been to evaluate adipose tissue derived stem cells (ADSCs) from infrapatellar fat pad and characterize their cell surface markers using anti-human antibodies, as adipose tissue derived stem cells (ADSCs) have great potential for cellular therapies to restore injured tissues. Adipose tissue was obtained from infrapatellar fat pad of sheep. Surface markers evaluated by flow cytometry. In order to evaluate cell adhesion, the Polycaprolactone (PCL) was sterilized under Ultraviolet (UV) light and about 1×10(5) cells were seeded on PCL. Then, ASCs- PCL construct were evaluated by Scanning Electron Microscopy (Mira3 Te Scan, Czech Republic). We showed that adipose tissue derived stem cells (ADSCs) maintain their fibroblastic-like morphology during different subcultures and cell adhesion. They were positive for CD44 and CD90 markers and negative for CD31 and Cd45 markers by human antibodies. Our results suggest that ASCs surface markers can be characterized by anti-human antibodies in sheep. As stem cells, they can be used in tissue engineering.
Highlights
Tissue engineering, as a new approach to reconstruction and regeneration of damaged tissues, is used to repair the injured tissues.[1]

Results of this study indicated that infrapatellar fat pad adipose tissue derived stem cells maintain fibroblast-like morphology, cell specific adhesion, and test strongly positive for CD90 and CD44
Summary
As a new approach to reconstruction and regeneration of damaged tissues, is used to repair the injured tissues.[1]. The efficacy of ASCs for tissue regeneration is currently under assessment in clinical trials.[5]
