Abstract (original English)

Stem cells have potential in the retrieval and repair of injured tissue and renovation of organ function. To date, several studies have been carried out to elucidate how differentiation of stem cells can be used in regenerative medicine applications. Adipose tissue is an abundant and accessible source of stem cell, useful for regenerative therapeutic use. Adipose stem cells (ASCs) are favorable for future translational research and can be applied in many clinical settings. Adipose tissue repair has been recently adopted in clinical trials to prove that ASCs can be successfully used in patients. Variability in cell culture procedures (isolation, characterization, and differentiation) may have an influence on the experimental outcome. In this report, we consider the selection mechanisms of ASCs using flow cytometry, cell culture, freezing/thawing, cell cycle evaluation, histochemistry/immunofluorescence, and differentiation of ASCs. Both researchers and regulatory institutions should consider a new policy for GMP procedures and protocols, paying special attention to stem cell bio-physiology, to facilitate more clinically oriented studies. ASCs show angiogenic properties, with prospects of repairing tissue damaged by radiotherapy, as well as possessing the ability to heal chronic wounds. They can also be useful in surgical practice. We focus on the potential clinical application o
