YARAK, Samira and OKAMOTO, Oswaldo Keith. Human adipose-derived stem cells: current challenges and clinical perspectives. An. Bras. Dermatol. [online]. 2010, vol.85, n.5, pp.647-656. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962010000500008.
Adult or somatic stem cells hold great promise for tissue regeneration. Currently, one major scientific interest is focused on the basic biology and clinical application of mesenchymal stem cells. Adipose tissue-derived stem cells share similar characteristics with bone marrow mesenchymal stem cells, but have some advantages including harvesting through a less invasive surgical procedure. Moreover, adipose tissue-derived stem cells have the potential to differentiate into cells of mesodermal origin, such as adipocytes, cartilage, bone, and skeletal muscle, as well as cells of non-mesodermal lineage, such as hepatocytes, pancreatic endocrine cells, neurons, cardiomyocytes, and vascular endothelial cells. There are, however, inconsistencies in the scientific literature regarding methods for harvesting adipose tissue and for isolating, characterizing and handling adipose tissue-derived stem cells. Future clinical applications of adipose tissue-derived stem cells rely on more defined and widespread methods for obtaining cells of clinical grade quality. In this review, current methods in adipose tissue-derived stem cell research are discussed with emphasis on strategies designed for future applications in regenerative medicine and possible challenges along the way.
