The potential of adipose-derived adult stem cells as a source of neuronal progenitor cells

Adipose-derived adult stem cells are a population of mesenchymal stem cells extracted from discarded adipose tissue. Many have reported the differentiation of adipose-derived stem cells into chondrocytes, myocytes, osteoblasts, and, most recently, neural progenitor cells. This article covers the current state of the potential of the differentiation of adipose-derived stem cells into neuronal cells and an overview of their potential as adult stein therapies for neurological disorders. It has been reported that adipose-derived stem cells are capable of undergoing neuronal differentiation using protocols similar to that of Woodbury et al., which reported the differentiation of bone marrow stromal cells specifically into neurons. However, the transdifferentiation of bone marrow stromal cells into neuronal cells has recently fallen under intense criticism, which will likely place the plasticity of adipose-derived stem cells under scrutiny as well. To date, no group has produced evidence that adiposederived stem cells arc capable of differentiating to mature, functional neuronal cells in vitro. However, recent in vivo studies with adipose-derived stem cells are promising.
