Adipose tissue-derived stem cells are a multipotent population of cells, easily extracted from adipose tissue. They are a group of heterogeneous stromal cells with a differentiation capacity into a variety of cell types, with the added advantage of a high proliferation rate. Studies have confirmed that the group of stromal cells can differentiate into mature adipocytes, chondrocytes, myocytes, neurons, hepatocytes, and different other cells in the vasculature system. These cells are offered for various in vitro assays, toxicological analysis, and cosmetic applications with the right quality control tests, performed in-house.
