MultimericFasL™ is a high activity construct in which two trimeric FasL are artificially linked via the collagen domain of ACRP30. This construct very effectively mimics the natural membrane-assisted aggregation of FasL in vivo. FasL is a cytokine that binds to TNFRSF6/Fas, a receptor that transduces the apoptotic signal into cells. It is involved in cytotoxic T cell mediated apoptosis and in T cell development. 

FasL treatment of stem cells is a robust method for proliferating cells in culture while improving their stemness properties. Treatment with FasL results in a large quantity of Adipose Derived Stem Cells (ASC) of high quality.
