XW4.4 induced pancreatic differentiation of rat bone marrow derived mesenchymal stem cells into insulin-producing cells shown to release C-peptide and insulin in response to physiological or high glucose levels, which could lead to a possible treatment for Type 1 diabetes. Its mechanism of action is postulated to be through increasing expression of hepatocyte nuclear factor 3β (HNF3β), a member of the forkhead box transcription factor family that regulates expression of several genes in the pancreas during early embryogenesis.
