Impact of integrin-matrix interaction and signaling on insulin gene expression and the mesenchymal transition of human beta-cells.

Abstract excerpt

A critical shortage of donor pancreata currently prevents the development of a universal cell-based therapy for type I diabetes. The ex vivo expansion of insulin-producing beta-cells offers a potential solution but is problematic due to the inherent tendency of these cells to transition into mesenchymal-like cells that are devoid of function. Here, we demonstrate for the first time that exposure to elements of...
