Abstract/Description
-
Human mesenchymal stem cells (MSCs) are being evaluated for the treatment of a broad array of diseases due to their ability to secrete a variety of therapeutically beneficial paracrine-acting factors. For example, MSC conditioned media (MSC-CM) has been shown to inhibit hypoxia-induced apoptosis in human aortic endothelial cells (HAECs) via activation of the P13-AKT pathway. However, the factors secreted by MSCs responsible for this effect have yet to be identified. Recent studies have shown...
Show moreHuman mesenchymal stem cells (MSCs) are being evaluated for the treatment of a broad array of diseases due to their ability to secrete a variety of therapeutically beneficial paracrine-acting factors. For example, MSC conditioned media (MSC-CM) has been shown to inhibit hypoxia-induced apoptosis in human aortic endothelial cells (HAECs) via activation of the P13-AKT pathway. However, the factors secreted by MSCs responsible for this effect have yet to be identified. Recent studies have shown that the glycoprotein Follistatin-like 1 (FSTL1) activates the P13-AKT pathway by binding to the receptor disco-interacting protein (DIP2A) expressed on the surface of cells. Based on our data indicating that MSCs constitutively secrete high quantities of FSTL1, we hypothesize that this protein principally mediates the anti-apoptopic effect of MSC-CM on HAECs. Loss-of-function studies employing siRNA-mediated knockdown of the protein and neutralizing antibodies will be used to assess the role of FSTL1 in growth and survival of HAECs following exposure to hypoxic stress.
