Background: Vitronectin

Vitronectin is a large glycoprotein found in blood and the extracellular matrix (ECM). As one of the major cell adhesion molecules in plasma, it interacts with integrins in the extracellular environment. Due to its many functions for cell biology including supporting the growth, maintenance and differentiation of stem cells, Vitronectin is a crucial molecule in stem cell therapy applications.

A truncated, E. coli derived version of human Vitronectin (aa62-292) has been optimized for large scale stem cell culture applications. This Vitronectin contains the RGD sequence necessary for interaction with cell-surface receptors to maintain its ability to act as a stem cell substrate.
