Laminin-511 is a major component of the basement membrane, which is expressed in early development of the embryo and can be used as a matrix for pluripotent (ES/iPS) stem cells, as it binds to integrin on cell surfaces. However, Laminin-511 is a large protein (800kDa) composed of three chains (alpha, beta and gamma), making it difficult to produce recombinantly. In order to overcome this challenge, Laminin-511 proteins were fragmented to find the smallest integrin-binding component and hES cells were found to adhere more strongly to the E8 fragment than to the full-length protein. |
