Laminin-1, a heterotrimer of α1, β1, and γ1 chains specific to basement membrane, promotes cell adhesion and migration, proteinase secretion and metastases of tumour cells. Several active sites on the α1 chain have been found to promote B16–F10

In vitro matrigel angiogenesis assays

Autor: M L, Ponce

Publikováno v: Methods in molecular medicine. 46

A variety of in vivo and in vitro methods have been used to study angiogenesis, the process of blood vessel formation. Two widely accepted but technically difficult assays include the cornea implant assay and the chick chorioallantoic membrane assay.

An angiogenic laminin site and its antagonist bind through the alpha(v)beta3 and alpha5beta1 integrins

Angiogenesis is important for wound healing, tumor growth, and metastasis. Endothelial cells differentiate into capillary-like structures on a laminin-1-rich matrix (Matrigel). We previously identified 20 angiogenic sites on laminin-1 (alpha1beta1gam
