beta8 integrins are required for vascular morphogenesis in mouse embryos.

In order to assess the in vivo function of integrins containing the beta8 subunit, we have generated integrin beta8-deficient mice. Ablation of beta8 results in embryonic or perinatal lethality with profound defects in vascular development. Sixty-five percent of integrin beta8-deficient embryos die at midgestation, with evidence of insufficient… CONTINUE READING
