...Elvin V. Leonard; Sana Safatul Hasan; Arndt F. Siekmann ABSTRACT Blood vessels form elaborate networks that depend on tissue-specific signalling pathways and anatomical structures to guide their growth. However, it is not clear which morphogenetic principles organize the stepwise assembly...

... showed a reduction in laminin protein expression in parenchymal basement membranes. Blood vessels in the Itga7 −/− brain showed separation from surrounding astrocytes and had reduced expression of the tight junction proteins claudin 5 and ZO-1. We propose that the alpha7 integrin subunit in astrocytes...

...Ceilidh Marchant; Peter Anderson; Quenten Schwarz; Sophie Wiszniak ABSTRACT Craniofacial development is a complex morphogenic process that requires highly orchestrated interactions between multiple cell types. Blood vessel-derived angiocrine factors are known to promote proliferation...
