Sequence of vascular patterning and gene transcription in the chick chorioallantoic membrane (15.1)

2014

Introduction: The chick chorioallantoic membrane (CAM) is a well-established model of both vasculogenesis and angiogenesis; however, little is known about the genetic control of vascular patterning in the CAM. Methods: Using recent advances in chicken genomics, we investigated the relative expression of 84 angiogenesis genes during the growth and remodeling of the CAM microcirculatory network. Chick embryos, cultured ex ovo, were studied during embryonic development days (EDD) 8-14. UV laser microdissection was used to harvest capillary plexus and 1st, 2nd, and 3rd order conducting vessels for qRT-PCR analysis. Results: Two transcription peaks were observed between EDD 8 and 14. The first p…
