Most animals undergo gastrulation to establish germ layers and embryonic axes. The dynamic morphogenetic cell movements that take place during gastrulation are highly coordinated. In Xenopus embryos, these cell movements, which include involution and convergent extension, are driven predominantly by mesodermal cells (Keller, 1991; Keller et al., 1992). This is particularly obvious during conver...
The Shiite school has been the promoter of movements that have stood up to oppression, and this political thought has shaped Shiite political and social movements and movements throughout history. Historically, the turning point of the Shiite revolution and the formation of Shiite protest movements and events is the Ashura event, and the land of Karbala as the holy land of the Shiites and the p...
Convergent extension movements occur ubiquitously in animal development. This special type of cell movement is controlled by the Wnt/planar cell polarity (PCP) pathway. Here we show that Xenopus paraxial protocadherin (XPAPC) functionally interacts with the Wnt/PCP pathway in the control of convergence and extension (CE) movements in Xenopus laevis. XPAPC functions as a signalling molecule that...
Recent genetic studies in Drosophila identified a novel non-canonical Wnt pathway, the planar cell polarity (PCP) pathway, that signals via JNK to control epithelial cell polarity in Drosophila. Most recently, a pathway regulating convergent extension movements during gastrulation in vertebrate embryos has been shown to be a vertebrate equivalent of the PCP pathway. However, it is not known whe...
