WebNov 18, 2024 · The notochord drives longitudinal growth of the body axis by convergent extension, a highly conserved developmental process that depends on non-canonical Wnt/planar cell polarity (PCP) signaling. However, the role of cell-matrix interactions mediated by integrins in the development of the notochord is unclear. WebResults: Loss of the CCN2 gene in notochord-derived cells disrupted the formation of IVDs in embryonic and newborn mice, resulting in decreased levels of aggrecan and type II collagen and concomitantly increased levels of type I collagen within the nucleus pulposus. CCN2-knockout mice also had altered expression of CCN1 (Cyr61) and CCN3 (Nov).

Notochord - an overview ScienceDirect Topics
WebThe notochord is a direct derivative of the node and is, like the node, an important signaling center in the developing embryo (Selleck and Stern, 1991), both for the adjacent somites and for the overlying neural plate tissue.

WebNotochord Diagram Features It is a cellular structure that runs along the longitudinal axis of the embryo and ventral to the central nervous system. It is composed of glycoproteins that are packed in a sheath of collagen fibres that has been wound into two opposing helices. The glycoproteins are deposited in vacuolated and turgid cells. sharp android tv
