Here's why:
* Wnt9b is a signaling molecule that plays a key role in the development of the kidney, specifically in the formation of the glomerulus.
* It interacts with other signaling pathways, like the Ret pathway, to orchestrate the correct development of the glomerular structures.
* Wnt9b specifically regulates the differentiation of podocytes, which are the specialized epithelial cells that form the filtration barrier in the glomerulus.
* Mutations in Wnt9b gene are associated with kidney defects including congenital anomalies of the kidney and urinary tract (CAKUT).
While other biochemicals are involved in glomerulus development, Wnt9b is considered a master regulator due to its central role in initiating and guiding the complex process of glomerular formation.
