BACKGROUND: Genetic analysis in the mouse revealed that GREMLIN1 (GREM1)-mediated antagonism of BMP4 is essential for ureteric epithelial branching as the disruption of ureteric bud outgrowth and renal agenesis in Grem1-deficient embryos is restored by additional inactivation of one Bmp4 allele. Another BMP ligand. BMP7. was shown to control the proliferative expansion of nephrogenic ... https://www.maximilianopellegrini.com/product-category/pigmentforandringer/
