Caspase-3 regulates ureteric branching in mice via cell migration

Inhibition of caspase-3 (Casp3) reduces ureteric branching in organ culture but the mechanism remains unclear. Since Casp3 has non-apoptotic functions, we examined whether Casp3 regulates ureteric branching by promoting cell migration, using a ureteric bud (UB) cell line and Casp3-deficient (Casp3−/−) mice. Also, we examined whether Casp3 plays a role in the reduced ureteric branching of metanephroi from nutrient restricted mothers, in which...
