A child born without limbs is found to have a mutation in a receptor for a fibroblast growth factor. The absence of limbs most likely resulted from a disruption of the processes controlling which of the following?

A) Apoptosis
B) Differentiation
C) Epithelial-mesenchymal conversions
D) Proliferation

I say D
if you believe in B, let me know why? plz


No idea, maybe D (based on the word " Growth" )


answer is D:

-- promotes the endothelial cell proliferation, the physical organization of endothelial cells into tiny tubes, promotes the formation of new blood vessels, in a process known as angiogenesis. bFGF is a more potent angiongenic factor than VEGF (vascular endothelial growth factor) or PDGF (platelet-derived growth factor). Apart from stimulating blood vessel formation, bFGF is an important player in wound healing. It stimulates the proliferation of fibroblasts that give rise to granulation tissue, which fills up a wound space/cavity early in the wound healing process.


D.-Proliferation for sure
