A study of catsharks reveals how alterations in the expression and function of certain genes in limb buds underlie the evolution of fish fins to limbs. The findings are reported by researchers from ...
Patterning of Limb Appendages The Hox genes, whose expression pattern seems to be the most relevant for subdividing the limb bud along the A-P axis and hence to potentially specify the unique outcome ...
Embryologists have clarified the role that retinoic acid plays in limb development. A new study showed that retinoic acid controls the development (or budding) of forelimbs, but not hindlimbs, and ...
