In his current research, there are still gaps to fill: how the CYP26B1 gradient is regulated, how retinoic acid connects to the Shox The gene and what downstream factors determine the formation of specific structures, such as the humerus or the radius bones.From healing to regenerationMonaghan explains that Axolotles do not have a “magic gene” for regeneration, but share the same fundamental genes as humans. “The different key lies in the accessibility of these genes. While an injury in active men of genes which induce scars, in the salamanders Cell dedifferentiation: Cells return to an embryonic type state, where they can respond to signals such as retinoic acid. This competence to return to a “state of development” is the basis of their regeneration, “explains the researcher.I know that if humans have the same genes, why can’t we regenerate? “The.
