Three-way control of fetal heart-cell proliferation could help regenerate cardiac cells
(PhysOrg.com) -- Heart muscle cells do not normally replicate in adult tissue, but multiply with abandoned during development. This is why the loss of heart muscle after a heart attack is so dire -- you can't ...
