Researchers solve a molecular mystery in muscle
The muscle-building abilities of hormones known as insulin-like growth factors (IGFs) are legendary. Just do an online search and you'll find not only scientific papers discussing the effects of IGFs on the cells that give rise to muscle tissue, but also scores of ads touting the purported benefits of IGF supplements for bodybuilding.

"These are opposite and mutually exclusive cellular events---once a muscle cell divides, it can't differentiate, and once it differentiates, it can never divide again," Duan said.
"The myoblasts' response is controlled by oxygen availability," said Duan.
