Good news!
"An interdisciplinary team of researchers ... has developed a first-of-its-kind roadmap of how human skeletal muscle develops, including the formation of muscle stem cells. ... identified various cell types present in skeletal muscle tissues, from early embryonic development all the way to adulthood. Focusing on muscle progenitor cells, which contribute to muscle formation before birth, and muscle stem cells, which contribute to muscle formation after birth and to regeneration from injury throughout life, the group mapped out how the cells’ gene networks — which genes are active and inactive — change as the cells mature."
