Scientists from the universities of Eindhoven and Maastricht (the Netherlands) for the first time managed to grow a piece of pig skeletal muscle. Experts led by Mark Post-Turing identified in animals called mioblasty - "repairman" that transformed the extent of growth and regeneration in normal muscle cells.

Biomaterial placed in culture media, created by substances circulating embryonic blood (in the future the researchers plan to replace their synthetic analogs).

According MEMBRANA.ru from exile to Gizmag, as a result of prolonged incubation of cells received a full sample of muscle tissue, however, until nayapetytnishyy in appearance. It is one of the most important selection criteria grown "chops", as opposed to family cultivation experiments with tissue-implant.
