Among the body's most resistant tissues to repair, tendons and ligaments have long confounded medicine precisely because they lack the blood supply that makes healing possible elsewhere. Now, an international team led by Professor Chisa Shukunami at Hiroshima University has traced the formation of these tissues to a genetic switch — a 343-base-pair DNA enhancer conserved from ancient fish to modern humans — that governs when and where the Scleraxis gene awakens during development. The discovery, published in the journal Development, does not yet offer a cure, but it offers something perhaps mo
