Genetic elements that drive regeneration uncovered

Salamanders and fish possess genes that can enable healing of damaged tissue and even regrowth of missing limbs. The key to regeneration lies not only in the genes, but in the DNA sequences that regulate expression of those genes in response to an injury. Researchers have discovered regulatory sequences that they call ’tissue regeneration enhancer elements’ or TREEs, which can turn on genes in injury sites. —> Read More
