Developmental regulation of somite derivatives: muscle, cartilage and tendon

Abstract

Recent research has broadened significantly our understanding of how the somite, a specialized mesodermal structure found in vertebrate embryos, gives rise to the cartilage, muscle and tendon cell lineages. The specification of somite derivatives involves the action of patterning signals secreted from adjacent tissue combined with the activation, in particular somitic compartments, of genes promoting cell lineage specification.
