摘要: The Paraxis gene encodes a basic helix-loop-helix (bHLH) transcription factor expressed in paraxial mesoderm and whose mutant displays an inability to form epithelial somites. We analyzed the later expression pattern of transcripts chick limb. are located Pax3-expressing myoblasts migrating from somites persist proliferating limb bud. Moreover, QH1 antibody, which recognizes quail endothelial cells, reacts with subset Paraxis/Pax3 expressing cells is then down-regulated during muscle differentiation.
