Abstract

We describe the expression pattern of cMCAM, a cell adhesion molecule of the immunoglobulin superfamily, in early chick embryonic development by in situ hybridisation. An initial ectodermal domain of expression is subsequently expanded, and cMCAM is expressed in the neural crest cells, otic vesicle, heart primordium, notochord and endoderm. In addition, cMCAM expression localises in the myotome once the somite cells have been specified. An in vitro murine cellular system allowed us to confirm that MCAM expression coincides with the onset of myogenic cell determination.
