..., even in Ednrb -wild type cultures, KITL is insufficient to stimulate melanogenesis (Morrison-Graham and Weston,1993 ; Murphy et al.,1992 ; Reid et al.,1996), but the addition of TPA(Murphy et al., 1992) or EDN3(Reid et al., 1996) induces pigmentation. Similarly, the addition of TPA induces...

... and the SI locus cause deficiencies in gametogenesis, melanogenesis and hematopoiesis. The c-kit receptor is expressed in the cellular targets of IF and SI mutations, while KL is expressed in their microenvironment. In melanogenesis, c-kit is expressed in melanoblasts from the time they leave the neural...

... and the Sl locus cause deficiencies in gametogenesis, melanogenesis and hematopoiesis (erythrocytes and mast cells). The W-sash mutation differs from most W mutations in that it affects primarily mast cells and melanogenesis but not other cellular targets of W and Sl mutations. Thus, W sh / W sh mice...

... melanogenesis monoclonal antibody chick embryo Avian melanocytes in the skin derive from the neural crest (Dorris, 1939 ; Eastlick, 1939 ; Rawles, 1945 ; Le Douarin, 1982 ; Bagnara, 1987). The migratory route of the precursors of melanocytes following emigration from the neural tube has been...

... older corneas, in contrast, showed no evidence of even the first stages of melanogenesis. These results show, first, that some of the NC cells that invade the cornea are at least bipotent and hence representative of the POM population rather than being a unique subgroup and, second, that the acellular...
