31. Lentigines are distinguished from freckles ( ephelis ) based on the proliferation of melanocytes . 32. Endogenous OA1 protein expressed by normal human melanocytes is detected as a 60kDa protein. 33. The normal zebrafish embryo, above, shows the migration and maturation of melanocytes . 34. Ultraviolet light induces melanin production from melanocyte cells to cause sun tanning of skin. 35. I've read our articles on linea nigra and melanocyte -stimulating hormone. 36. Vitiligo results from the loss of melanocytes . 37. In addition to eumelanin, melanocytes can generate a yellow / red pigment called phaeomelanin. 38. In melanocytes , melanosomes ( vesicles containing the pigment melanin ) are transported on microtubules. 39. It stimulates melanocytes to produce melanin, and can also be cleaved into smaller peptides. 40. These mutations disrupt dimer formation, and as a result cause insufficient development of melanocytes .
