11. SCF also regulates survival and proliferation of fully differentiated melanocytes in adults. 12. Tyrp1 is a melanocyte -specific gene product involved in melanin synthesis. 13. This results in increased concentrations of the melanogenic enzymes within the melanocyte . 14. In the absence of this signal, melanocytes produce phaeomelanin. 15. Lerner also isolated the compound melanocyte -stimulating hormone ( MSH ). 16. Melanoma is a rare but aggressive malignant cancer that originates from melanocytes . 17. As they mature, melanocytes and nerve cells continue to share some attributes. 18. Like nerve cells, melanocytes develop branching processes that attach to nearby cells. 19. All adults have about 60, 000 melanocytes per square inch of skin. 20. The pigment is produced in a specialized group of cells known as melanocytes .
