Pigment Cell Growth covers the proceedings of the Third Conference on the Biology of Normal and Atypical Pigment Cell Growth. The book focuses on the nature of the pigment cell and its contained melanin. The selection first offers information on the origin of the mammalian pigment cell and its role in the pigmentation of hair and relations between developing melanophores and embryonic tissues in the Mexican axolotl. The book also examines the genetic control of pigmentation in the fowl; relationship of atypical pigment cell growth to gonadal development in hybrid fishes; and estrogen, thyroid hormone, and the differentiation of pigment cells in the brown leghorn. The publication takes a look at dendritic melanoblasts in metastatic squamous cell carcinoma; microscopic analysis of normal melanoblasts, nevus cells, and melanoma cells; and analysis of skin color in living human subjects by spectrophotometric means. The selection is a dependable source of data for readers interested in pigment cell growth.
