Human melanoma cell lines: morphology, growth, and alpha-mannosidase characteristics. 1982

J Siracký, and M Blasko, and J Borovanský, and J Kovarík, and J Svec, and M Vrba

Four human melanoma cell lines were characterized by evaluation of the morphology, ultrastructure, cytogenetics, plating efficiency, agar colony formation and alpha-mannosidase values. Biochemical studies demonstrate that all studied lines produced alpha-mannosidase even under condition of long-term in vitro growth. All respective lines were characterized by a great variations in biological markers studied and very few reliable comparisons could be obtained as regards the proliferation activity and capacity, cellular composition and clonogenic potential as well. Due to cellular selections during long-term in vitro cultivation, the range for using these experimental systems as models for the study of biology of human malignant melanoma seems to be rather limited.

UI MeSH Term Description Entries
D008361 Mannosidases Glycoside hydrolases that catalyze the hydrolysis of alpha or beta linked MANNOSE. Mannosidase
D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.
