| pubmed-article:6773878 | pubmed:abstractText | A human uveal melanocyte-derived cell line (U1I) is described. The cell line has a doubling time of 27.2 hr, a plating efficiency on plastic surfaces of 10%, and a cloning efficiency in soft agar of < 0.1%. U1I displays marked chromosomal aneuploidy and sensitivity to ultraviolet light. Biochemical studies indicate the presence of tyrosinase, which is stimulated by several compounds, including theophylline, progesterone, and nerve growth factor. | lld:pubmed |
