title: [Determination of free intracellular proline pool in fibroblast cultures].
abstract: By using a direct, rapid, sensitive colorimetric method, free intracellular proline pool from human adult skin fibroblasts in monolayer was determined. Thus under identical experimental conditions, free intracellular proline pool was about 20 pmol proline/micrograms cellular proteins, whatever the cell lines from human adult skin fibroblasts, the passage and the time of subculture. Besides, there was a poor correlation between collagen biosynthesis in fibroblast cultures and free intracellular proline pool.
