Effects of establishing cell cultures and cell culture conditions on the proliferative life span of human fibroblasts isolated from different tissues and donors of different ages.
It is well known that normal human cells placed in a culture environment exhibit a limited proliferative capacity. The extent to which the culture environment influences proliferative life span is not understood. This study evaluated the effects of the standard procedures used to establish and maintain cultures on the proliferative life spans of different types of human fibroblast cells established from fetal and adult skin and lung. The results of this study demonstrate that procedures to establish cell cultures use only one of several subpopulations of cells present in biopsy pieces and that the culture conditions routinely employed by most laboratories can exert significant effects on proliferative life-span determinations. The maximum proliferative life span differed significantly when obtained by growing the cells in two commonly used commercial media. Proliferative life span was inversely related to ambient oxygen tension and directly related to seeding density in all of the lines examined although lines established from adult skin were much more resistant to toxicity. Enzymatic antioxidant defense levels of fetal skin fibroblasts were much lower than those observed in adult skin fibroblasts, but the effects of oxygen on their life spans were similar. Hyperoxia induced larger increases in glutathione concentration in cell lines with low antioxidant enzyme levels.
