| Abstract: | Fibroblast cultures derived from skin biopsies of patients with Fanconi anemia had doubling times (mean of five lines: 30.3 ± 0.2 hours) significantly longer than randomly selected normal controls (mean of nine lines: 22.9 ± 0.4 hours). Control cultures grew more slowly in the enriched media RPMI 1640 and McCoy's 5A than in MEM, while a culture from a patient with Fanconi anemia grew more slowly only in McCoy's 5A. Differences in growth characteristics between Fanconi anemia and normal cell cultures may be useful in analyzing the metabolic error determined by the Fanconi anemia gene. |
