Abstract: Secretion of procollagen was studied in human embryonal fibroblasts with diploid chromosomes as well as in fibroblasts obtained from fetuses after spontaneous abortion from patients with trisomy by chromosome 7. The rate of procollagen secretion was approximately similar in these cells; the protein was shown to accumulate in intracellular matrix of diploid fibroblasts, while it did not occur in the matrix of aneuploid fibroblasts. Content of polymeric tubulin was decreased in fibroblasts with trisomy as compared with diploid cells. Impairment of the intracellular matrix structure in the cells with trisomy appears to be responsible for deterioration of morphogenesis in human chromosome anomalies
