Physical mapping of human chromosome 17 using fragment-containing microcell hybrids.
Hybrid cell lines were generated by microcell-mediated transfer of human chromosome 17 into rat recipient cells. The genotypes of 36 such lines were analyzed using a set of human chromosome 17-derived sequences to probe the structural integrity of the chromosome. Four classes of hybrids were obtained: clones with an apparently intact chromosome 17, clones containing large fragments of the chromosome including both the centromere and the selected marker, clones containing only the selected marker and flanking sequences, and clones containing two 17-derived fragments--the pericentric region plus the region of the selected marker. Data from these hybrids were used in conjunction with published regional localization information to obtain a provisional linear map of the chromosome. Results of this analysis are compared to the gene maps predicted from recent linkage studies and from other somatic cell hybrid experiments.
