| Popis: | We have generated pig–mouse somatic cell hybrids by fusing normal pig fibroblasts with an anchorage independent mouse cell line GM05267. High quality G-banding analysis was applied to a set of 18 hybrid cell lines derived from 15 independent hybrids and chromosomes were identified. Cytogenetic analysis showed that all hybrids contained one or several pig chromosomes with normal morphology devoid of any structural changes. Out of 18 hybrids tested for colony formation in soft agar, 15 were suppressed for anchorage independence while the remaining three were not suppressed. Correlation of the cellular phenotype with the pig chromosome content of the hybrids suggests that the suppressor function for anchorage independence is located on pig chromosome (SSC) 14. We have previously shown that a suppressor gene for anchorage independence (SAI1) is located on rat chromosome (RNO) 5 and another suppressor gene for the same phenotype is located on human chromosome (HSA) 9. Given the genetic homology of both RNO5 and HSA9 with two pig chromosomes including SSC14, the third suppressor gene we have mapped on SSC14 may well be a functional homologue of the previously identified rat and human genes. |
