Heterochromatin blocks of chromosome pairs 1, 9 and 16 as a 'marker' for human diploid cells Wi-38

Abstract

In analyzing human diploid cell strain Wi-38, by the use of C-bands, we have found that hetercchromatin blocks are equal on chromosome pairs 1 and 16, but are unequal on chromosome pair 9. These characteristics of the karyotype of Wi-38 cells may be used as a 'marker' for their identification.
