The human chromosome arrays in eight different multi-chromosomal and seven monochromosomal hamster>human cell hybrids are indicated. Chromosomes are scored either by X or by o, depending on the ability of the hybrid clone to form stress bodies as determined by indirect immunofluorescence with anti-HAP antibodies. For each positive cell hybrid clone, the percentage of cells without or with one or more than one stress bodies is indicated on the right side of the Table. These figures were calculated on an average of three independent experiments counting at least 500 cells.
