Table 1 Twenty-one primary tumors cell lines derived from ECs in F1, F2 and N1 progeny after crosses between EC susceptible BDII females and EC non-susceptible SPRD and BN males.

From: SKY analysis revealed recurrent numerical and structural chromosome changes in BDII rat endometrial carcinomas

  1. Background: genetic background of the animals that developed tumors (cross of BDII females to SPRD or BN males); Progeny: F1 - first generation intercross offspring; F2 - second generation intercross offspring; N1 - first back-cross generation offspring; Ploidy level: number of methaphases that showed diploid, triploid, tetraploid or other (near haploid, pentaploid and hexaploid) karyotype.
