RB1 and neoplasm: To examine the genetic divergence among these cell cultures, Pa, Pb, Ra, Rb and tumor-infiltrating lymphocytes (TILs, from recurrent tumor) were subjected to whole-genome sequencing (WGS), reaching > 60 × coverage, and whole-exome sequencing (WES) was also performed for Pa, Pb, Ra, and Rb, reaching > 100 × coverage.
