SK-UT-1B is a subline of the SK-UT-1 human uterine leiomyosarcoma cell line and grows in adherent culture. Although the SK-UT-1B cell line forms tumors when inoculated in immunocompromised mice, the resulting tumors are different from tumors produced by the parental SK-UT-1 cell line. This cell line displays relatively low chromosome instability, compared to other established cancer cell lines. SK-UT-1B maintains a near-diploid karyotype and is characterized by a very low percentage of polyploid cells. The SK-UT-1B cells have high levels of phosphorylated retinoblastoma protein, compared to the parental SK-UT-1 cells.
This is a subline of the SK-UT-1 cell line. The parental cell line was established in 1972 from a 75-year-old Caucasian female with a uterine mixed mesodermal tumor consistent with leiomyosarcoma grade III.
