Tool Details

  • Tool name: fR2 Cell Line
  • Tool type: Cell Lines
  • Parental cell line:
  • Organism: Human
  • Tissue: Breast
  • Cancer type: Breast cancer
  • Disease: Cancer
  • Description: fR2 cells have been shown to express Muc-1, also known as HMFG-1 antigen, which is a mucin-like component of human milk fat globule membranes. They are positive for keratin 8 and 18, but negative for keratins 4, 6, 7, 10, 13, 14, 16, 17 and 19. Although fR2 is morphologically different from fR5, they have probably been derived from a common precursor cell since the karyotypes are similar. Karyotype analysis revealed hypotetraploidy and several rearrangements involving chromosome 1 and 11 which are frequently found in breast carcinomas and lines derived from metastatic pleural effusions. fR2 cells display anchorage independent growth in soft agar and are positive for SV40 T-antigen. Early passages were non-tumorigenic in nude mice.
