Chordoma: Other Cell Lines

 
 
GB60 and CH8
  • MTT assay found that cells from the CH8 and GB60 chordoma cell lines proliferated more rapidly in IMDM and DMEM media, but less rapidly in RPMI 1640. [1]
  • The novel CH8 chordoma cell line contained cells with chordoma-like morphology and gene transcripts that clustered close to chordoma tissue and cell lines upon gene array analysis. [1]
EACH-1
  • A cell line (EACH-1) was established from a human extra-axial chordoma after culturing the primary tumor, transplanting the cultured cells into the posterior abdominal flank of an immunocompromised nude mouse, removing the newly grown tumor 12 weeks post-transplantation, and growing the secondary tumor cells into a cell line. The doubling time for EACH-1 cultures was observed to be 37 hours. [2]
  • Western blot analysis showed that cells from the EACH-1 cell line exhibited decreased brachyury expression with the number of passages. After 30 passages, the cell line entered into crisis. [2]
  • FACS analysis on cells from the EACH-1 cell line found 91% positive for CD49f, 95% positive for CD49b, 92% positive for CD29, 96% positive for CD44, 93% positive for CD49c, 95% positive for CD59, 96% positive for CD73a, 97% positive for CD105, 94% positive for CD166, 5% positive for CD90, 27% positive for CD147, 2% positive for CD36, 3% positive for CD34, 1% positive for CD11b, 3% positive for CD19, 3% positive for CD45, 5% positive for CD117, 20% positive for CD3, 5% positive for CD184, 7% positive for CD79a, 7% positive for CD106, and 4% positive for CD133. [2]
  • Cytogenetic analysis by the G-bands method using trypsin and Wright staining on 21 metaphases for the EACH-1 cell line revealed unrelated diploid or hypotetraploid clones with aberrations. These aberrations included chromosomal rearrangements and loss (1p and 2p) or gain (5q and 20) of a part or the whole of multiple chromosomes. [2]
  • EACH-1 cells were observed to form colonies after 3 weeks of growth under non-adherent conditions, and this ability to form colonies was retained when the cells were incubated in suspension during 6 or 12 days. [2]
  • Serial subcutaneous transplantation of EACH-1 cells into nude mice resulted in tumor formation after 3-4 weeks. These tumor cells resembled the primary tumor cells that were used to establish the EACH-1 cell line. [2]
CM-319
  • RT-PCR analysis revealed expression of MRP1 and HIF-1α in the CM-319 chordoma cell line–expression of MDR1 was not detected. [3]
  • Western blot analysis revealed expression of MDR1, MRP1, and HIF-1α in the CM-319 chordoma cell line. [3]
