Derivation
The chondrocyte cell line, CHON-001, was derived from the long bones of an 18-week old female fetus. The primary cells were infected by the defective retrovirus containing hTERT gene under G418 selection. The defective retrovirus was collected from the supernatant of the packaging cell line, PT67 transfected with the pLXSN vector containing hTERT gene.
Antigen Expression
Antigen expression: This cell line expresses the following proteins (Homo sapiens): HLA-B58, HLA-B81, HLA-Cw6, HLA-Cw8, HLA-DR7, HLA-DR12, HLA-DR52, HLA-DQ2, HLA-DQ5.
Genes Expressed
Positive for Collagen type I and aggrecan (RT-PCR). Negative for Collagen type II (RT-PCR).
Complete Growth Medium The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium:
  • 0.1mg/ml G-418
  • 10% heat-inactivated fetal bovine serum
Subculturing
Volumes are given for T-75  flasks; proportionally reduce or increase the amount of dissociation medium for culture vessels of other sizes.
  1. Remove and discard culture medium.
  2. Add 2.0-3.0 mL of 0.05% Trypsin-0.53mM EDTA solution to the flask and observe cells under an inverted microscope until the cell layer is dispersed (usually within 5 to 10 minutes).
    Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to to detatch may be placed at 37°C to facilitate dispersal.
  3. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  4. Transfer cell suspension to a centrifuge tube and spin at approximately 125 x g for 5 to 15 minutes.
  5. Discard supernatant and resuspend cells in fresh growth medium.
  6. Add appropriate aliquots of cell suspension to new culture vessels. An inoculum of 2 X 103 to 3 X 103 viable cells/cm2 is recommended. Subculture when cell concentration reaches between 1 x 104 and 2 x 104 cells/cm2.
  7. Incubate cultures at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:6 is recommended

Population Doubling Level (PDL) As part of our quality control, we have tested this cell line for its ability to grow for a minimum of 15 population doublings after recovery from cryopreservation. We have also compared its karyotype, telomerase expression level, growth rate, morphology and tissue-specific markers when first recovered from cryopreservation with that of cells at 10+ population doublings to ensure that there is no change in these parameters and that the cells are capable of extended proliferation.
