The LN-229 cell line was established in 1979 from cells taken from a patient with right frontal parieto-occipital glioblastoma [PubMed. 10416987].
Clinical Data
60 years
female
White
Oncogene p53 + (mutated, CCT (Pro) --> CTT (Leu) mutation at codon 98), PTEN + (wild type), p16 - (deleted), p14ARF - (deleted)
Tumorigenic Yes
Effects
Yes, forms tumors in nude mice
Comments
The cells exhibit mutated p53 (TP53) and possible homozygous deletions in the p16 and p14ARF tumor suppressor genes. They have a wild-type PTEN gene.

Stimulation of the cells with Fas ligand lead to apoptotic cell death within 16 hours. The cells were also killed by puromycin in a dose dependent manner.

Bcl-2 protects these cells from Fas ligand-induced cell death but was shown to have only a small protective effect on puromycin-induced apoptosis.


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: fetal bovine serum to a final concentration of 5%.
Subculturing Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Note: Subculture at 80% confluence. Cells pile up and do not become completely confluent.

  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53% (w/v) EDTA solution to remove all traces of serum that contains trypsin inhibitor.
  3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 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 detach may be placed at 37°C to facilitate dispersal.
  4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
  6. Incubate cultures at 37°C

Subculture Ratio: 1:4 to 1:6
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994
