Yes, in nude mice; tumors histologically resemble the original biopsy specimen and retain mucoepidermoid features

This is a human cell line with near-diploid chromosome counts. The modal chromosome number was 47, occurring in 36% of cells. The rate of cells with a higher ploidy count was 3.9%. Twelve markers were common to most cells. Among them were del(1) (q32.1), der (5)t(5;13) (p15.33;q11), i(5p), der(1)t(1;?) (p34.3;?) and der (6)t(6;7) (p25.3;q21.2). All markers were present in single copy per cell. Normal N1 and N6 were absent. There were two normal X chromosomes. No other abnormalities were detected.

This line was derived from a lymph node metastasis of a pulmonary mucoepidermoid carcinoma.
The cells were isolated in a chemically defined medium (HITES) and later adapted to growth in media supplemented with serum.
The cells retain their mucoepidermoid characteristics in culture as determined by their ultrastructure and expression of multiple markers of squamous differentiation.
The cells support the growth of hepatitis B virus and are negative for L-DOPA decarboxylase.
The line has been selected as a prototype for transfecting human subgenomic fragments into human cells for studying the role of HBV and its individual genes in the pathogenesis of viral hepatitis and liver cancer.
The cells stain positive for keratin and vimentin and are mucicarmine positive but are negative for neurofilament triplet protein.

Protocol:

1. Remove and discard culture medium.
2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM 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.

Subcultivation ratio: A subcultivation ratio of 1:3 to 1:8 is recommended

Medium renewal: Every 2 to 3 days
