Karyotype	model number = 39; range = 38 to 41. This is a hypodiploid human cell line with the modal chromosome number of 39, occurring in 62% of cells. The rate of cells with higher ploidies was 16%. Sixteen markers were found in single copies in all cells. They include del(2) (q34), del(8) (p21), 14p+, der(X)t(X;14) (q28;q13), t(3q8q) and eleven others. A few different markers, all of which had 11qter--11p13 [der(11)] in common, were found. These markers appeared to be mutually exclusive, each cell having one, and only one, marker at a time. Normal X, N8, N11, N21 and N22 were absent. N1, N10, N15, and N16 were paired, and other normal chromosomes were single.
Derivation	This line was derived by J. Sykes (see also ATCC HTB-33) in 1974.
Clinical Data	female Caucasian 47 years
Antigen Expression	Blood Type AB; Rh+
Tumorigenic	Yes, in nude mice; forms poorly differentiated epidermoid carcinoma (grade III).
Comments	MS751 cells have been reported to contain human papilloma virus 18 (HPV-18) sequences. More recently, it has been shown that MS751 cells contain a partial HPV-45 genome, and that HPV-45 sequences from the E6/E7 region are expressed as poly(A)+ RNA.

Complete Growth Medium	The base medium for this cell line is ATCC-formulated Eagle''s Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
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. Remove and discard culture medium. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53mM EDTA solution to remove all traces of serum which contains trypsin inhibitor. 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. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Incubate cultures at 37°C. Subcultivation Ratio: 1:2 to 1:5 Medium Renewal: Every 2 to 3 days 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.
