Comments |
SK-N-AS cells synthesize Insulin-like growth factor II (IFG-II) and IGF-II RNA and possess type I IGF receptors. Ref El-Badry OM, et al. Autonomous growth of a human neuroblastoma cell line is mediated by insulin-like growth factor II. J. Clin. Invest. 84: 829-839, 1989. PubMed: 2547840 Retinoic acid partially inhibits proliferation, and cells fail to differentiate. Ref Gaetano C, et al. Retinoic acid negatively regulates p34cdc2 expression during human neuroblastoma differentiation. Cell Growth Differ. 2: 487-493, 1991. PubMed: 1751405 The cells exhibit low or no MDR1 expression. |
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:
- O.1 mM Non-Essential Amino Acids (NEAA)
- 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-0.53 mM EDTA solution to remove all traces of serum that 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.
Subculture Ratio: 1:5 to 1:10
Medium Renewal: 2 to 3 times a week.
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.
