This line was derived from minced, trypsinized Swiss mouse embryos grown in serum free medium.
Disclosure This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC.
Karyotype modal number = 40; range = 39 to 42
This line was derived from minced, trypsinized Swiss mouse embryos grown in serum free medium.
Tumorigenic No
No, The cells were not tumorigenic in immunosuppressed mice, but did form colonies in semisolid medium.
This line was derived from minced, trypsinized Swiss mouse embryos grown in serum free medium.
BALB/c SFME cells infrequently form colonies in soft agar and are not tumorigenic if injected into nude mice.
Either serum or TGF-beta induce astrocyte differentiation accompanied by GFAP (glial fibrillary acidic protein) expression. Furthermore, the presence of serum causes cell growth arrest.
This process is reversible upon removal of the serum.
Swiss SFME cells do not grow in conventional media supplemented with fetal bovine serum or bovine calf serum.
When cultured in the serum free medium (see below), Swiss SFME cells reportedly can be propagated for extended periods without undergoing"crisis" or gross chromosomal aberration.
Complete Growth Medium Dulbecco's modified Eagle's medium with 4.5 g/L glucose, 50%; Ham's F12 medium, 50%, Supplements: 0.01 mg/ml bovine insulin, 0.025 mg/ml human transferrin, 0.02 mg/ml human high density lipoprotein (HDL), 100 ng/ml mouse epidermal growth factor (EGF), 10 nM sodium selenite, 1 unit/ml human platelet derived growth factor (PDGF), and 15 mM HEPES. NOTE: HDL is available from Sigma Chemical Co. (catalog number L2014).
Subcultivation Ratio: A subcultivation ratio of 1:10 to 1:100 is recommended
Medium Renewal: Twice per week
Remove medium, and collect suspended clusters by centrifugation.
To disperse clusters or to remove adherent cells, add fresh 0.25% Trypsin, 0.02% EDTA at room temperature until the cells disperse (2 to 3 minutes).
Add an equal volume of fresh serum free medium plus 0.1% soybean trypsin inhibitor and centrifuge at 1000 X g.
Resuspend the cell pellet in growth medium, aspirate and dispense into new (fibronectin coated, if adherence is desired) flasks.
Floating clusters may also be remove using a pipette and transferred to a flask containing fresh growth medium.
culture medium, 80%; fetal bovine serum, 10%; DMSO, 10%
