MC3T3-E1 Cell Line

General Information
OrganismMus musculus, mouse
Cell Line DescriptionThe osteoblastic cell line MC3T3-E1 was established from C57BL/6 mouse calvaria and selected based on high alkaline phosphatase (ALP) activity at rest. The cells can differentiate into osteoblasts and osteocytes and have been shown to form calcified bone tissue in vitro. The mineral deposit has been identified as hydroxyapatite. Basic fibroblast growth factor (bFGF) mRNA and protein expression is modulated by TGF beta and bFGF treatment. Prostaglandin F2a has been reported to stimulate DNA synthesis and proliferation through upregulation of insulin-like growth factor I receptors. MC3T3-E1 secretes collagen and expresses murine leukemia inhibitory factor (mLIF) in RNA. Contact inhibition is a natural process that prevents cell growth when cells come into contact with each other.

Additional InfoIt cannot be determined how the loss of contact inhibition affects other properties of the MC3T3-E1 cell line. This cell line catalog number remains a popular choice. A key consideration is whether the intended use of the cell line requires contact inhibitory properties. For example, it is required when testing the effects of potential oncogene expression (where induction of loss of contact inhibition is being measured), whereas it is less relevant when using cell lines expressing recombinant proteins for production and purification.

Culture Conditions and Handling
Subculturing1. Remove and discard the culture medium.
2. Briefly rinse the cell layer with a 0.25% (w/v) trypsin-0.53 mM EDTA solution to remove all traces of serum containing trypsin inhibitors.
3. Add 2.0 to 3.0 mL of trypsin-EDTA solution to the flask and observe the cells under an inverted microscope until the cell layer is dispersed (usually within 5 to 15 minutes). NOTE: To avoid clumping, do not agitate the cells by knocking or shaking the flask while waiting for cells to detach. Cells that are difficult to separate can be placed at 37°C to facilitate dispersion.
4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gentle pipetting.
5. Add appropriate aliquots of cell suspension to new culture vessels.
6. Incubate cultures at 37°C.
NOTE: The volumes used in this protocol are for a 75 cm2 flask. For other sizes of culture vessels, proportionally reduce or increase the amount of dissociation medium.
Medium RenewalEvery 2 to 3 days
Subcultivation RatioThe ratio of 1:3 to 1:5 is recommended.
Culture MediumMEM alpha + 2mM Glutamine + 10% Foetal Bovine Serum (FBS)
