Applications:These cell lines are good models for studying in vitro osteoblast differentiation, particularly ECM signaling.
The MC3T3 Subclone 24 (ATCC CRL-2595 ) and the MC3T3 Subclone 30 (ATCC CRL-2596 ) lines exhibit poor osteoblast differentiation after growth in ascorbic acid.
Tumorigenic:Yes
Age: newborn
Comments:A series of subclones were isolated from the cloned but phenotypically heterogeneous MC3T3-E1 cell line.
The subclones were selected for high or low osteoblast differentiation and mineralization after growth in medium containing ascorbic acid.
The MC3T3-E1 Subclone 4 (ATCC CRL-2593 ) and the MC3T3 Subclone 14 (ATCC CRL-2594 ) lines exhibit high levels of osteoblast differentiation after growth in ascorbic acid and 3 to 4 mM inorganic phosphate. [51540 ]
They form a well mineralized extracellular matrix (ECM) after 10 days.
The MC3T3 Subclone 24 (ATCC CRL-2595 ) and the MC3T3 Subclone 30 (ATCC CRL-2596 ) lines exhibit poor osteoblast differentiation after growth in ascorbic acid. They do not form ECM. They can be used as negative controls for Subclones 4 and 14. [51540 ]
Mineralizing subclones selectively express mRNAs for the osteoblast markers, bone sialoprotein (BSP), osteocalcin (OCN), and the parathyroid hormone (PTH)/parathyroid hormone-related protein (PTHrP) receptor. [51540 ]
Subclones with both high and low differentiation potential produce similar amounts of collagen in culture and express comparable basal levels of mRNA encoding Osf2/Cbfa1, an osteoblast-related transcription factor. [51540 ]
After implantation into immunodeficient mice, highly differentiating subclones form bone-like ossicles resembling woven bone, while poorly differentiating cells only produce fibrous tissue. [51540 ]
These cell lines are good models for studying in vitro osteoblast differentiation, particularly ECM signaling. They have behavior similar to primary calvarial osteoblasts.
Propagation: ATCC complete growth medium: The base medium for this cell line is Alpha Minimum Essential Medium with ribonucleosides, deoxyribonucleosides, 2 mM L-glutamine and 1 mM sodium pyruvate, but without ascorbic acid (GIBCO, Custom Product, Catalog No. A1049001). To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C
Subculturing: Protocol: Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37°C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:6 is recommended
Medium Renewal: Every 2 to 3 days
Preservation: Freeze medium: Complete growth medium 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
