|---|---|
| 商品貨號 | B162184 |
| Organism | Mus musculus, mouse |
| Tissue | bone, calvaria |
| Cell Type | preosteoblast |
| Product Format | frozen |
| Morphology | fibroblast |
| Culture Properties | adherent |
| Biosafety Level | 1
Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Age | newborn |
| Strain | C57BL/6 |
| Applications | These cell lines are good models for studying in vitro osteoblast differentiation, particularly ECM signaling. They have behavior similar to primary calvarial osteoblasts. |
| Storage Conditions | liquid nitrogen vapor phase |
| Derivation | A series of subclones were isolated from the cloned but phenotypically heterogeneous MC3T3-E1 cell line. |
| Genes Expressed | collagen

| Tumorigenic | Yes |
| Effects | Yes, in immunodeficient mice (forms bone-like ossicles) |
| Comments | 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. 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.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. 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.
After implantation into immunodeficient mice, highly differentiating subclones form bone-like ossicles resembling woven bone, while poorly differentiating cells only produce fibrous tissue. |
| 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%.
|
| 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.
Subculture Ratio: 1:6 to 1:8 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
