| Clinical Data |
male |
| Antigen Expression |
H-Y antigen; Mus musculus, expressed |
| Receptor Expression |
follicle stimulating hormone (FSH), expressed androgen receptor, expressed progesterone receptor, expressed |
| Genes Expressed |
retinol binding protein, tissue plasminogen activator, transferrin |
| Tumorigenic |
No |
| Effects |
No, The cells were not tumorigenic in immunosuppressed mice, but did form colonies in semisolid medium. |
| Comments |
The TM4 cell line is reported to respond to FSH with an increase in cAMP production, but to not respond to luteinizing hormone (LH). The FSH responsiveness is much reduced compared to primary sertoli cell cultures. Constitutive plasminogen activator production is reported to be low, but is stimulated by FSH and, to a greater extent, by retinoic acid. Tested and found negative for ectromelia virus (mousepox). |
| Complete Growth Medium |
A 1:1 mixture of Ham'S F12 medium and Dulbecco's modified Eagle's medium with 1.2 g/L sodium bicarbonate and 15 mM HEPES, 92.5%; horse serum, 5%; fetal bovine serum, 2.5%
|
| Subculturing |
Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally 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 which 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 supension to new culture vessels.
- Incubate cultures at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:10 to 1:50 is recommended
