| Comments: | The 15P-1 cell line was established from testicular cells of transgenic mice that express the large T protein of polyoma virus (PyLT) in the seminiferous epithelium. [53202 ] This line exhibits characteristics of Sertoli cells, including transcription of the Wilms' tumor (WT1) and Steel genes. [53203 ] 15P-1 cultures express phagocytic activity evidenced by the internalization of latex beads and the disposal of dead cells. Interaction with germ cells enhances the phagocytic activity of 15P-1 cells. [53204 ] The cells support the meiotic and postmeiotic differentiation in cocultures of diploid premeiotic germ cells into haploid spermatids expressing the protamine (Prm-1) gene. [53203 ] When cocultured with 15P-1 cells, testicular cells explanted from immature 9-day-old animals, before the onset of the first meiosis, generate tetrads of haploid cells with the morphology of round spermatids and initiate protamine transcription. [53203 ] The 15P-1 cell line releases protease-sensitive material with broad-spectrum antibacterial activity. The activity of 15P-1 culture medium is increased 10-fold to 50-fold in the presence of fractions enriched in round spermatids and of nerve growth factor. [53205 ] The KL protein, a ligand of the Kit receptor, is expressed in Sertoli cells and in 15P-1 cells. [53206 ] |

| Propagation: | ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. Temperature: 32.0°C |
||
| Subculturing: | Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended Medium Renewal: Twice per week 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 37C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks. Do not inoculate new flasks at cell densities below 1 X 10 exp4 cells per sq. cm. |
