| Derivation： | 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.Ref   Paquis-Flucklinger V, et al. Expression in transgenic mice of the large T antigen of polyomavirus induces Sertoli cell tumours and allows the establishment of differentiated cell lines. Oncogene 8: 2087-2094, 1993.

| 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. Ref This line exhibits characteristics of Sertoli cells, including transcription of the Wilms tumor (WT1) and Steel genes.xa0Ref 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.xa0Ref The cells support the meiotic and postmeiotic differentiation in cocultures of diploid premeiotic germ cells into haploid spermatids expressing the protamine (Prm-1) gene.xa0Ref 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. Ref 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.xa0Ref The KL protein, a ligand of the Kit receptor, is expressed in Sertoli cells and in 15P-1 cells.xa0Ref |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Dulbeccos Modified Eagles 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%.
