| Product description: | A conditionally immortal cell line derived from the mouse cochlea. The immortalising gene was activated in organotypic cultures of auditory sensory epithelia at E13, the thirteenth day of embryonic development, before the hair cells had started to differentiate after their last mitoses. The cell line expresses characteristic hair cell markers including the transcription factor Brn3.1, the a9 subunit of the acetylcholine receptor, the stereociliary protein fimbrin and the myosins VI and VIIA. UB/OC-2 cells have higher expression of Brn3.1, the a9AChR and myosin VIIa compared with UB/OC-1 at 33°C suggests that the former may have been immortalized at a later stage of differentiation and therefore represent committed hair cell precursors. This means that UB/OC-2 can be used specifically to study hair cell development at an early stage. At this stage they do not display the hair cell phenotype (cuticular plate, stereocilia, polarised organisation, etc.), but do express proteins specific to the hair cell transduction apparatus. |
| Alternate name: | Organ of Corti cell line number 2; UB/OC-2 |
| Conditional: | Yes |
| Conditional description: | Proliferating cultures at 33°C in the presence of γIF and differentiating cultures at 39°C in the absence of γIF due to the temperature sensitivity of the immortalising gene regulated by a γ-interferoninducible promoter |
| Production details: | Cells derived from C57/Bl6 mice carrying a stable insertion of the conditional immortalising gene H-2Kb-tsA58, which describes a temperature-sensitive variant of the SV40 immortalising gene that encodes the large tumour antigen under the control of the Î?âinterferon-sensitive MHC Class 1 promoter. The transgenic mouse is called the Immortomouseâ? (Jat et al 1991 Proc. Nat. Acad. Sci. USA 88, 5096-5100) |
