Tool Details

*FOR RESEARCH USE ONLY

  • Name: UB-OC1 Cell Line
  • Alternate name: Organ of Corti cell line number 1; UB/OC-1
  • Research fields: Developmental biology;Drug development;Genetics
  • Tool sub type: Continuous
  • Parental cell: Primary cultures of the developing organs of Corti of E13 embryonic Immortomouse TM
  • Organism: Mouse
  • Tissue: Developing organs of Corti
  • Disease: Hearing loss
  • Model: Conditionally immortalised
  • Conditional: Yes
  • Conditional description: Proliferating cultures at 33°C in the presence of yIF and differentiating cultures at 39°C in the absence of yIF due to the temperature sensitivity of the immortalising gene regulated by a y-interferoninducible promoter
  • Description: A conditionally immortal cell line derived from the mouse cochlea. The immortalizing 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. The relatively low expression of Brn3.1, the a9AChR and myosin VIIa in UB/OC-1 compared with UB/OC-2 at 33°C suggests that the former may have been immortalized at an earlier stage of differentiation. UB/OC-1 probably originates from the nonsensory epithelial cell population in the GER and, when differentiated, closely resembles the hair cell phenotype. Thus it has considerable potential for studying the genetic processes underlying a potential mechanism for recruitment of replacement hair cells.
  • Application: Inner ear development studies; Gene expression and functional studies of inner ear-specific genes; In vitro screening for gene activation and promoter analysis; Ototoxicity studies (prescribed drugs and agents that ameliorate their affects); Functional studies of inherited deafness mutations
  • 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 y–interferon-sensitive MHC Class 1 promoter. The transgenic mouse is called the Immortomouse TM (Jat et al 1991 Proc. Nat. Acad. Sci. USA 88, 5096-5100)
