Conditional deletion of Bmal1 in Col2a1-expressing cells results in disruption of the circadian rhythms in mouse intervertebral discs (IVDs). (A) IHC of BMAL1 in 3-month-old wild type (WT) and KO mice (magnification: upper panels 10× and lower panels 40×); n=3. (B) Representative bioluminescence traces of WT (blue) and Bmal1 cKO (red) mouse IVD explant cultures; n=6. Arrow indicates treatment with dexamethasone. (C) Live bioluminescence imaging of IVDs from WT and Bmal1 cKO IVDs from mice on a PER2::Luc background.
