Bmal1 deletion alters the balance of fibroblasts and chondrocytes within joints. a Flow cytometric analysis of the cellular composition of the joints from wild-type (n = 9) and Col6a1-Bmal1^−/− (n = 12) mice (aged 9–18 weeks) after exclusion of doublets and dead cells. Analysis by unpaired t test. b Expression of chondrocyte-associated genes in the hind limbs of mice, aged 10 weeks (n = 4). Analysis by unpaired t test
