| Research Abstract |
We analyzed the CYP26B1 conditional knockout mice driven by cartilage precursor specific Cre. The mice were normally born, but revealed severe growth impairment at three or four weeks after birth. The facial bone was rounder and smaller in shape, including the deficiency of dental occlusion caused by the imbalance between the maxilla and the mandible. The decrease of chondrocytes in the growth plate resembled a phenotype of complications induced by retinoid therapy, which was thought to be clinically important.
