Fig. 7From: Cartilage-specific deletion of ephrin-B2 in mice results in early developmental defects and an osteoarthritis-like phenotype during aging in vivoSome ephrin-B2 (EFNB2)Col2knockout (KO) cartilage conditional mice exhibited a locomotor phenotype. EFNB2fl/fl (a, b) and about 27Â % of the EFNB2Col2KO cartilage conditional mice (c-e) demonstrated a locomotor phenotype consisting of dragging and limping as soon as they started to walk. Additional movie files show the locomotor phenotype in more detail (see Additional file 1 (EFNB2fl/fl) and Additional file 2 (EFNB2Col2KO))Back to article page
