Fig. 2: The number of autophagosomes/autolysosomes in osteoclasts is decreased in GIT1 KO mice.

a Representative transmission electron microscopy (TEM) images of osteoclasts from the femur fracture model of GIT1 WT and GIT1 KO mice on days 21 and 28 post-fracture. Black arrows indicate autophagosomes/autolysosomes. Scale bars = 5 μm. b The number of autophagosomes/autolysosomes in GIT1 WT and GIT1 KO mice on days 21 and 28 during fracture repair (values are means ± SD, **p < 0.01, two-tailed Student's t-tests)
