Higher tibial vascular distribution in the hypertrophic chondrocyte zones of TBCs. (a) Tibial vascular distribution was significantly increased in TBCs compared to AACs. The arrows indicate BVs (blood vessels); RZ, resting chondrocyte zone; PZ, proliferative chondrocyte zone; HZ, hypertrophic chondrocyte zone; and TB, trabecular bone. Scale bar = 500 µm. (b,c) The relative BV area and BV number were determined from two isolated groups using Image-Pro® Plus 6.0. Student’s t-test, * p < 0.05, ** p < 0.01, *** p < 0.001, n = 6; Error bars indicate SD. ns, not significant. AAC, Arbor Acres chicken; TBC, Tibetan chicken.
