Figure 5From: Ossification process involving the human thoracic ligamentum flavum: role of transcription factors Immunostaining for Sox9, Runx2, and Msx2 of the OLF. Sox9 (a) was expressed in proliferating chondrocytes. Runx2 (b) was expressed in hypertrophic chondrocytes. Msx2 (c) was expressed in proliferating chondrocytes (scale bar = 100 μm; n.c., negative control; black arrow, hypertrophic chondrocytes; black arrowheads, proliferating chondrocytes).Back to article page
