Figure 2From: Disruption of the thrombospondin-2 gene alters the lamellar morphology but does not permit vascularization of the adult mouse lumbar discLocation of thrombospondin-1 in the annulus of the mouse intervertebral disc. Dark-stained cells show localization of thrombospondin-1 (TSP-1) in (a) the outer annulus of wild-type (WT) mice and (b) the annulus adjacent to the central portion of the nucleus pulposus. (c) Negative control. Magnification, ×300.Back to article page
