Figure 3From: Disruption of the thrombospondin-2 gene alters the lamellar morphology but does not permit vascularization of the adult mouse lumbar discLocation of thrombospondin-2 in the mouse annulus. (a) Thrombospondin-2 (TSP-2) is present in many cells in the annulus of wild-type (WT) mice. (b) TSP-2 is absent in cells of the annulus in TSP-2-null mice. (c) Negative control processed in the absence of primary antibody. Magnification, ×300.Back to article page
