Figure 4From: Disruption of the thrombospondin-2 gene alters the lamellar morphology but does not permit vascularization of the adult mouse lumbar discMorphologic features of wild-type and thrombospondin-2-null mouse ventral annuli. The morphologic features of the (a) wild-type (WT) mouse ventral annuli and (b) thrombospondin-2-null mouse ventral annuli are similar. Masson-trichrome stain, magnification, ×300.Back to article page
