Figure 1From: 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 human annulus. (a) Positive identification of thrombospondin-2 (TSP-2) is present in some cells in the outer annulus. (b) Localization was also positive for cells in the inner annulus, including cells present in clusters. (c) Adjacent section processed in the absence of antibody as a negative control.
