From: Increased caveolin-1 in intervertebral disc degeneration facilitates repair
Disialoganglioside 2 (GD2) and Tie2 expression is increased in caveolin-1 (Cav-1)-null mice. Immunofluorescent staining for Cav-1 (red), GD2 (green), and Tie2 (red) on the nucleus pulposus of wild-type (WT) and Cav-1-null mice. The cell nuclei were stained with 4′,6-diamidino-2-phenylindole (blue). Bars indicate 25 μm. n = 2–5 per age group and condition (WT or Cav-1-null mice)
