Notochord nucleus pulposus cells are characteristic of containing abundant and
giant cytoplasmic vacuoles. This review explores the embryonic formation,
biological function, and postnatal exhaustion of notochord vacuoles, aiming to
characterize the signal network transforming the vacuolated nucleus pulposus
cells into the vacuole-less chondrocytic cells. Embryonically, the cytoplasmic
vacuoles within vertebrate notochord originate from an evolutionarily conserved
vacuolation process during neurulation, which may continue to provide mechanical
and signal support in constructing a mammalian intervertebral disc. For full
vacuolation, a vacuolating specification from dorsal organizer cells,
synchronized convergent extension, well-structured notochord sheath, and
sufficient post-Golgi trafficking in notochord cells are required. Postnatally,
age-related and species-specific exhaustion of vacuolated nucleus pulposus cells
could be potentiated by Fas- and Fas ligand-induced apoptosis, intolerance to
mechanical stress and nutrient deficiency, vacuole-mediated proliferation check,
and gradual de-vacuolation within the avascular and compression-loaded
intervertebral disc. These results suggest that the notochord vacuoles are active
and versatile organelles for both embryonic notochord and postnatal nucleus
pulposus, and may provide novel information on intervertebral disc degeneration
to guide cell-based regeneration.
