In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs). Later, notochordal cells (NCs) mature and adopt a characteristic vacuolated morphology before giving rise to the core of the forming IVD, the nucleus pulposus (NP). Postnatally, NCs play a pivotal role in maintaining disc integrity through the secretion of specific factors and extracellular matrix (ECM). Despite its importance in disc formation and homeostasis, the morphogenetic mechanisms underlying the notochord's transformation into the NP are insufficiently characterized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We conducted a comprehensive histological and immunohistochemical analysis to investigate the cellular events governing NP formation in the mouse developing spine.

In addition, quantitative analyses demonstrated a notable proliferative capacity within notochordal cells coupled with region\u2010specific apoptotic activity in sclerotome, at future disc sites.\n
