Cell proliferation and programmed cell death (PCD) are key to tooth development, working together to shape the growing tooth structure. These processes are active in early tooth bud, cap, and bell stages.

Area of Science:

  • Developmental Biology
  • Cell Biology

Context:

  • Tooth development is a complex process involving coordinated cell activities.
  • Understanding the roles of cell proliferation and programmed cell death (PCD) is crucial for comprehending tooth morphogenesis.

Purpose:

  • To investigate the interplay between cell proliferation and PCD during tooth development.
  • To detect the expression of proliferating cell nuclear antigen (PCNA) and PCD in various tooth development stages.

Summary:

  • Immunohistochemistry and TUNEL assays revealed PCNA and PCD expression in proliferating centers during bud, cap, and bell stages of rat tooth development.
  • These cellular events were also observed in ameloblasts, odontoblasts, stellate reticulum cells, and dental papilla during dentinogenesis.

Impact:
