Overview

Narrative review outlines cellular mechanisms driving longitudinal bone growth via growth plate chondrocytes, highlighting how proliferation and hypertrophy respond to regulatory signals.

Key Points

  • To review cellular processes underlying longitudinal bone lengthening, focusing on the distinct roles and regulation of growth plate chondrocytes throughout their life cycle.
  • Surveyed cellular phenomena driving longitudinal bone elongation with a focus on epiphyseal plate chondrocytes in vivo.
  • Assessed the relative contributions of chondrocyte proliferation and cell hypertrophy alongside their modulation by growth-promoting factors.
  • Chondrocyte proliferation and hypertrophic cell enlargement serve as the primary cellular drivers of longitudinal bone elongation.
  • The relative contributions of proliferation and hypertrophy shift dynamically to accommodate specific developmental demands across distinct growth phases.
  • Growth-promoting substances direct epiphyseal chondrocyte activities to precisely modulate the rate and extent of skeletal elongation.
