Overview

Pharmacological inhibition of csf1r signaling disrupts neural crest proliferation and craniofacial development.

Key Points

  • Depletion of csf1r+ macrophages and osteoclasts impaired craniofacial morphogenesis, affecting skull shape.
  • Prenatal exposure to PLX5622 reduced csf1r+ macrophages by about 50% and eliminated osteoclasts.
  • Changes in cytokine and chemokine signaling indicate that csf1r+ macrophages play critical roles in neural crest proliferation.
  • Observation of strain-specific differences highlights the complex interaction in craniofacial development success.
