Key Event Description
Post-migratory cranial NCCs differentiate to give rise to chondrocytes which secrete collagen in order to form the cartilage structures which form the precursors of bony facial features (Bhatt et al., 2013).
How It Is Measured or Detected
Collagen expression is considered a marker for NCC differentiation into chondrocytes (Bhatt et al., 2013) and can be assessed in vivo by fluorescent microscopy using fluorescent collagen reporter zebrafish lines (Hammond and Schulte-Merker, 2009).
