Title: Migration of Cells


1
Migration of Cells
2
Migration of PGCs
  • Migration of primordial germ cells in mice
    involves Receptor Tyrosine Kinase (RTK) cKit
  • Ligand for cKit is Mgf

Some Neural Crest Derivatives
  • Pigment cells (melanocytes)
  • Sensory, sympathetic and parasympathetic nervous
    system
  • Endocrine tissue (adrenal medulla)
  • Skeletal and connective tissue

Migration of Neural Crest
  • May be guided by Eph/Ephrin system
  • Eph receptors are RTKs
  • Ephrins are ligands that are bound to cells
