Collapsin response mediator protein family: Collapsin response mediator protein family or CRMP family consists of five intracellular phosphoproteins (CRMP-1, CRMP-2, CRMP-3, CRMP4, CRMP5) of similar molecular size (60–66 kDa) and high (50–70%) amino acid sequence identity. CRMPs are predominantly expressed in the nervous system during development and play important roles in axon formation from neurites and in growth cone guidance and collapse through their interactions with microtubules.Vascular endothelial growth factor (VEGF) IRES ANeuropilinSemaphorin: Semaphorins are a class of secreted and membrane proteins that act as axonal growth cone guidance molecules. They primarily act as short-range inhibitory signals and signal through multimeric receptor complexes.Lymphokine: Lymphokines are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte. They are protein mediators typically produced by T cells to direct the immune system response by signalling between its cells.Soluble fms-like tyrosine kinase-1Axon guidance: Axon guidance (also called axon pathfinding) is a subfield of neural development concerning the process by which neurons send out axons to reach the correct targets. Axons often follow very precise paths in the nervous system, and how they manage to find their way so accurately is being researched.TuftsinVasculogenesis: Vasculogenesis is the process of blood vessel formation occurring by a de novo production of endothelial cells.Cranial nerve examinationRelated to receptor tyrosine kinase: The related to receptor tyrosine kinase (RYK) gene encodes the protein Ryk.Endothelial progenitor cell: Endothelial progenitor cell (or EPC) is a term that has been applied to multiple different cell types that play roles in the regeneration of the endothelial lining of blood vessels. Despite the history and controversy, the EPC in all its forms remains a promising target of regenerative medicine research.
