VEGFA and neurodegenerative disease: It has been shown that CBP contains high amounts of various growth factors, such as vascular endothelial growth factor (VEGF), insulin‐like growth factor‐1 and transforming growth factor (TGF)‐β, that are required for cell maintenance during hematopoiesis.3, 12 Although CBP can exert a favourable effect on hematopoietic stem cells, whether CBP elicits therapeutic benefit as an additive to, or substitute for, cells must be determined before developing clinically relevant CBP‐based therapies for various neurodegenerative diseases.
