This volume provides an updated collection of protocols for manipulating and studying VEGF signaling pathways in vitro and in vivo and aims to present a range of both firmly established and newly emerging technologies. Covering multiple model species, from mouse to zebrafish to human, the book explores the role of VEGF and VEGFR isoforms in exosomes, cultured cells, or in tissues, as well as robust cell assays for the investigation of basic angiogenic mechanisms and VEGF signaling in more complex cellular systems, amongst other subjects. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
