Models to investigate intussusceptive angiogenesis: A special note on CRISPR/Cas9 based system in zebrafish

Abstract

Angiogenesis is a distinct process which follows sprouting angiogenesis (SA) and intussusceptive angiogenesis (IA) forming the basis for various physiological and pathological scenarios. Angiogenesis is a double edged sword exerting both desirable and discernible effects owing to the referred microenvironment. Therapeutic interventions to promote angiogenesis in regenerative medicine is essential to achieve functional syncytium of tissue constructs while, angiogenic inhibition is a key therapeutic target to suppress tumor growth. In the recent years, clustered regularly interspaced short palindromic repeats associated 9 (CRISPR-Cas9) based gene editing approaches have been gaining considerable attention in the field of biomedical research owing to its ease in tailoring targeted genome in living organisms. The Zebrafish model, with adequately high-throughput fitness, is a likely option for genome editing and angiogenesis research. In this review, we focus on the implication of Zebrafish as a model to study IA and furthermore enumerate CRISPR/Cas9 based genome editing in Zebrafish as a candidate for modeling different types of angiogenesis and support its candidature as a model organism.
