Functional bio-ink composition comprising vascular endothelial growth factor for inducing angiogenesis

摘要

The present invention relates to a functional bio-ink composition comprising a vascular endothelial growth factor (VEGF) for inducing angiogenesis, and more particularly, to a bio-ink composition comprising VEGF which has cytocompatibility, high viscosity and elasticity for easy printing, excellent structural stability, and appropriate mechanical properties after printing, thereby having an excellent effect of inducing angiogenesis. The bio-ink composition of the present invention shows an effect of promoting angiogenesis along with high visco-elasticity, strong structural stability, and excellent printability, biocompatibility and mechanical properties after printing, and thus may be very valuably used in preparing tissue-like organs and treating tissue damage, etc., by using a three-dimensional bio-printing.
