| abstract |
The present invention relates to a bio-ink composition having improved physical and biological properties and, more specifically, to a bio-ink composition, which exhibits, through a combination of specific contents of components, high viscosity, strong shear-thinning tendencies, formations of fast cross linkages, and appropriate mechanical properties after printing. The bio-ink composition of the present invention is capable of being used very usefully in the preparation of three-dimensional bio-printed tissue-like organs and internal transplantable tissue structures. |
