Abstract:
1. A scaffold that is formed in a lattice form by alternately stacking a plurality of biodegradable synthetic polymer-hydrogel layers wherein after one biodegradable synthetic polymer-hydrogel layer is stacked, the next biodegradable synthetic polymer-hydrogel layer is stacked by rotating the next biodegradable synthetic polymer-hydrogel layer by 90 degrees to form a lattice pattern, wherein each of the biodegradable synthetic polymer-hydrogel layers is formed by disposing a plurality of biodegradable synthetic polymer-hydrogel units spaced apart from each other at a pre-determined gap, each of the plurality of biodegradable synthetic polymer-hydrogel units comprises a biodegradable synthetic polymer and a hydrogel, wherein each of the plurality of biodegradable synthetic polymer-hydrogel units is formed by interposing a single hydrogel line between a pair of a plurality of biodegradable synthetic polymer lines stacked upon each other and fusing the single hydrogel line and the pair of the stacked plurality of biodegradable synthetic polymer lines.
