| Outline of Final Research Achievements |
Porous scaffolds with micropatterned structures are a promising tool for the regeneration of functional tissues, because they can mimic the biological and physiochemical factors in the in vivo cell microenvironments. Here we developed a method to micropattern bioactive molecules in porous collagen scaffolds by the combination of dispensing technique and freeze drying. Frozen micropatterns of the mixture of collagen and bioactive molecules solutions were used as templates to introduce bioactive molecules into the porous scaffolds. The distribution of bioactive molecules was spatially controlled by the micropatterns tethered by designing a computer program. The micropatterned porous scaffolds will be useful for spatially guided tissue regeneration.
