20230103452 · 2023-04-06 ·

A system and method for tissue fabrication involves the use of charge manipulation between two biomaterials to generate a shrinking response, which effectively enhances the resolution of bioprinted hydrogels. The charge manipulation can be utilized to generate tissue engineered thin, membranous tissues, such as the periosteum, which is approximately one hundred microns in thickness. Thin membranous tissues in the body also have relatively complex anatomies containing multiple cell populations, and no prior strategies allow for the effective and biomimetic generation of these tissues, which can have significant impact on tissue regeneration.

Bone gel sheet composition and method of manufacture

A bone gel composition consists of cortical bone. The cortical bone is made from cut pieces freeze-dried then ground into particles and demineralized then freeze-dried.
