BACKGROUND English ivy (Hedera helix) is well known for its adhesive properties and climbing ability. Essential to its ability to adhere to vertical surfaces is the secretion of a nanocomposite adhesive containing spherical nanoparticles, 60-85 nm in diameter, produced exclusively by root hairs present on adventitious roots. These organic nanoparticles have shown promise in biomedical and cosme...
The behavior of tissue fragments in permissive jells is like liquid drops. Under appropriate conditions this phenomenon could be used to print tissues of prescribed shape. Application of the principles of rapid prototyping to tissue engineering or robotic biofabrication is a novel technology that holds promising future in producing suitable human organs in large scale. An introductory discussio...
We report a facile method to fabricate free-standing, 3D hydrogel microarchitectures of chemically sol-gel transitional hydrogels, which is based on the use of hydrophilic substrate and aerosol of gelling agent without molding (or sandwiching) process. Using proposed methods, we fabricated hydrogel microarchitectures of sheets, meshes, or microunits without morphological distortions on the micr...
In Vitro Generation of Pancreatic Pseudo-islets Using Free-standing Mesh Patterned Cellular Hydrogel
This paper reports a simple and direct method to fabricate mesoscopic hydrogel constructs for size controlled pseudo-islets with MIN6 cells, a pancreatic β-cell insulinoma, via lamination of free-standing mesh patterned cellular hydrogel. The MIN6-laden hydrogels with three different micro-patterns were simply fabricated, free-standing cultured, and functionally analyzed to examine the effect o...
Adult tissue stem cells can form self-organizing 3D organoids in vitro. Organoids resemble small units of their organ of origin and have great potential for tissue engineering, as well as models of disease. However, current culture technology limits the size, architecture and complexity of organoids. Here, we review the establishment of intestinal and hepatic organoids and discuss how the conve...
