Towards organ printing: engineering an intra-organ branched vascular tree

3D Organ Printing

Organ printing: computer-aided jet-based 3D tissue engineering.

Tissue engineering technology promises to solve the organ transplantation crisis. However, assembly of vascularized 3D soft organs remains a big challenge. Organ printing, which we define as computer-aided, jet-based 3D tissue-engineering of living human organs, offers a possible solution. Organ printing involves three sequential steps: pre-processing or development of "blueprints" for organs; ...

Organ printing: fiction or science.

Aggregates of living cells (i.e. model tissue fragments) under appropriate conditions fuse like liquid drops. According to Steinberg's differential adhesion hypothesis (DAH), this may be understood by assuming that cells are motile and tissues made of such cells possess an effective surface tension. Here we show that based on these properties three-dimensional cellular structures of prescribed ...

Dimensional 3 - D Printing in Organ Transplantation

An insufficient supply of organs for transplant is an ever present obstacle for transplant medicine. A long term resolution of these problems is being sought by developing ways to engineer live organs from a person’s own cells. Previous tissue manufacturing approaches involved seeding either adult or stem cells onto various 3D scaffolds, with subsequent cell proliferation and differentiation in...
