bioartificial organ

bioartificial organ

An implanted synthetic device designed to replace the function of a failing organ—e.g., liver cells housed in a synthetic hollow-fibre dialysis cartridge, allowing donor-cell contact with host fluids, while preventing donor-antigen contact with the host immune system, thereby minimising rejection.

"A continuous supply of oxygen is needed from the time that the cells are first isolated from a donor pancreas until the bioartificial organ is implanted and develops its own blood vessels, typically five to 10 days post-transplant," said Opara.
They can be used for many biotech applications including bioartificial organ development.

Vladimir Vasilets is head researcher at the Federal Scientific Research Centre of Transplantology and Bioartificial organs in Moscow.
When methods to cryopreserve complex tissues are perfected, it will become possible to store virtually every tissue in the body--whether taken from human donors, grown in the laboratory from stem cells, or combined with artificial components to form bioartificial organs. Such banks will be used to cure diseased or severely injured patients and to reverse aging in humans.
of Toledo) introduces the fundamental engineering and life science principles relevant to chemical and physical transport processes with applications towards the development of artificial organs, bioartificial organs, controlled drug delivery systems, and tissue engineering.
For example, polymer cell encapsulation promises immunoisolation, which has initiated a flurry of research into bioartificial organs. Prospect of polymer encapsulation increasing long-term in vivo cell survivability has opened new avenues for both targeted and recurrent therapeutic drug delivery systems.

The development of bioartificial organs has been facilitated primarily by the ability of cell encapsulation technology to isolate foreign cells from a host immune response.
While this integration of islets into the liver may limit both the maximal size of implantable islets and their development as discrete bioartificial organs, the concept of administering fibrosis-inhibiting drugs to endogenous cells surrounding an implanted capsule could represent a promising future direction of research.
