Artificial Blood Vessels Developed in the Lab Can Grow with the Recipient
In a groundbreaking new study led by University of Minnesota biomedical engineers, artificial blood vessels bioengineered in the lab and implanted in young lambs are capable of growth within the recipient. If confirmed in humans, these new vessel grafts would prevent the need for repeated surgeries in some children with congenital heart defects.
In this study, University of Minnesota Department of Biomedical Engineering Professor Robert Tranquillo and his colleagues generated vessel-like tubes in the lab from a post-natal donor’s skin cells and then removed the cells to minimize the chance of rejection. This also means the vessels can be stored and implanted when they are needed, without the need for customized cell growth of the recipient. When implanted in a lamb, the tube was then repopulated by the recipient’s own cells allowing it to grow.

Immunostaining for cell markers in the bioengineered graft showed recellularization across the entire thickness and length of the grafts.

ReplyDeleteNext step would be to grow the entire heart, perhaps using the patients' own stem cells to minimise rejection. Could an X-Ray or MRI be used to create a 1-1 replica of our organs, grown on a 3D printed mould of some sort? I bet some old, rich billionaires somewhere look at things like this with interest, or even younger ones not wanting to get old
