Stem Cells Stimulate Regeneration of Vascular Tissue to Allow for Optimised Integration of Textile Implants, Institute for Hygiene and Biotechnology (IHB)

Azo Nanotechnology -- Even modern implants made of resorbable biopolymers, such as polylactic acid, break down in the body after a certain period of time and decompose into individual acidic components. They can then cause considerable problems around the implantation site ranging from inflammations to rejection. That is why biotolerability is a decisive factor in the rapid generation of blood vessels at the implantation site (known as angiogenesis). New capillaries ensure that acidic decomposition products resulting from the breakdown of bioresorbable textile implants can be quickly transported away from the area. At the same time, the new blood supply guarantees that cells involved in building up tissue receive sufficient nutrients and the implant is integrated into the tissue rather than being encapsulated as a foreign body.
