UCB Researchers Help Bioprinting Tissue Become Safer and More Affordable

  • Bioprinting with tissues… It is a thing that just a few years ago may be an outrageous thought, but now, it’s becoming additional and additional of a reality. Last year, one Wake Forest professor, Dr. James Yoo, said with confidence that these bioprinted tissues can be implanted into human patients inside a 10 year timeframe. Now, researchers of the University of British Columbia have just revealed the development of a new chemical compound that stands to manufacture bioprinting tissues safer and additional inexpensive

    The chemical compound is a new type of biological ink utilized in the 3D printing of tissue, that is able-bodied to function without the use of UV light processs, via a much safer and additional conventional light source instead. In fact, the bioink may turn it into biological tissue via an day to day light projector.

    “UV light is known to be cancer-cavia and can injure a cell’s DNA, that is not thoughtl when attempting to turn it into tissue for medical purposes,said Keekyong Kim, the head researcher and assistant professor of Engineering at UBC. “By developing our own bio-ink, we can turn it into bone, cartilage and tissue without the risk that we can manufacture the cells sick in the development process.”

    The 3D printing process works by combining processed cells with the newly created bioink, that turn it intos a hydrogel when exposed to light. Kim and his team utilized SLA printing in order to create the biomaterial in a layer by layer style, creating a scaffolding process to allow bone and tissue regeneration. For Kim, the largest factor of the research was photo-initiating chemical compound that allowed the bioink to react to the much safer and inexpensive
    light projector, much like to the light source utilized for 3D printing with plastics.

    “With our photo-initiator, we were able-bodied to use a additional conventional light source, that hadn’t quite been tried in 3D bio-printing before,”said Kim.“The outcome is we are able-bodied to manufacture medical tissue in a way that is not just safer, it’s cheaper.”

    Recently published in the Biofabrication journal, Kim and his collaborators, that comes with Zongjie Wang, Raafa Abdulla, Benjamin Parker, Roya Samanipour and Sanjoy Ghosh, stand to hustle bioprinting towards actual implantation in the near next. Perhaps they can beat out Dr. Yoo’s 10-year projection, delivering bioprinted tissues and bones to the human body faster than we may have at any time imagined.
