   Shaochen Chen, a Professor in the Nanoengineering Department at the University of California, led a team of nano-engineers in creating a new method for “3D printing biomimetic blood vessel networks, which may help lay the foundation for functioning lab-grown tissue and organs.”

    According to Digital Trends, “Artificial blood vessel networks — which help transport nutrients, blood, and waste — have been 3D printed by other researcher labs in the past, though these methods have proven to be time-consuming and expensive. In his research, Chen sought to make the process faster and cheaper and to develop a network sophisticated enough to be integrated with the human body.”

    Chen and his team used “hydrogel biomaterials that are biocompatible for potential clinical uses.”

    They also  “used multiple cell types and a new 3D-printing method they developed themselves” to make the artificial vessels more efficient.

    “While traditional techniques may take hours to complete, the UC San Diego lab can complete the task in just a few seconds, according to the researchers, who published a paper detailing their study in the journal Biomaterials.”

    Using mice for testing, the researchers have so far been able to “graft the 3D-printed tissue into the skin wounds of mice. After two weeks, they analyzed the wounds again and saw that the lab-grown tissue had successfully integrated into the host’s blood vessel network.”

    This is very good news, as we are coming very close to being able to make artificial tissue and organs, which would be able to help a lot of people in the future.
