A new step in 3D bioprinting technology

In the latest successes, the the scientist China and partners from British and Dutch universities have worked together to print a heart tissue that can survive in vitro and maintain a pulse for more than six months.

According to the results of the above study, published in the journal Bioactive Materials, researchers from the Chinese Academy of Sciences, Tsinghua University (China), the University of Manchester (UK) and Delft University of Technology (UK). Netherlands) has overcome the limitations of the systems bio printing conventionally by converting a 6-degree-of-freedom industrial robotic arm into a bioprinter, thereby allowing the printing of cells on complex circuit rigs 3D from all directions.

The research report states that several layers of cells are printed and co-cultured for a period of time to form a fusion of functional intercellular spaces and new capillaries between the printed cells. After that, a new batch of cells will continue to be printed. This process can form a network of blood vessels similar to internal organs and supports the long-term survival of printed tissues and organs.

In addition, the scientists also developed a method of printing cells based on bath oils to better preserve the natural functions of cells after printing. Together with a self-designed bioreactor and an iterative printing-culture method, the bioprinting system has the potential to create vascular, contractile, and long-lived cardiac tissues.

The scientists claim that this bioprinting method simulates the process of growing organs in a living organism, and offers a promising solution for the fabrication of complex organs in vitro.
