The use of 3D printing-like techniques to combine cells, growth factors that mimic natural tissue characteristics is called bioprinting.

A team of scientists has drawn up a roadmap to drive research on site. The study was published in the journal Biofabrication. Leading researchers define the status, challenges and opportunities in this area and forecast the advances in science and technology needed to meet the challenges for a range of bioprint techniques and applications.

The guest editor Professor Wei Sun from Drexel University, Philadelphia, USA, and Tsinghua University, Beijing, China, presented the collection: "Cells are building blocks of nature. Bioprinting uses cells, proteins and biomaterials as building blocks for 3D printing of biological materials models, biological systems and therapeutic products. "It has quickly become the printing of biomaterials for tissue scaffolds and implants, the printing of cells or organoids for biological 3D models and the printing of microorganism chips for microphysiological Platforms and constructed living systems such as cell processing and bio robots.

"There are a number of challenges to be overcome, including the need for a new generation of novel organic beverages with multifunctional properties to better transport, protect and grow cells during and after printing; better printing processes and printers to handle cells with high levels To deliver survivability and. " High-precision, efficient and effective networking techniques and cross-linkers to maintain structural integrity and stability after printing, integration with microfluidic devices to provide printed models with a long-term and simulated physiological environment.

"Due to the rapid advances in bioprinting techniques and their widespread uses, the direction the area should develop is still evolving. The roadmap aims to address these unmet needs through a comprehensive summary and recommendations that are useful for experienced researchers and newcomers are useful in the field alike. "
