Korean researchers have been experimenting further in the bioprinting of tracheal implants, publishing recent results in ‘Trachea with Autologous Epithelial Cells and Chondrocytes.’ The team of scientists details their use of polycaprolactone and hydrogel mixed with nasal epithelial and auricular cartilage cells.

After bioprinting an artificial trachea with these materials and tissue, they transplanted them into 15 rabbits, six of which were a control group. The goal was to find a way to overcome tracheal problems due to tumors, the most common of which are adenoid cystic carcinomas and squamous cell carcinomas. Previously there have been substantial challenges in creating viable tracheas that are anatomically correct and can produce a ciliated epithelium. Issues have arisen with infection, implants that become dislodged, have migrated, or experienced obstruction.

A new study shows that 3D-printing a section of spinal cord, living cells and all, restored movement in injured rats.

United Therapeutics will license, develop, and commercialize CollPlant Holdings’ recombinant human collagen (rhCollagen) and BioInk technology for 3D bioprinting of solid-organ scaffolds for human transplants, the companies said today, through a collaboration that could generate more than $44 million.

Through its wholly- owned organ manufacturing and transplantation-focused subsidiary Lung Biotechnology PBC, United Therapeutics has been granted what the companies termed an exclusive license “throughout the universe” by CollPlant to its technology for producing and using rhCollagen-based BioInk for 3D bioprinted lung transplants.

Lung Biotechnology PBC is a public benefit corporation formed to address the acute national shortage of transplantable lungs and other organs with a variety of technologies that either delay the need for such organs or expand the supply.

Medical research has taken a leap into the future as Russian scientists have managed to grow a mouse’s thyroid in zero gravity using a 3D bioprinter on the International Space Station (ISS). And human organs may be next in line.

The breakthrough device dubbed Organaut was delivered to the ISS by a Soyuz MS-11 spacecraft on December 3 by Expedition 58.

3D bioprinting continues to diversify as more and more companies and research organizations join the field, each bringing their own take on the technology to the table. French collaborative platform 3D.fab has an intriguing approach towards bioprinting that involves a freeform robot capable of directly printing on a part of the body. In the video below, the BioAssemblyBot prints what appears to be a bandage directly on an arm:

After successfully transplanting the first 3D-printed cornea in an animal, North Carolina company Precise Bio has recently announced the launch of a dedicated business for creating marketable, 3D-printed products for human eyes. Founded by scientists from the Wake Forest Institute of Regenerative Medicine, this company is developing bio-fabrication printers that can restore cells, tissues, and organs. Their proprietary technology, a 4D bio-printing platform, is said to resolve existing limitations presented by other bioprinters to enable more complex tissues to be engineered for transplants and treatments. By focusing on developing marketable products for the eye, the company aims to achieve rapid advancement in its field and move to overhaul the whole organ transplant system.

When a cornea is damaged by disease or injury, a replacement is often needed to restore vision. Transplant surgery using donated corneas is an available solution, however, it relies on a deceased donor. While the waiting list in the United States is nearly non-existent, other countries require longer wait times, some over a year, before one is available. The Eye Bank Association of America estimates that around 10 million people suffer from corneal blindness that could potentially be restored via transplant surgery. An artificially manufactured cornea would overcome supply limitations while also contributing to the knowledge base to develop more complex organs such as hearts and livers.

Stem cell research firm Celprogen Inc. has been working on something quite exciting for some time now, which has remained largely under the radar until very recently. The California-based company announced it has successfully 3D printed a human brain organelle using brain stem cells. The bioprinted brain could have applications in studying neurological diseases.

More than just announcing the bioprinted brain organelle, Celprogen has also used the brain to study the “role of Microglia activation and deactivation in neurological diseases.” Through this research and experimentation, the company says it has identified and characterized 11 lead compounds that could be potential drug candidates for diseases such as Alzheimer’s, Parkinson’s and Glioblastoma.
