Fixing traumatic injuries to the skin and bones of the face and skull is difficult because of the many layers of different types of tissues involved, but now, researchers have repaired such defects in a rat model using bioprinting during surgery, and their work may lead to faster and better methods of healing skin and bones.
“This work is clinically significant,” said Ibrahim T. Ozbolat, Hartz Family Career Development Associate Professor of Engineering Science and Mechanics, Biomedical Engineering and Neurosurgery, Penn State. “Dealing with composite defects, fixing hard and soft tissues at once, is difficult. And for the craniofacial area, the results have to be esthetically pleasing.”
Currently, fixing a hole in the skull involving both bone and soft tissue requires using bone from another part of the patient’s body or a cadaver. The bone must be covered by soft tissue with blood flow, also harvested from somewhere else, or the bone will die. Then surgeons need to repair the soft tissue and skin.
As of 2015940 million people suffer from a form of visual impairment. Today, some forms of blindness can be cured by cornea implants and other procedures. Other forms of blindness like glaucoma (where the issue is related to the optic nerve) are beyond our abilities to fix. Despite advances in bioprinting and camera miniaturization, the issue of optical connection remains when attempting to replace the human eye. So far, technological progress has largely not risen to the challenge that 2.0 poises.
Three-dimensional “bio-printing” and real cow cells — an achievement that’s prompting the Israeli startup to eye other meat…The firm’s technology prints living cells that are incubated to grow, differentiate and interact to acquire the texture and qualities of a real steak. “It incorporates muscle and fat similar to its slaughtered counterpart,” Aleph Farms said, adding that the product boasts the same attributes “of a delicious tender, juicy ribeye steak you’d buy from the butcher.”
Scientists from UNSW Sydney have developed a ceramic-based ink that may allow surgeons in the future to 3D-print bone parts complete with living cells that could be used to repair damaged bone tissue.
Using a 3D-printer that deploys a special ink made up of calcium phosphate, the scientists developed a new technique, known as ceramic omnidirectional bioprinting in cell-suspensions (COBICS), enabling them to print bone-like structures that harden in a matter of minutes when placed in water.
While the idea of 3D-printing bone-mimicking structures is not new, this is the first time such material can be created at room temperature—complete with living cells—and without harsh chemicals or radiation, says Dr. Iman Roohani from UNSW’s School of Chemistry.
Researchers at EPFL have developed an approach to print tiny tissues that look and function almost like their full-sized counterpart. Measuring just a few centimeters across, the mini-tissues could allow scientists to study biological processes—and even test new treatment approaches—in ways that were previously not possible.
For years, mini versions of organs such as the brain, kidney and lung—known as “organoids”—have been grown from stem cells. Organoids promise to cut down on the need for animal testing and offer better models to study how human organs form and how that process goes awry in disease. However, conventional approaches to grow organoids result in stem cells assembling into micro-to millimeter-sized, hollow spheres. “That is non-physiological, because many organs, such as the intestine or the airway, are tube-shaped and much larger,” says Matthias Lütolf, a professor at EPFL’s Institute of Bioengineering, who led the study published today in Nature Materials.
To develop larger organoids that resemble their normal counterparts, Lütolf and his team turned to bioprinting. Just as 3D-printers allow people to create everyday objects, similar technology can help bioengineers to assemble living tissues. But instead of the plastics or powders used in conventional 3D-printers, bioprinters use bioinks—liquids or gels that encapsulate living cells. “Bioprinting is very compelling because it allows you to deposit cells anywhere in 3D space, so you could think of arranging cells into an organ-like configuration such as a tube,” Lütolf says.

This may be good news for those who have damaged joints due to sports or old age.
Human knees are notoriously vulnerable to injury or wearing out with age, often culminating in the need for surgery. Now researchers have created new hybrid bioinks that can be used to 3D print structures to replace damaged cartilage in the knee.
The meniscus is the rubbery cartilage that forms a C-shaped cushion in your knee, preventing the bones of your upper and lower leg from rubbing against each other. This stuff is susceptible to damage from sports injuries, but can also wear out with age – and if it gets particularly bad, sometimes the only thing left to do is surgically remove some of the damaged meniscus.
For the new proof-of-concept study, researchers at the Wake Forest Institute for Regenerative Medicine (WFIRM) demonstrated a new method for 3D bioprinting that creates both the cartilage and the supporting structures. The team used the Integrated Tissue and Organ Printing System (ITOPS), which has been used in past studies to print complex tissues such as bones, muscles and even ears.
Recreating human body parts using a 3D printer. This is possible in the Netherlands with the new bioprinter developed by Utrecht University and UMC Utrecht. This printer can be used to make models of organs or bones, amongst other things. These printed models can be made up of living cells on which medication can be tested, for instance.
Conventional 3D printers work by stacking plastic layers on top of each other. This build-up of layers creates a three-dimensional figure. There are already countless possibilities with these standard 3D printers. Science has been looking for years at how this technique can be applied across different areas.
Printing living cells
Scientists have already tried to print prostheses or entire organs before. So far, they have never really succeeded. However, there are some 3D printers that are able to cope with sensitive materials that contain living cells.
