Researchers successful in healing deep wounds using 3D bioprinted skin

Posted by in categories: 3D printing, bioprinting, biotech/medical

Researchers from the University of Birmingham and the University of Huddersfield, UK, have developed a new 3D bioprinting technique that can be used to treat chronic wounds.

Named Suspended Layer Additive Manufacturing (SLAM), the approach enables the printing of a novel biomaterial that accurately simulates the structure of mammalian skin.

In fact, according to the researchers, the biomaterial is the first of its kind to simulate all three of the major layers found in skin – the hypodermis, the dermis, and the epidermis – making it a unique tri-layered skin equivalent. Early experiments suggest that the 3D bioprinted skin can be placed at the site of a wound to induce healing, reducing scar tissue in the process.

Astronauts test 3D bioprinted skin bandages in space

Posted by in categories: bioprinting, biotech/medical, space travel

About the Bioprint FirstAid Handheld Bioprinter capabilities.

Astronauts on the International Space Station (ISS) are testing 3D bioprinted bandages made of their own cells that could be used to better heal flesh wounds in space.

The German Space Agency (DLR) is leading the experiment which was launched to the ISS at the end of December 2021 on SpaceX’s 24th commercial resupply mission. The payload contained the BioPrint FirstAid Handheld Bioprinter, which is designed to hold cells from astronauts within a bioink that can be used to apply bandages to wounds when needed.

3D-bioprinted tissues can now be stored in the freezer until needed

Posted by in categories: 3D printing, bioprinting, biotech/medical

A major obstacle to widespread study and clinical use of 3D tissues is their short shelf-life, which may be anywhere from a just few hours to a few days. As in the case of an organ transplant, a bioprinted tissue must be transported rapidly to the location where it is needed, or it will not be viable. In the journal Matter on December 21st, researchers at Brigham and Women’s Hospital and Harvard Medical School describe their work combining 3D bioprinting with cryopreservative techniques to create tissues which can be preserved in a freezer at-196°C and thawed within minutes for immediate use.

“For conventional bioprinting, there is basically no shelf life. It’s really just print, and then use, in most cases,” says lead author Y. Shrike Zhang (@shrikezhang), a biomedical engineer at Brigham and Women’s Hospital. “With cryobioprinting, you can print and store in the frozen state for basically as long as you want.”

Posted by in categories: bioprinting, science, space travel

The 24thSpaceX cargo resupply services mission, targeted to launch in late December from NASA’s Kennedy Space Center in Florida, carries scientific research and technology demonstrations to the International Space Station. The experiments aboard include studies of bioprinting, crystallization of monoclonal antibodies, changes in immune function, plant gene expression changes, laundering clothes in space, processing alloys, and student citizen science projects.

Texas researchers develop new bioink specifically for 3D bioprinting blood vessels

Posted by in categories: 3D printing, bioprinting, biotech/medical, engineering

A team of researchers from Texas A&M University’s Department of Biomedical Engineering has designed and 3D bioprinted a highly realistic model of a blood vessel.

The model is made of a newly nanoengineered, purpose-built hydrogel bioink and closely mimics the natural vascular function of a real blood vessel, as well as its disease response. The team hopes its work can pave the way for advanced cardiovascular drug development, expediting treatment approval while eliminating the need for animal and human testing altogether.

“A remarkably unique characteristic of this nanoengineered bioink is that regardless of cell density, it demonstrates a high printability and ability to protect encapsulated cells against high shear forces in the bioprinting process,” said Akhilesh Gaharwar, associate professor at the university and co-author of the study. “Remarkably, 3D bioprinted cells maintain a healthy phenotype and remain viable for nearly one month post-fabrication.”

Japanese scientists produce first 3D-bioprinted, marbled Wagyu beef

Posted by in categories: bioprinting, biotech/medical, food

The world of lab-grown meats is fast filling with all kinds of tasty bites, from burgers, to chicken breasts, to a series of increasingly complex cuts of steak. Expanding the scope of cultured beef are scientists from Japan’s Osaka University, who have leveraged cutting-edge bioprinting techniques to produce the first lab-grown “beef” that resembles the marbled texture of the country’s famed Wagyu cows.

From humble beginnings that resembled soggy pork back in 2,009 to the classic steaks and rib-eyes we’ve seen pop up in the last few years, lab-grown meat has come along in leaps and bounds. The most sophisticated examples use bioprinting to “print” living cells, which are nurtured to grow and differentiate into different cell types, ultimately building up into the tissues of the desired animal.

The Osaka University team used two types of stem cells harvested from Wagyu cows as their starting point, bovine satellite cells and adipose-derived stem cells. These cells were incubated and coaxed into becoming the different cell types needed to form individual fibers for muscle, fat and blood vessels. These were then arranged into a 3D stack to resemble the high intramuscular fat content of Wagyu, better known as marbling, or sashi in Japan.

Rapid new bioprinting method unlocks potential of human tissue transplants

Posted by in categories: 3D printing, bioprinting, biotech/medical

Scientists from the University at Buffalo have developed a rapid new 3D bioprinting method that could represent a significant step towards fully-printed human organs.

Using a novel vat-SLA-based approach, the team have been able to reduce the time it takes to create cell-laden hydrogel structures, from over 6 hours to just 19 minutes. The expedited biofabrication method also enables the production of embedded blood vessel networks, potentially making it a significant step towards the lifesaving 3D printed organs needed by those on transplant waiting lists.

“Our method allows for the rapid printing of centimeter-sized hydrogel models,” explained the study’s lead co-author, Chi Zhou. “It significantly reduces part deformation and cellular injuries caused by the prolonged exposure to the environmental stresses you commonly see in conventional 3D printing.”
