Pluripotent stem cells generate lab grown human colons

Pluripotent stem cells generate lab grown human colons
Scientists used human pluripotent stem cells to generate human embryonic colons in a laboratory that function much like natural human tissues when transplanted into mice, according to research published in Cell Stem Cell. The study is believed to be the first time human colon organoids have been successfully tissue engineered in this manner, according to researchers at Cincinnati Children's Hospital Medical Center who led the project.

Can PCU improve valve function?

Can PCU improve valve function?
Pulsed cavitation ultrasound (PCU) can be used to remotely soften human degenerative calcified biosprosthetic valves and may significantly improve the valve opening function, according to a study published in JACC: Basic to Translational Science. Olivier Villemain, MD, et al., examined the effects of PCU on human bioprosthetic heart valves that were removed from patients because they were heavily calcified and were non-functional.

Project advances research on tissue bioregeneration

Project advances research on tissue bioregeneration
Traditionally, tissue regeneration research uses limited design criteria and a single goal approach. Despite regenerative medicine moving to the forefront of therapeutic strategies, the final product is frequently disappointing, meaning lengthy repetition of costly trials. The part EU-funded BIODESIGN (Rational bioactive materials design for tissue regeneration) project has completed an outcome-driven initiative with first class academic and industrial collaboration to change the tissue regeneration research arena.

Silk fibres help to mend broken bones

Silk fibres help to mend broken bones
Silk is an unlikely substitute for steel in any context, but for bone fractures, it may just be the perfect thing. A Swinburne researcher has developed a mix of cocoon silk fibres and biodegradable polymers that may one day hold bones together and help heal them from the inside out. Steel plates and bolts are often a surgeon's only tools for fixing fractured bones. The problem is that steel can block new bone cells from repairing the fracture. Removing the steel through further surgery can leave bones brittle.

Bioengineered human livers simulate natural development

Bioengineered human livers simulate natural development
An international team of researchers bioengineering human liver tissues uncovered previously unknown networks of genetic-molecular crosstalk that control the organ's developmental processes - greatly advancing efforts to generate healthy and usable human liver tissue from human pluripotent stem cells. The scientists report online in Nature that their bioengineered human liver tissues still need additional rounds of molecular fine tuning before they can be tested in clinical trials.

3D-printed patch guides growing blood vessels

3D-printed patch guides growing blood vessels
Ischemia results when narrowed, hardened or blocked blood vessels starve tissue, often resulting in heart attack, stroke, gangrene and other serious conditions. Surgery can correct the problem in large vessels, but treatment is much more complex in vessels that are smaller or damaged by prior treatment. Professor Christopher Chen, director of the Biological Design Center, is developing a method using 3D-printed patches infused with cells that offer a promising new approach to growing healthy blood vessels.

Heart tissue grown from stem cells improves drug testing

Heart tissue grown from stem cells improves drug testing
Researchers at the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR have engineered a three-dimensional heart tissue from human stem cells to test the safety and efficacy of new drugs on the heart. "Cardiotoxicity, which can lead to heart failure and even death, is a major cause of drug withdrawal from the market. Antibiotics, anticancer and antidiabetic medications can have unanticipated side effects for the heart".

Antimicrobial master batches aid medical device polymers

Antimicrobial master batches aid medical device polymers
Foster has introduced Combat antimicrobial master batches for blending with medical device polymers. Components made with these antimicrobial polymer blends kill harmful bacteria that leads to infections, including methicillin-resistant staphylococcus aureus (MRSA) and carbapenem-resistant enterobacteriaceae (CRE). According to a survey by the Center for Disease Control (CDC), 4% of inpatients in U.S. acute care hospitals contract at least one healthcare associated infection.

3D printed pediatric stents grow with patient’s vessels

3D printed pediatric stents grow with patient’s vessels
A study demonstrates proof-of-concept for combining computational design and simulation tools with 3D printing technology to produce self-expandable polymer stents that can grow with pediatric patients, are biodegradable, and require only a minimally-invasive procedure for implantation. This innovative method is described in an article in 3D Printing and Additive Manufacturing.

Muscle grafts help amputees sense and control artificial limbs

Muscle grafts help amputees sense and control artificial limbs
A surgical technique devised by MIT researchers could allow prosthetic limbs to feel much more like natural limbs. Through coordination of the patient’s prosthetic limb, existing nerves, and muscle grafts, amputees would be able to sense where their limbs are in space and to feel how much force is being applied to them. This type of system could help to reduce the rejection rate of prosthetic limbs, which is around 20%.
