In a major medical breakthrough, MBM researchers have “printed” the world’s first 3D vascularised engineered heart using a patient’s own cells and biological materials. Until now, scientists in regenerative medicine — a field positioned at the crossroads of biology and technology — have been successful in printing only simple tissues without blood vessels.

“This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” says Prof. Tal Dvir.

Heart disease is the leading cause of death among both men and women in the United States. Heart transplantation is currently the only treatment available to patients with end-stage heart failure. Given the dire shortage of heart donors, the need to develop new approaches to regenerate the diseased heart is urgent.

A new understanding of our relationship with our ‘friendly’ gut microbes shows they actually have a dark side and help cause ageing. Here’s how to fight back.

Every year, more than 5 million people in the USA are diagnosed with heart valve disease, but this condition has no effective long-term treatment. When a person’s heart valve is severely damaged by a birth defect, lifestyle, or aging, blood flow is disrupted. If left untreated, there can be fatal complications.

Valve replacement and repair are the only methods of managing severe valvular heart disease, but both often require repeated surgeries that are expensive, disruptive, and life-threatening. Most replacement valves are made of animal tissue and last up to 10 or 15 years before they must be replaced. For pediatric patients, solutions are extremely limited and can require multiple reinterventions.

Now, Georgia Tech researchers have created a 3D-printed heart valve made of bioresorbable materials and designed to fit an individual patient’s unique anatomy. Once implanted, the valves will be absorbed by the body and replaced by new tissue that will perform the function that the device once served.

Georgia Tech researchers have developed a groundbreaking 3D-printed, bioresorbable heart valve that promotes tissue regeneration, potentially eliminating the need for repeated surgeries and offering a transformative solution for both adult and pediatric heart patients.

Medical breakthroughs could mean that more of us will live to be 100 or even more, according to longevity medicine expert Dr. Edouard Debonneuil co-founder of the London-based Longevity Clinic who says that modern technology, new medicine, additional medical breakthroughs, and healthy living could help more of us reach that mammoth milestone.

“If the current trend continues, we could see individuals living to 140 or 150 in good health. While that might sound sensational, it’s grounded in science and the longevity field is booming because of these breakthroughs,” said Dr. Debonneuil after a first-of-its-kind study, Rejuvenation Olympics, which produced promising anti-aging results.

“One of the guys taking part is in his 60’s but biologically he resembles someone in their later 30’s. Some participants halved their biological age within two to three years and have reduced their ageing rate by 40 percent. This is a significant leap in human history, we now have the tools to age slowly,” continued Debonneuil.

Topical ABT-263 effectively reduced several senescence markers in aged skin, preparing it for improved wound healing. Researchers from Boston University’s School of Medicine have identified a promising treatment that could improve wound healing in aging skin. Their study, published in the journal Aging, reveals that the drug ABT-263 can significantly accelerate skin repair by eliminating old, damaged cells known as senescent cells.
