Conductive hydrogel could replace brain tissue
Due to their tissue-like mechanical properties, hydrogels are being increasingly used for biomedical applications; a well-known example are soft contact lenses. These gel-like polymers consist of 90 percent water, are elastic and particularly biocompatible. Hydrogels that are also electrically conductive allow additional fields of application, for example in the transmission of electrical signals…

High energy radiotherapy ‘paints’ tumours, avoids healthy tissue
A radiotherapy technique which ‘paints’ tumours by targeting them precisely, and avoiding healthy tissue, has been devised in research led by the University of Strathclyde. Researchers used a magnetic lens to focus a Very High Electron Energy (VHEE) beam to a zone of a few millimetres. Concentrating the radiation into a small volume of high dose will enable it to be rapidly scanned across a…

Lab-grown ‘mini-bile ducts’ to repair human livers
Scientists have used a technique to grow bile duct organoids – often referred to as ‘mini-organs’ – in the lab and shown that these can be used to repair damaged human livers. This is the first time that the technique has been used on human organs. The research paves the way for cell therapies to treat liver disease – in other words, growing ‘mini-bile ducts’ in the lab as…

A 'FRESH' way to 3D-print tissues and organs
Research into 3D bioprinting has grown rapidly in recent years as scientists seek to re-create the structure and function of complex biological systems from human tissues to entire organs. The most popular 3D printing approach uses a solution of biological material or bioink that is loaded into a syringe pump extruder and deposited in a layer-by-layer fashion to build the 3D object. Gravity,…

New imaging method reveals bacteria hiding from antibiotics
Researchers at the Francis Crick Institute and the University of Western Australia have developed a new imaging method to see where antibiotics have reached bacteria within tissues. The method could be used to help develop more effective antibiotic treatments, reducing the risk of antibiotic resistance.

Regrow cartilage in joints? Science says you can
Contrary to popular belief, cartilage in human joints can repair itself through a process similar to that used by creatures such as salamanders and zebrafish to regenerate limbs, researchers at Duke Health found. This process could be harnessed as a treatment for osteoarthritis. Publishing in the journal Science Advances, the researchers identified a new mechanism for cartilage repair.

A 'swift' way to 3D-print organs
Twenty people die every day waiting for an organ transplant in the U.S., and while more than 30,000 patients now receive transplants annually, another 113,000 are currently on organ waitlists. Many people see artificially grown human organs as the Holy Grail for resolving the organ shortage, and advances in 3D printing have led to a boom in using that technique to build living tissue constructs…

Patching up a damaged heart
Scientists in the UK have developed tiny patches of engineered heart tissue that have the potential to be implanted to help people recover from a heart attack. Measuring approximately 3cm x 2cm, the patches contain up to 50 million human-induced pluripotent stem cell derived cardiomyocytes (hiPSC-CM). Yet, these are programmed to turn into working heart muscle that can beat and gradually be…

How clots become firm in the presence of blood flow
Blood clotting is one of the most critical, protective processes in human physiology. When something goes wrong with clotting, either because there is too much clotting, leading to a stroke, or not enough, leading to internal bleeding, the outcome can be catastrophic. Now, University at Buffalo researchers have established an in vitro model of this process that will help clinicians improve…
