In certain forms of cancer, connective tissue forms around and within the tumor. One previously unproven theory is that there are several different types of connective tissue cells with different functions, which affect the development of the tumor in different ways. Now, a research team at Lund University in Sweden has identified three different types […]

Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology – OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are the first researchers worldwide to combine magnetic resonance imaging (MRI) with a proton beam, thus demonstrating that in principle, this commonly used imaging method can indeed work with particle beam cancer treatments. This opens […]

Kidney infection with the fungal pathogen Candida albicans causes tissue damage. In wild-type mice, DNGR-1 expressed on dendritic cells detects this injury, and this triggers a reduction in the production of Mip-2, a chemokine that attracts neutrophils. Mice lacking DNGR-1 do not recognize the tissue injury and therefore do not reduce Mip-2 production. The resulting […]

In a new study, Tel Aviv University researchers reveal how they invented the first fully personalized tissue implant, engineered from a patient’s own materials and cells. The new technology makes it possible to engineer any kind of tissue implant from one small fatty tissue biopsy. “We were able to create a personalized hydrogel from the […]

A University of Arizona College of Medicine – Phoenix researcher has received a $393,493 grant from the National Institutes of Health to further her research in reducing the risk of heart failure in patients with high blood pressure. Taben Hale, PhD, a specialist in cardiovascular pharmacology and associate professor in the Department of Basic Medical […]

Oct 30 2018 A new gold standard for electrical measurement in the emerging in vitro world of three dimensional models. That’s what Swiss medtech 3Brain has established by partnering with CSEM. Its Khíron chip enables fast, accurate intra-tissue measurement and continuous nutrient and oxygen supply through all tissue layers for the first time. And it […]

There is a shortage of donor tissue for grafting procedures to replace damaged human tissue. Tissue engineering holds great promise for generating tissue, but clinical success has been limited because the resulting tissue fails to integrate in the patient’s body after transplantation. Tissue is complex, with multiple support structures, such as vascular and neural networks, […]

When someone has a deadly disease or sustains a life-threatening injury, a transplant or graft of new tissue may be the best — or only — treatment option. Transplanted organs, skin grafts and other parts need blood vessels to bring oxygen-rich blood their way, but for tissue engineers and regenerative medicine experts, making a functional […]

EPFL researchers have developed a hydrogel – made up of nearly 90% water – that naturally adheres to soft tissue like cartilage and the meniscus. If the hydrogel carries repair cells, it could help damaged tissue to heal. Some types of body tissue, like cartilage and meniscus, have little or no blood supply and are […]

Nov 16 2018 In optogenetics, researchers use light to control protein activity. This technique allows them to alter the shape of embryonic tissue and to inhibit the development of abnormalities. Now, scientists in EMBL’s De Renzis group have enhanced the technique to stop organ-shaping processes in fruit fly embryos. Their results, published in The EMBO […]

Today, the U.S. Food and Drug Administration permitted marketing of two devices that provide real-time location of parathyroid tissue during surgical procedures such as thyroidectomy (surgery to remove all or part of the thyroid) and parathyroidectomy (surgery to remove one or more parathyroid glands). “For some patients with parathyroid disease, treatment may mean a surgical […]

Advances in real-time hyperspectral imaging gives neurosurgeons new precision when operating on the brain, improving patient outcomes Identifying healthy from diseased tissue poses a unique problem for cancer surgeons. Even the smallest bits of a tumor left behind during surgery can regrow and spread to other organs, a deadly phenomenon called metastasizing. To guard against […]

Nanosystems that deliver anticancer drugs or imaging materials to tumors are showing significant progress, particularly those that respond to tumor-related stimuli, according to a review published in the journal Science and Technology of Advanced Materials. However, further research is still required to make sure these delivery systems are stable, non-toxic and biodegradable. Nanocarriers designed to […]
