Laser-activated silk sealants outperform sutures for tissue repair

Researchers have developed laser-activated nanomaterials that integrate with wounded tissues to form seals that are superior to sutures for containing body fluids and preventing bacterial infection. Tissue repair following injury or during surgery is conventionally performed with sutures and staples, which can cause tissue damage and complications, including infection. Glues and adhesives have…

Advancing technique for of personalied bone grafts

Scientists have developed a new bone engineering technique called Segmental Additive Tissue Engineering (SATE). The technique allows researchers to combine segments of bone engineered from stem cells to create large scale, personalized grafts that will enhance treatment for those suffering from bone disease or injury through regenerative medicine.

New staining method enables Nano-CT imaging of tissue samples

To date, examining patient tissue samples has meant cutting them into thin slices for histological analysis. This might now be set to change – thanks to a new staining method devised by an interdisciplinary team from the Technical University of Munich (TUM). This allows specialists to investigate three-dimensional tissue samples using the Nano-CT system also recently developed at TUM. Tissue…

Can mice really mirror humans when it comes to cancer?

A new Michigan State University study is helping to answer a pressing question among scientists of just how close mice are to people when it comes to researching cancer. The findings, now published in PLOS Genetics, reveal how mice can actually mimic human breast cancer tissue and its genes, even more so than previously thought, as well as other cancers including lung, oral and esophagus.…

Growing cells in three dimensions

Tissue engineering, broadly described as the combination of cells, engineering methods and biochemical factors to create living biological tissue, is a fast-growing field that has the potential to significantly accelerate the advancement of medicine. In IDTechEx’s new report, Tissue Engineering 2018 – 2028: Technologies, Markets, Forecasts, the market for engineered living tissues is…

Biology of Ageing

Road map to a longer life

In old age a variety of cellular processes decline and the risk to develop age-related diseases such as Alzheimer’s, Parkinson’s or Diabetes increases dramatically. But does ageing affect all organs and tissues in the body in the same way? And should drugs that are developed to improve health in old age have the same effect on every organ? Now scientists from the Max Planck Institute for…

Badly sunburned? Vitamin D can help

High doses of vitamin D taken one hour after sunburn significantly reduce skin redness, swelling, and inflammation, according to double-blinded, placebo-controlled clinical trial out of Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center.

Cancer development

Tumor induction from a distance

Current view is that cancer development is initiated from cells that acquire initial DNA mutations. These in turn provoke additional defects, and ultimately the affected cells begin to proliferate in an uncontrolled manner to develop primary tumors. These can later spread and create metastases, or secondary tumors, in other parts of the body. However, according to a study by researchers at the…

Handheld scanner reveals vascularization in psoriasis patients

A newly developed tissue scanner allows looking under the skin of psoriasis patients. This provides clinically relevant information, such as the structure of skin layers and blood vessels, without the need for contrast agents or radiation exposure. A team of researchers from Helmholtz Zentrum München and the Technical University of Munich (TUM) recently introduced the technology in ‘Nature…

3D bioprinting of cartilage could soon be a reality

A team of researchers at Sahlgrenska Academy has managed to generate cartilage tissue by printing stem cells using a 3D-bioprinter. The fact that the stem cells survived being printed in this manner is a success in itself. In addition, the research team was able to influence the cells to multiply and differentiate to form chondrocytes (cartilage cells) in the printed structure.

Scientists tissue-engineer part of human stomach

Researchers at Cincinnati Children’s Hospital Medical Center grew functional stomach and intestinal tissues to study diseases and new drugs. They use pluripotent stem cells to generate human stomach tissues in a petri dish that produce acid and digestive enzymes.

Lower limb trauma – reconstruction or amputation?

‘Amputation v. reconstruction’ – a vital issue – was debated by two leading surgeons during the Microsurgical Lower Limb Reconstruction session at the Advances and Controversies in Reconstructive Microsurgery (ACRM) 2016 conference, held in the United Kingdom this May. Consultant Plastic Surgeon Umraz Khan, from North Bristol NHS Trust presented a plastic surgeon’s view, while Ben…

MALDI Tissuetyper

The rapifleX is now available as TOF/TOF

The MALDI Tissuetyper is a system that records spatially resolved mass spectra directly from tissue. This allows the direct measurement of proteins, lipids and other molecular classes without the need for antibodies or molecular probes. This results in highly multiplexed datasets in which hundreds or thousands of compounds are measured simultaneously.

Living bone replicates original anatomical structure

A new technique developed by Gordana Vunjak-Novakovic, the Mikati Foundation Professor of Biomedical Engineering at Columbia Engineering and professor of medical sciences (in Medicine) at Columbia University, repairs large bone defects in the head and face by using lab-grown living bone, tailored to the patient and the defect being treated. This is the first time researchers have grown living…

Transmissibility of Alzheimer’s: No clinical symptoms

MedUni Vienna researchers have published the results of a clarifying research study on the potential transmissibility of Alzheimer’s disease. Although the protein associated with Alzheimer’s disease, amyloid-β, might be transmissible under very unusual circumstances, this does not go along with a transmission of the clinical manifestation of Alzheimer’s disease. The affected persons…

Imaging cells and tissues under the skin

Scientists have many tools at their disposal for looking at preserved tissue under a microscope in incredible detail, or peering into the living body at lower resolution. What they haven't had is a way to do both: create a three-dimensional real-time image of individual cells or even molecules in a living animal.
