Harnessing power of CRISPR to control behavior of DNA-responsive materials

The CRISPR-Cas system has become the go-to tool for researchers who study genes in an ever-growing list of organisms, and is being used to develop new gene therapies that potentially can correct a defect at a single nucleotide position of the vast reaches of the genome.

Scientists 3D print full-scale functioning heart components for the first time

Researchers have developed a new 3D bioprinting method that can produce any part of the heart, from tiny capillaries through to full-scale heart components.

New gel reduces post-surgery scar tissue in animals

Researchers at Stanford University have found that spraying a gel on the internal tissues of animals after cardiac surgery greatly reduces adhesions, fibrous bands that form between internal organs and tissues. Adhesions can cause serious, even fatal, complications.

Bioinspired adhesive dressings could accelerate wound healing

Cuts, scrapes, blisters, burns, splinters, and punctures - there are a number of ways our skin can be broken. Most treatments for skin wounds involve simply placing a barrier over them (usually an adhesive gauze bandage) to keep it moist, limit pain, and reduce exposure to infectious microbes, but do not actively assist in the healing process.

Single-cell encapsulation technology can protect transplanted MSCs from immune attack

Bone marrow transplants of hematopoietic stem cells have become standard treatment for a host of conditions including cancers of the blood and lymphatic systems, sickle cell anemia, inherited metabolic disorders, and radiation damage.

UGR scientists design new hydrogel that aids in cartilage regeneration

Cartilage degeneration and damage treatment remain a major challenge in today's society; hence, tissue engineering strategies are being developed to investigate new alternatives based on a combination of cell therapy and 3D scaffolds to support cartilage cells

Artificial DNA can help release active ingredients from drugs in sequence

A drug with three active ingredients that are released in sequence at specific times: Thanks to the work of a team at the Technical University of Munich, what was once a pharmacologist's dream is now much closer to reality.

Injectable hydrogel offers double punch against bone infections

Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved.

CityU scientist receives grant for new way to cultivate 10 distinct probiotic bacteria

An environmental scientist at City University of Hong Kong has been awarded US$100,000 by Grand Challenges Explorations, an initiative of the Bill & Melinda Gates Foundation, for a novel way to cultivate 10 distinct probiotic bacteria simultaneously.

Novel microfluidic device captures and isolates circulating tumor cell clusters

Cancer touches nearly everyone in one way or another, and regrettably, it will claim another 600,000 lives in the U.S. in 2019, according to the American Cancer Society. Researchers from San Diego State University, TumorGen MDx Inc., and Sanford Burnham Prebys Medical Discovery Institute set out to explore a seemingly basic question: What is it about cancer that kills?

New process enables 3D printing of biological tissues without scaffolds

Engineered tissues and organs have been grown with various degrees of success in labs for many years. Many of them have used a scaffolding approach where cells are seeded onto biodegradable supportive structures that provide the underlying architecture of the organ or tissue desired.

A 'homing beacon' for cancer drugs

Killing tumor cells while sparing their normal counterparts is a central challenge of cancer chemotherapy. If scientists could put a “homing beacon” in tumors, they could attract these medicines and reduce side effects caused by the drugs acting on healthy cells.
