Lab-grown living bone fuses fast with pig jaw

Repairing damaged or defective bone structures can be quite difficult, painful, and expensive for patients requiring the care. While advances have been made in replacing sections of bone and stimulating natural healing, researchers from Columbia University have developed a bone-growing technique that precisely replicates original structures in the head and face.Read More

Active and passive in-cell movements distinguished for the first time

If you looked inside any cell in your body right now, you'd notice that the individual structures and components within it are constantly moving around. While some of that twitching and jostling is passive, other movement is more deliberate, with the cell actively exerting energy to move components. A new data analysis technique is improving our ability to distinguish between those two types of movement, and the results could significantly improve our understanding of cell biology.Read More

Creation of insulin-releasing cells in a dish offers hope of diabetes therapy

A molecular switch could hold the key to a personalized cell replacement therapy for diabetes. Both Type 1 and Type 2 diabetes are characterized by an inability to produce (or process) insulin, which is required to regulate blood sugar levels. This has been linked to malfunctioning or failing beta cells in the pancreas, but so far scientists have struggled to produce effective replacement cells in the lab. Now a team at Salk Institute believes the problem has been solved.Read More

Humans could get salamander-like tissue regeneration abilities in "a few years"

In what could prove to be a game changer in stem cell therapy, a team led by scientists at the University of New South Wales (UNSW) have discovered a way to reprogram bone and fat cells to become stem cells that can regenerate multiple tissue types. The technique has already proved successful in mice and could be just a few years away from being safely available for regenerating any damaged tissue in humans.Read More

Time-lapse captures the death of white blood cells for the first time

With a pivotal role in fending off infections and disease, white blood cells are the engine room of the body's immune system. But little was known about what happens exactly when these cells reach the end of their life cycles. Scientists have now captured the death of white blood cells on camera for the first time, showing that they eject much of their contents while decomposing. One reason for this could be to warn neighboring cells of dangerous pathogens in the area. The researchers say learning more about their expiration could help bring about improved health treatments in the future. Read More

Researchers identify how cells get their orders to heal wounds

When you cut on your finger or scrape your knee, cells rush to the wound and repair or replace the damaged tissue. But how exactly this works – in particular how certain cells become "leaders" in the process – has long been a mystery. Now researchers at the University of Arizona (UA) have identified the mechanisms that cause and regulate this collective cell migration. Armed with this knowledge, biomedical engineers will be able to design new tissue regeneration treatments for diabetes and heart disease as well as for slowing or stopping the spread of cancer.Read More

3D Cell Explorer produces 3D holograms of living cells in near real time

Swiss company Nanolive has created 3D Cell Explorer, a new technology that creates vibrantly detailed 3D holograms of living cells on the nanometric scale. Created through combining 3D imagery with digital staining, the new microscope offers researchers and hospitals a novel tool to non-invasively peer inside living cells almost in real time, opening up new areas of biological research.Read More

Researchers shed new light on skin-based immune system

The skin is the body's first line of defense against infection, with an extensive network of skin-based immune cells responsible for detecting the presence of foreign invaders. However, in addition to pathogens, an immune response can be triggered by allergens or even our own cells, resulting in unwanted inflammation and allergies. Researchers have now shed new light on the way the immune system in our skin works, paving the way for future improvements in tackling infections, allergies and autoimmune diseases.Read More
