Collagen is a fibrous protein found in cartilage and other connective tissue.
Collagen, the main component of the skin's extracellular matrix, can cause a pathological condition if it is in excess. Applying an electric field to the skin affects collagen pathways, temporarily reducing collagen production and increasing its degradation.
Although sometimes hard to accept, with aging, many things in our bodies change. One of these is the ability of the skin to regenerate. Old skin is just not as good as young skin at healing wounds. However, the molecular and cellular mechanisms underlying this are largely unknown.
Most of the cells in our bodies – be they bone, muscle or pancreas cells – are locked into the right place with the help of tiny anchors (called 'focal adhesions').
MIT engineers, in collaboration with scientists at Cancer Research UK Manchester Institute, have developed a new way to grow tiny replicas of the pancreas, using either healthy or cancerous pancreatic cells.
A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells.
Chronic alcohol abuse and hepatitis can injure the liver and lead to fibrosis, the buildup of collagen and scar tissue. As a potential approach to treating liver fibrosis, University of California San Diego School of Medicine researchers and their collaborators are looking for ways to stop liver cells from producing collagen.
A new automated process prints a peptide-based hydrogel scaffold containing uniformly distributed cells. The scaffolds hold their shapes well and successfully facilitate cell growth that lasts for weeks.
TARM1 is a receptor protein, whose function in the working of the immune system is not known yet. Now, in a new research work, Japanese researchers have analyzed mouse models to investigate the promising role of TARM1 protein in the pathogenesis of rheumatoid arthritis.
Astronauts face many challenges to their health, due to the exceptional conditions of spaceflight. Among these are a variety of infectious microbes that can attack their suppressed immune systems.
Imagine using stem cells from your bone marrow to grow a piece of bone tissue in the lab, after which medical doctors explore which drugs have the desired effect on your bones.
The lung is a complex organ whose main function is to exchange gases. It is the largest organ in the human body and plays a key role in the oxygenation of all the organs.
Breast cancer could be identified more precisely than existing methods using blood specimens and exclusive proteomics-based technology.
A multidisciplinary team of researchers at the University of Massachusetts Amherst's Institute for Applied Life Sciences (IALS) have developed a technique to replicate bone tissue complexity and bone remodeling processes.
Hitting a pothole on the road in just the wrong way might create a bulge on the tire, a weakened spot that will almost certainly lead to an eventual flat tire. But what if that tire could immediately begin reknitting its rubber, reinforcing the bulge and preventing it from bursting?
Fibrous proteins such as collagen and fibrinogen form a thin solid layer on the surface of an aqueous solution similar to the "skin" that forms on warm milk, according to a team of Penn State Researchers, who believe this finding could lead to more efficient bioprinting and tissue engineering.
Similar to other orange fruits and vegetables, mangoes have abundant beta-carotene and also contain antioxidants that may delay damage to cells.
Ligament injuries that affect scores of regular citizens and athletes are sidelined every year. Added to this, recovery is painful and takes a long time and, at times, a return to normal function is never achieved because of the formation of scars—an aspect that makes ligament injuries inclined to more damage.
The shells of crustaceans and wood waste such as branches pruned from trees usually end up in landfills. These waste materials are given a new lease of life to become nutritional supplements and medicine, with the help of a novel process developed by researchers from the National University of Singapore (NUS).
Human cells are encased by a membrane coated with diverse sugar molecules known as glycans. These glycans play many roles in health and disease, making them important to understand.
A global study has discovered the heart cells responsible for repairing the damage induced to this vital organ following infarction.
