The epidermis is the thin, outer layer of the skin that is visible to the eye and works to provide protection to the body. It does not contain any blood vessels and is, therefore, dependent on the dermis, the layer of the skin underneath it, to provide access to nutrients and dispose of waste.
Scientists have, for the first time, demonstrated the presence of hemoglobin—a protein primarily known for its role in binding with oxygen within red blood cells—in the epidermis, the outermost tissue layer of human skin.
A research team, affiliated with UNIST has achieved a groundbreaking milestone in tissue regeneration by developing a technology that utilizes autologous blood to produce three-dimensional microvascular implants.
A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 12, entitled, "A novel peptide 'T14' reflects age and photo-aging in human skin."
An obscure aquatic plant has helped to explain how plants avoid cracking up under the stresses and strains of growth.
In a new study published in Nature Chemical Biology, an international team of researchers from the University of Georgia, USA, and the Max Planck Institute for Chemical Ecology in Jena, Germany, presents a promising strategy for elucidating metabolic pathways for plant compounds of medicinal importance.
Tropical oceans are typically nutrient-poor, yet they host vast biologically diverse reef ecosystems built by symbiotic cnidarians (including corals and anemones).
A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 8, entitled, "A chronic wound model to investigate skin cellular senescence."
In spite of the ongoing development of new targeted therapies, chemotherapies remain the most popular used treatment for patients with advanced cancers. Chemotherapy resistance is one of the leading causes of cancer treatment failure and death.
In the fruit fly Drosophila, a team led by Maria Leptin discovered that autophagy, a stress response process in cells, plays a significant role in wound repair.
During the Ice Age, giant mammals such as mammoths, sabre-toothed cats and woolly rhinoceroses once roamed Northern Europe and America.
QUT PhD researcher Lauren Ashwood has studied sea anemones' venom makeup extensively, in particular, Telmatactis stephensoni a reef-based sea anemone that can grow from 8 to 10 cm.
A study published today in Cell Reports reveals important insights into the molecular mechanisms that underpin the body's natural defenses against the development of skin cancer.
Chronic wounds are deep and difficult to repair. Often, the top of the injury heals before the bottom, so the wound collapses in on itself. Over time, this can result in scar tissue and reduced skin function.
Scientists headed a new study that determined the molecular mechanisms inside protein complexes that support cell-to-cell adhesion and communication.
Researchers have discovered that two plant stem cell proteins physically interact and regulate each other to prevent cellular division.
The human skin is essentially an organ, a fact that that is easy to forget. It is also the largest organ and is continuously exposed, charged with keeping the human inner biology safe from the threats of the outside world.
As the human body's largest organ, the skin is responsible for protecting against a wide range of possible infections on all fleshy surfaces, from head to toe. So how exactly does the skin organize its defenses against such an array of threats?
The skin is known to be the largest organ in the human body, and its outermost layer, called the epidermis, is renewed every three weeks.
Tohoku University scientists have, for the first time, provided experimental evidence that cell stickiness helps them stay sorted within correct compartments during development.
Scientists have successfully utilized a novel stem cell technology to examine the skin, specific to a group of living patients, in laboratory settings.
