Epidermis

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.

Applying "temporal pressure" to the skin can help deliver more drugs

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and the Agency for Science, Technology and Research (A*STAR) have showed that applying "temporal pressure" to the skin of mice can create a new way to deliver drugs.

Study reveals mechanisms of mechanical stretch induced skin expansion

The capacity of the skin to expand by mechanical stretching has been used for decades in plastic and reconstructive surgery to generate an excess of skin that can be used to repair birth defects, damaged tissues, and breast reconstruction after mastectomy.

Researchers discover key signaling pathway in the pathogenesis of Paget's disease

Researchers from the University of California, Irvine, in collaboration with their colleagues from Beijing, China, have gained new insights into the development of poorly understood malignant skin cancers collectively known as Paget's disease.

Researchers discover mechanical cause for cell extrusion

The outer or inner boundaries of organs in the human body are lined with so-called epithelial sheets. These are layers of epithelial cells that can individually change their 3D shape -- which is what happens during biological processes like organ development (morphogenesis), physiological equilibrium (homeostatis) or cancer formation (carcinogenesis).

Creating hair-bearing human skin becomes a reality

For more than 40 years, scientists and commercial companies have been recreating human skin in laboratories around the world. Yet all of these products lack important aspects of normal skin--hair, nerves, and fat.

Hairy human skin grown from pluripotent stem cells

Building on years of groundbreaking discoveries in stem cell research, scientists from Indiana University School of Medicine and Harvard Medical School have determined how to grow hairy skin using human stem cells--developing one of the most complex skin models in the world.

Study reveals major changes that occur in mammalian skin cells during wound healing

A team of University of California, Irvine researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds.

Research reveals how skin cells embark on a swift yet elaborate death

Skin is our body's most ardent defender against pathogens and other external threats. Its outermost layer is maintained through a remarkable transformation in which skin cells swiftly convert into squames--flat, dead cells that provide a tight seal between the living portion of the skin and the world outside.

Daily moisturizer does not prevent eczema according to new research

Eczema or atopic dermatitis is a skin condition that causes the skin to become itchy, red, and dry due to inflammation. Most commonly found in babies and children, previous recommendations say that daily moisturizer use is crucial in preventing eczema bouts.

Cancer risk in psoriatic patients

A new study published in February 2020 in the journal JAMA Dermatology reports that there is a 21% increased risk of cancer in patients with psoriasis, but not with psoriatic arthritis alone.

Microbiome in dermis skin layer is the same regardless of age and gender

In the dermis skin layer, the same bacteria are found across age and gender. This has been shown by researchers from the University of Copenhagen in a new study which has studied skin samples from knees and hips.

Researchers investigate methods to 3D bioprint tissues for craniomaxillofacial reconstruction

Seamlessly correcting defects in the face, mouth and skull is highly challenging because it requires precise stacking of a variety of tissues including bone, muscle, fat and skin.

Hokkaido University scientists reveal missing link in rare inherited skin disease

Hokkaido University scientists are getting closer to understanding how a rare hereditary disease impairs the skin's barrier function, which determines how well the skin is protected.

Molecular biologists identify gene that puts brakes on tissue growth

The planarian flatworm is a simple animal with a mighty and highly unusual ability: it can regenerate itself from nearly every imaginable injury, including decapitation. These tiny worms can regrow any missing cell or tissue -- muscle, neurons, epidermis, eyes, even a new brain.

Targeting VEGFA signaling in the epidermis can prevent psoriasis development

Psoriasis is a frequent skin inflammatory disorder affecting 3% of the population. Psoriasis is characterized by hyperproliferation and defect of epidermal differentiation, leading to the scaly appearance of the skin. The psoriasis skin also presents an increase in blood vessels, leading to the redness of the skin lesions and is associated with immune infiltration.
