Prosthesis with neuromorphic multilayered e-dermis perceives touch and pain
Science Robotics, 2018 A multilayered e-dermis allows a prosthesis and an amputee to perceive a range of innocuous and noxious tactile stimuli. The human body is a template for many state-of-the-art prosthetic devices and sensors.

Pre-vascularized dermis model for fast and functional anastomosis with host vasculature
Biomaterials, 2019 Skin engineering for clinical applications has gained numerous advances, however, most of the available dermis substitutes are exogenous matrices acting for a limited time. Indeed, after implantation these matrices need to be colonized by host cells such

Age-related evolutions of the dermis: Clinical signs, fibroblast and extracellular matrix dynamics
Mechanisms of Ageing and Development, 2019 Ageing is today a major societal concern that is intrinsically associated with the increase of life expectancy. Outside the context of severe degenerative diseases that affect the elderly populations, normal visible signs of ageing, notably skin sagging ...

In vivo stiffness measurement of epidermis, dermis, and hypodermis using broadband Rayleigh-wave optical coherence elastography. [PDF]
Acta Biomaterialia, 2022 Traveling-wave optical coherence elastography (OCE) is a promising technique to measure the stiffness of biological tissues. While OCE has been applied to relatively homogeneous samples, tissues with significantly varying elasticity through depth pose a ...

Aging in the dermis: Fibroblast senescence and its significance
Aging Cell, 2023 Skin aging is characterized by changes in its structural, cellular, and molecular components in both the epidermis and dermis. Dermal aging is distinguished by reduced dermal thickness, increased wrinkles, and a sagging appearance.

Life, 2022 Solar elastosis is associated with a diffuse yellow hue of the skin. Photoaging is related to lipid peroxidation leading to the formation of carbonyl groups. Protein carbonylation can occur by addition of reactive aldehydes, such as malondialdehyde (MDA),

Focus on the Contribution of Oxidative Stress in Skin Aging
Antioxidants, 2022 Skin aging is one of the most evident signs of human aging. Modification of the skin during the life span is characterized by fine lines and wrinkling, loss of elasticity and volume, laxity, rough-textured appearance, and pallor.
