Treatment with Docosahexaenoic Acid Improves Epidermal Keratinocyte Differentiation and Ameliorates Inflammation in Human Keratinocytes and Reconstructed Human Epidermis Models [PDF]

open access: yesMolecules, 2019
Atopic dermatitis (AD) is a chronic inflammatory skin disease that can cause skin barrier function damage. Although co-incubation with docosahexaenoic acid (DHA) exerts a positive effect on deficient skin models, no studies have investigated the effects ...

Freeze-Fracture Electron Microscopy of In Vitro Reconstructed Human Epidermis [PDF]

open access: yesJournal of Investigative Dermatology, 1990
Epidermis has been reconstructed in vitro by seeding human keratinocytes on a human dermal substrate in an air-exposed culture. The end product has been examined by freeze-fracture electron microscopy, transmission electron microscopy (TEM) of thin sections, light microscopy, and lipid analysis using thin-layer chromatography.

Deletion of TNFAIP6 Gene in Human Keratinocytes Demonstrates a Role for TSG-6 to Retain Hyaluronan Inside Epidermis

open access: yesJID Innovations, 2021
TSG-6 is a soluble protein secreted in the extracellular matrix by various cell types in response to inflammatory stimuli. TSG-6 interacts with extracellular matrix molecules, particularly hyaluronan (HA), and promotes cutaneous wound closure in mice ...

The Anti-Ageing and Whitening Potential of a Cosmetic Serum Containing 3-O-ethyl-l-ascorbic Acid

open access: yesLife, 2021
Skin ageing has many manifestations such as wrinkles, dryness, hyperpigmentation, and uneven skin tone. Extrinsic and intrinsic factors, especially solar ultraviolet light (UVB), contribute to skin ageing; its main features are brown spots, alterations ...
