A Chronic Wound Model to Investigate Skin Cellular Senescence

A Chronic Wound Model to Investigate Skin Cellular Senescence

Posted on by skin_challenges
Wound healing is an essential physiological process for restoring normal skin structure and function post-injury. The role of cellular senescence, an essentially irreversible cell cycle state in response to damaging stimuli, has emerged as a critical mechanism in wound remodeling. Transiently-induced senescence during tissue remodeling has been shown to be beneficial in the acute wound…

Evolution of the Facial Skin Microbiome During Puberty in Normal and Acne Skin

Evolution of the Facial Skin Microbiome During Puberty in Normal and Acne Skin

Posted on by skin_challenges
The composition of the skin microbiome varies from infancy to adulthood and becomes most stable in adulthood. Adult acne patients harbour an ‘acne microbiome’ dominated by specific strains of Cutibacterium acnes. However, the precise timing of skin microbiome evolution, the development of the acne microbiome, and the shift to virulent C. acnes strain composition during puberty is unknown. Schneider…

Researchers use skin-colonizing bacteria to create a topical cancer therapy in mice

Researchers use skin-colonizing bacteria to create a topical cancer therapy in mice

Posted on by skin_challenges
In a study led by Stanford Medicine, researchers harnessed the skin’s immune response to bacteria to create an immunotherapy — delivered by swab — that treats aggressive tumors in mice. While studying a type of bacteria that lives on the healthy skin of every human being, researchers from Stanford Medicine and a colleague may have stumbled on…

A Novel Hybrid Artificial Neural Network Technique for the Early Skin Cancer Diagnosis

A Novel Hybrid Artificial Neural Network Technique for the Early Skin Cancer Diagnosis

Posted on by skin_challenges
Tajjour et al. used an innovative hybrid machine learning-technique for the early skin cancer diagnosis fusing Convolutional Neural Network and Multilayer Perceptron to analyze images and information related to the skin cancer. This information is extracted manually after applying different color space conversions on the original images for better screening of the lesions. The proposed…

Scientists develop novel mRNA delivery method using extracellular vesicles

Posted on by skin_challenges
Representative Masson trichrome collagen staining of the epidermis, dermis and subcutis for all mouse groups.  A team of researchers led by The University of Texas MD Anderson Cancer Center has developed a novel delivery system for messenger RNA (mRNA) using extracellular vesicles (EVs). The new technique has the potential to overcome many of the delivery hurdles faced…

Getting under your skin for better health

Getting under your skin for better health

Posted on by skin_challenges
A prototype of a device that can measure interstitial fluid uses microneedles.  The next frontier of continuous health monitoring could be skin deep. Biomedical engineers at the University of Cincinnati say interstitial fluid, the watery fluid found between and around cells, tissues or organs in the body, could provide an excellent medium for early disease…

A Novel Sprayable Treatment for Wound Healing

A Novel Sprayable Treatment for Wound Healing

Posted on by skin_challenges
Liu et al. established a novel sprayable adhesive (ZnMet-PF127) by the combination of a thermosensitive hydrogel (Pluronic F127, PF127) and a coordination complex of zinc and metformin (ZnMet).  They demonstrated that ZnMet-PF127 potently promotes the healing of traumatic skin defect and burn skin injury by promoting cell proliferation, angiogenesis, collagen formation. ZnMet also turned out…

“Unexpected” – Scientists Discover an Anti-Aging Mechanism

“Unexpected” – Scientists Discover an Anti-Aging Mechanism

Posted on by skin_challenges
The mechanism extends the life of the immune system.  A multinational team headed by University College London scientists has discovered a new mechanism that slows down and maybe even prevents the normal aging of immune cells, one of the nine “hallmarks of aging.” The discovery in-vitro (cells) and validated in mice was “unexpected,” according to the researchers,…

Extracellular Vesicles Derived from Pinctada martensii Mucus Regulate Skin Inflammation

Extracellular Vesicles Derived from Pinctada martensii Mucus Regulate Skin Inflammation

Posted on by skin_challenges
Extracellular vesicles (EVs) and their exosome subsets are vesicle-like nanoparticles that are secreted by cells and contain various factors that treat various diseases. Wu et al.  isolated EVs from the marine shellfish Pinctada martensii mucus and studied the efficacy of those EVs in modulating the inflammatory environment. A human skin inflammatory cell model was established to…
