This study developed a bilayer bionic skin scaffold that mimics the skin's structure to resist microbial invasion and enhance wound healing, with in vivo animal studies showing improved collagen deposition, neovascularization, and hair follicle formation.

This study found that Alpha Lipoic Acid may help reduce cigarette smoke-induced skin damage in rats by improving collagen structure and reducing markers of oxidative stress.

This study observed that Fraser’s dolphins exhibit remarkable skin healing abilities, with type I collagen prevalent in normal skin and type III collagen emerging during early wound healing before returning to normal configuration, suggesting insights for human clinical wound management.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This chapter discusses various aspects of collagen, proposing "extended collagen carential disease" as a new concept tied to nutritional deficiencies, notably Vitamin C's role in maintaining collagen health.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

This study found that in a mouse model, alopecia areata was associated with changes in heart structure, biochemistry, and gene expression linked to cardiac hypertrophy after ACTH exposure.

This study developed a protocol for acellular dermal matrix manufacturing from pig skin, demonstrating effective removal of cellular components while preserving the collagen scaffold's structural organization through a series of physical and chemical treatments.

This study found that hyperbaric oxygen treatment in rats led to structural changes in epidermis and dermis, including decreased E-cadherin expression and increased connective tissue.

This study found that Raman spectroscopy has potential for detecting biophysical differences in basal cell carcinoma compared to normal skin structures, supporting its future use in Mohs surgery.

This study found that while short-term use of PEG-400 and Thiazone affected rat skin structure, the changes were reversible with no long-term effects observed.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This study applied a new RGB trichrome stain to human skin samples, revealing distinct structural staining in normal tissues and potential proteoglycan-rich zones in hair follicles.

This study reported that a skin equivalent model using human outer root sheath cells and fibroblasts showed the formation of structures similar to human dermis and epidermis within two weeks after transplantation into mice.

This study found that murine epidermal stem cells implanted subcutaneously in a biodegradable carrier could survive and differentiate into structures resembling native dermis without significant rejection in recipient mice.

This discussion of age-related changes in female scalp hair follicles reports no new results, highlighting the structural transformations that may contribute to thinning hair in women as they age.

This study suggests that the phenotype of melasma in women is influenced by structural and cellular changes across the epidermal-melanin unit, not just melanocyte hypertrophy, highlighting potential roles for dermal damage repair and fibroblast senescence.

This article reviews how biopolymers are utilized in cosmetics, highlighting their biodegradable and non-toxic properties, recent structural developments, novel applications, and safety considerations in the formulation of skin, hair, and oral care products.

In this study, researchers identified a collagen fragment, sample-1707, expressed in E. coli, which forms nanofibers and promotes blood clotting, osteoblast differentiation, and skin cell regeneration, making it a promising biomaterial for skin care, with a large-scale production yield of 600 mg/L.

This review explores the physiological roles of collagen XVII in the epidermis, its involvement in stem cell maintenance, and its connections with signaling pathways, but it reports no new results.

In this study, microporous electrospun scaffolds pre-seeded with dermal fibroblasts accelerated wound healing and improved dermal matrix structure and hair follicle regeneration compared to acellular scaffolds in a rat model.

This study found that dermal sheath stem cell characteristics are lost with aging in humans, affecting skin rejuvenation and structure, and identified specific proteins like Activin A influencing keratinocyte and fibroblast activity.

This study found that dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.

In this study, cultured skin equivalents with ovine hair follicle dermal papillae grafted onto nude mice developed follicle-like structures, suggesting a potential model for studying hair follicle development.

This study reported that human induced pluripotent stem cell-derived skin organoids, used to model epidermolysis bullosa, have an epidermal-dermal junction largely lacking type VII collagen, which is important for skin structure.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This study found that wounds in sheep treated with mesenchymal stem cells and platelet-rich plasma showed improved healing, reduced inflammation and contraction, and better skin structure compared to untreated wounds.

Collagen XVIII and Bmx tyrosine kinase are important for hair growth and skin cancer development.

In this study, researchers developed a composite electrospun dressing with fiber gradient changes that mimics skin's natural structure, demonstrating enhanced wound healing, collagen deposition, and reduced fibrosis and scarring in both in vitro and in vivo experiments.
