This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This monograph reviews the significant progress in skin biochemistry research over eight to ten years, highlighting key areas and identifying gaps in interpretation.

This article reviews the digitization of historical issues of the Journal of Investigative Dermatology, highlighting the impact and citation durability of its 1970 publications; it reports no new clinical results.

This article discusses the role of clinical observation and microscopic correlation in American dermatology training and reports no new clinical results.

This article provides a comprehensive review of ichthyoses, including their classification, biochemistry, associated syndromes, and therapeutic approaches, but reports no new clinical findings.

This review discusses the history, structure, and biological significance of keratins, including the crystal structure of a keratin helical segment, without reporting new experimental results.

In this study conducted at the Veterinary Clinical Complex in Bikaner, Rajasthan, researchers found that among 240 canine dermatitis cases, 25 dogs had demodicosis, characterized by various hematological and serum biochemical changes, and distinctive histopathological alterations in skin samples.

This study suggests that vitamin D and calcium signaling play a crucial role in wound healing by regulating stem cell activation through enhanced β-catenin transcriptional activity in mice.

This study reports that EGF at specific concentrations promotes the proliferation and migration of hair follicle ORS cells by activating the Wnt/β-catenin signaling pathway in vitro.

In this study, researchers purified and cloned rat peptidylarginine deiminase type III, demonstrating its activity and specific expression in the epidermis and hair follicles.

Glucocorticoid receptors help regulate genes important for skin health and hair growth.

In this case-control study, EGF levels were significantly higher in patients with alopecia areata than in healthy controls, and these elevated levels positively correlated with the severity and extent of the disease, suggesting EGF as a potential marker for alopecia areata severity.

This study found that deleting the vitamin D receptor from specific stem cells in mouse hair follicles disrupts their ability to regenerate the epidermis after injury, suggesting an essential interaction with the transcription factor p63.

This study found that mice lacking both vitamin D and calcium-sensing receptors in epidermal keratinocytes are predisposed to developing squamous cell carcinoma as they age, due to impaired oxidative stress response and reduced DNA repair capabilities.

This study localized Merkel cells in human skin, finding them in the basal layer of glabrous skin at palms and soles, and in the interfollicular epidermis and isthmus region of hair follicles.

This study highlights the complex role of the vitamin D receptor in skin processes, where its disruption, along with calcium and co-regulator imbalances, could contribute to skin cancer development by altering skin differentiation and hair follicle cycling.

Androgens don't directly affect hair cell growth or protein production.

This study found that UVB irradiation alters skin stem cell niches leading to signs of photoaging, which may be reversed by adipose-derived stem cells through BMP4 pathway modulation and niche remodeling.

In this study investigating canine pyoderma, the researchers found that Staphylococcus species isolated from 57 dogs were most sensitive to the antibiotic Linezolid, with a 100% sensitivity rate, followed by other antibiotics like Doxycycline hydrochloride and Cefpodoxime.

This study found that while calcium can substitute for the Vitamin D receptor in maintaining epidermal keratinocyte differentiation, it cannot compensate for hair follicle dysfunction caused by the absence of the receptor.

This study found that deleting β-catenin in epidermis-specific VDR knockout mice did not prevent UVB-induced skin tumors, indicating β-catenin does not compensate for VDR's role in tumor suppression.

This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This review discusses the role of acyl-CoA binding protein (ACBP) in the epidermal barrier, noting that its disruption in mice is linked to skin and fur abnormalities; it reports no new clinical results.

The study observed that mRAGE expression is prevalent in keratinocytes of the healthy human epidermis and may regulate inflammation and apoptosis to maintain skin homeostasis rather than responding to aging processes.

Minoxidil promotes hair growth by increasing cell division and DNA synthesis.

In this study, BLIMP1 was found to function in terminally differentiated epidermal cells to maintain homeostasis, rather than defining a sebocyte progenitor population.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.
