Evaluating the Expression of Mesenchymal Stem Cells Markers in Human Hair Follicle Stem Cells

Journal of Ardabil University of Medical Sciences, 2014
Background & objectives: Adult stem cells are undifferentiated cells that replace dead or injured cells. There are adult stem cells in some regions of human tissues and hair follicle is one of the tissues that have adult stem cell source and these cells ...

Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

High Uric Acid Promotes Stem Leydig Cell Senescence by CCDC90B Mediates Mitochondrial Quality Control Imbalance

Cell Proliferation, EarlyView.
In hyperuricemia, uric acid inhibits CCDC90B ubiquitination degradation by binding to it. Excessive CCDC90B induces mitochondrial calcium overload, leading to mitochondrial quality control imbalance and ultimately resulting in SLC senescence and decreased testosterone levels.

In vivo differentiation of scarring alopecia using line‐field confocal optical coherence tomography: a pilot study

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and Objectives: Diagnosing cicatricial alopecia is challenging. Even with histology, a definitive diagnosis cannot always be made. Line‐field confocal optical coherence tomography (LC‐OCT), a non‐invasive imaging method with high resolution used in vivo, has proven helpful in diagnosing scarring alopecia.

Early On‐Treatment Change in SALT as a Pragmatic Predictor of Ritlecitinib Response in Moderate‐To‐Severe Alopecia Areata: A Real‐World Cohort Study

International Journal of Dermatology, EarlyView.
Ritlecitinib induced rapid clinical improvement in moderate‐to‐severe alopecia areata in real‐world practice. Early change in SALT at Week 12 strongly discriminated Week‐24 responders, supporting a pragmatic treat‐to‐target checkpoint, alongside improvements in clinician‐reported and patient‐reported outcomes and a favorable safety profile.

Melatonin-Mediated Circadian Rhythm Signaling Exhibits Bidirectional Regulatory Effects on the State of Hair Follicle Stem Cells

Biomolecules
The development and regulation of hair are widely influenced by biological rhythm signals. Melatonin plays a crucial role as a messenger in transmitting biological rhythm signals, and its impact on hair development has been well documented.
