Hair follicle samples effectively show how well the drug MK-0752 targets and engages with the Notch pathway.

This study reported a case where cyclosporine treatment in a child led to remission of ulcerative colitis and regrowth of scalp and body hair, suggesting a possible connection between the disorders.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.

This study found that acanthosis nigricans and skin tags in nondiabetic, obese patients were significantly associated with higher insulin levels, suggesting they may serve as clinical markers of hyperinsulinemia.

This minireview discusses a proposed model of the vitamin D receptor that explains how 1alpha,25(OH)2D3 can mediate both genomic and rapid responses through different ligand shapes and cellular locations, without presenting new research findings.

This study reports that three synthesized PSMA-targeted radioimaging agents demonstrated high affinity and specific localization to prostate cancer tumors in a mouse model, highlighting their potential for cancer detection and monitoring.

This study found that dyed chitin nanofibers maintain color and mechanical properties when reinforcing resins, allowing color addition and strength improvement while retaining transparency.

This review summarizes the proposed model that describes how different shapes of 1alpha,25(OH)2D3 ligands interact with the vitamin D receptor to mediate genomic and rapid responses in cells.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

This review discusses manipulating the stem cell niche as a strategy in regenerative medicine to repair damaged tissues, highlighting the potential benefits and challenges but reporting no new results.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This review provides an in-depth analysis of the structure and function of c-kit activation, and its role in both normal physiological and pathological conditions, with no new research findings reported.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.
