This review highlights the potential of amphiregulin as a therapeutic target, noting its role in both fibrotic and malignant diseases, and discusses promising early findings but reports no new clinical results.

This study found that hyperproliferative stimuli dysregulated the balance of stem cell divisions in keratinocytes, suggesting potential treatment strategies for both benign and cancerous hyperproliferative diseases.

This study demonstrated that the highly divergent WDSV rv-cyclin significantly stimulates eukaryotic cell proliferation, leading to hyperplastic skin lesions in transgenic mice.

This review examines how caloric restriction could promote autophagy to rejuvenate aging stem cells, though the precise molecular mechanisms remain unclear.

In this study, a subcutaneous injection of recombinant RSPO1 was found to activate hair follicle stem cells and enhance hair regeneration in mice by stimulating the Wnt/β-catenin signaling pathway, suggesting its potential as a treatment for hair loss.

This review summarizes recent insights into corneal limbal stem cell differentiation and the potential role of progenitor-like cells, but reports no new experimental results.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study found that transfollicular delivery using surfactant-based nanoparticles significantly enhanced antigen stability and immune response compared to other delivery methods, especially when combined with an adjuvant.

In this study, sandalore was found to activate OR2AT4, which inhibits senescent cell traits and restores proliferation in human keratinocytes, suggesting potential anti-aging applications.

This study found that thymic stromal lymphopoietin (TSLP) promotes hair growth after skin injury by enhancing the proliferation of specific stem cells in hair follicles.

This study found that vanillic acid from wheat bran promoted dermal papilla cell proliferation, potentially stimulating hair growth by activating the PI3K/Akt and Wnt/β-catenin pathways.

This study found that limonin may promote hair growth by enhancing anagen signaling through autophagy activation in rat dermal papilla cells, suggesting its potential as a natural treatment for hair loss.

AMP-303 injections can increase hair growth in androgenetic alopecia with minimal side effects.

This study in mutant mice found that Bmpr2 and Acvr2a are individually redundant, but together essential for normal hair follicle development, with their reduction causing rapid hair cycling and graying.

This study found that EGR1 promotes the proliferation of dermal papilla cells, suggesting its close association with hair follicle growth and development.

This study found that JUNB enhances hair regeneration in mice by promoting dermal papilla cell proliferation through the Wnt signaling pathway, suggesting JUNB as a potential molecular target for improving cashmere quality and breeding in cashmere goats.

In this study, researchers found that the thyroxine receptor agonist TDM10842 accelerated the onset of anagen, a hair growth phase, in C3H mice, potentially through activation of the Wnt/beta-catenin and Hedgehog pathways, with Pclaf playing a key role in this process.

This review highlights the critical role of microRNAs in regulating hair follicle biology, significantly impacting wool and cashmere development by modulating gene expression and signaling pathways in sheep and goats.

This study found that, despite confirming MC1R expression and functional cAMP signalling, α-MSH treatment did not alleviate UVA-induced stress in adult dermal fibroblasts, suggesting that α-MSH-MC1R may not directly protect against UVA-induced photoaging in these cells.

This study discovered that calcium dependent protein kinase 1 (CPK1) directly activates cyclic nucleotide-gated channels 5, 6, and 9, promoting root hair growth in Arabidopsis by regulating Ca²⁺ signaling.

This study found that costunolide promotes hair growth in both lab-cultured human hair follicle cells and in live mice by modulating growth factor pathways.

This study found that LEF-1 expression influences dermal papilla cells' proliferation through Wnt signaling, impacting the potential for cashmere yield improvement.

In this study, researchers presented cases of cellular neurothekeoma in three male family members with early-onset in infancy, suggesting a potential genetic component and inheritance pattern, which deviates from the typical presentation seen mostly in women between 20–30 years.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

This study found that oral administration of Terminalia bellirica enhanced hair growth in testosterone-suppressed conditions in both human cell and mouse models, outperforming finasteride, a current commercial hair loss treatment.

In this narrative review, researchers synthesized current evidence on topical metformin's potential benefits for various skin conditions, citing primarily preclinical studies that highlight its anti-inflammatory, antioxidant, and regenerative properties, although clinical translation requires further rigorous trials.

This study found that the lncRNA lncRNA2919 is involved in hair follicle regeneration by downregulating growth-related genes, inhibiting cell proliferation, and promoting apoptosis in rabbit dermal papilla cells.

This study found that using an aqueous solution of AMPD in hair bleach reduced both hair damage and odor compared to ammonium hydroxide.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.
