In this study, male rats exposed in utero to low-dose chemical mixtures had permanent reproductive tract alterations, suggesting additive effects even at doses below individual adverse levels.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

This study found that temperature affects the influence of daylength on prolactin secretion and hair growth in dairy goats, without significant involvement of melatonin.

This study observed morphological changes in scalp hair follicles of humans deprived of protein for 15 days, which suggests potential use in diagnosing protein-calorie malnutrition.

This study demonstrated that OSA hydrogels enhanced the stability and retention of dermal papilla-derived extracellular vesicles, which significantly improved hair regeneration in both cultured human hair and a mouse depilation model.

In this study, murine follicular cell aggregates developed into hair-like structures in culture, which upon implantation into mice skin matured into complete hair follicles, suggesting potential for treating hair loss.

This study found that hydroxysafflor yellow A-rich Carthamus tinctorius extract promoted hair growth and gene expression linked to hair proliferation in both cell cultures and mouse models.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

This study found that in androgenetic alopecia, reduced stem cell factor production by dermal papilla cells may lead to decreased pigmentation in hair follicles.

In this study, the RADA-PRG hydrogel enhanced SKP proliferation, survival, and gene expression, effectively supporting hair follicle regeneration in mice.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

The study observed that finasteride reduced fertility in male Sprague-Dawley rats by impairing the formation of copulatory plugs, an effect considered specific to rats and not applicable to species without this reproductive feature.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.

This study observed that rat vibrissa hair follicles cultured in vitro showed morphological changes suggesting cyclical activity but remained blocked in the pro-anagen stage.

This study found a significant shift to the telogen phase in the hair growth of children with classical marasmus compared to normal children, suggesting a connection to the chronicity of the condition.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

This study demonstrates that incorporating human neopapilla into reconstructed human skin can initiate hair follicle morphogenesis by stimulating epidermal invagination and maintaining follicle-inductive properties in vitro.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

In this study, Wnt-10b was found to promote hair follicle development and hair growth in cultured mouse embryonic skin and transplanted skin in nude mice.

This study found that selecting human hair follicles at a defined anagen stage based on their in vivo growth rate leads to more consistent results in organ culture, with minoxidil significantly enhancing hair growth in these follicles.

This study found that l-carnitine stimulated hair growth in vitro by promoting proliferation and reducing apoptosis in human scalp hair follicles, suggesting potential as a treatment for hair loss.

This study found that macrophage-stimulating protein (MSP) enhanced hair growth in both human hair follicles cultured in vitro and in mice through the promotion of anagen phase induction.

This study found that dermal papilla cells cultured in vitro can promote hair follicle regeneration and maintain hair growth, with stronger ET-1 and SCF expression enhancing this regenerative ability.

This study found that dihydrotestosterone induced hair loss and changes in hair morphology in male C57BL/6 mice, effects that could be partially reversed by the AR antagonist bicalutamide.

In this study, DHT was observed to have varying effects on hair follicle growth and related protein expression depending on concentration, with the Wnt/β-catenin pathway potentially playing a significant role.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that adipose-derived mesenchymal stem cells from type 2 diabetes mice were slightly less effective, yet had comparable therapeutic effects on wound healing compared to non-diabetic controls.
