This study found that zinc deficiency in goats led to lower plasma zinc levels, decreased growth rate, smaller testicles, reduced libido, and was associated with higher mortality compared to control goats.

In this study, daily topical minoxidil treatment in neonatal hairless pups led to increased hair growth and the development of hair follicles in the treated areas.

In this study, the alcoholic extract DN106212 from Centipeda minima was shown to be more effective in promoting hair growth in C57BL/6 mice compared to dimethyl sulfoxide and tofacitinib, suggesting its potential as a natural hair growth agent.

This study found that the patch assay effectively reconstituted mature hair follicles using culture-expanded human fetal cells and may serve as a method to assess cell trichogenicity.

The authors concluded that dermal white adipose tissue, influenced by factors like light irradiation, plays a significant role in modulating hair follicle cycles and could be targeted for hair growth treatments.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

In this study, topical application of ginsenosides Rb₁ and Rd in mice increased cell proliferation in hair follicles, suggesting they may help prevent hair loss by promoting growth through p63 induction.

This study suggests that ultra-fine powders of steamed and lyophilized mature silkworms may have enhanced pharmacological effects compared to fine powders, possibly due to their smaller particle size.

This study found that transplanted hair follicle-associated pluripotent stem cells in mice differentiated into keratinocytes and stimulated hair growth by producing mature hair shafts.

This article reviews the use of autologous platelet-rich plasma (PRP) in hair restoration, discussing its potential benefits for follicle health and regeneration, but it reports no new clinical findings.

This case report describes the histopathological features of nevus psiloliparus in an 11-year-old girl, noting "shadow" follicular units with loosely arranged collagen and reduced elastic fibers.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

Stem cells in developing hair follicles move to specific areas as they mature.

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 describes the development of a new embryonic stem cell culture system that allows for the differentiation into mature hair follicle cells, potentially aiding research in hair follicle formation and regeneration.

In this study, researchers explored hair follicle development in Qianhua Mutton Merino sheep, identifying key genes like KRT27 and IGF-2 that impact this process, with findings suggesting significant molecular changes as sheep mature from newborn to one year old.

This study found that organoid cultures of human epithelial and mesenchymal cells can produce hair peg-like structures, and their growth is enhanced by minoxidil, suggesting potential for hair drug screening.

This study found that transplanting genetically modified dermal fibroblasts into full-thickness skin defects in rats led to the formation of hair follicles with mature pilosebaceous systems by 16 weeks.

In this study, epidermal growth factor (EGF) was shown to increase the length of rat organ of Corti segments containing supernumerary hair cells, with the effect peaking at birth and independent of cell division.

This study found that treating rat whisker follicle stem cells with retinoic acid and epidermal growth factor induced them to express synaptophysin, a marker of mature neurons, although there was a reduction in other neural markers, suggesting potential for neuro-regeneration applications.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

This study found that in mice, epidermal Wnt/β-catenin signaling influences adipocyte differentiation and hair growth, suggesting its critical role in synchronizing adipogenesis with the hair growth cycle.

This study developed an antimicrobial microneedle patch for delivering apoptotic vesicles to treat infected wounds, which was found to effectively reduce bacterial growth and accelerate scarless healing, including the rapid formation of mature hair follicles in just 8 days, a previously unreported early outcome.

This review addresses the role of biotin in animal metabolism, emphasizing the need for further research to understand its dietary and microbial sources in different developmental stages in pre-ruminant and mature ruminant animals, without reporting new experimental results.

This study found that glioblastoma cancer stem cells avoid immune suppression by downregulating TLR4, and restoring TLR4 signaling may reduce tumor growth and self-renewal.

This study found that activin B promotes the initiation and development of hair follicles in both cultured and neonatal mouse skin models.

This study found that zinc methionylglycinate supplementation improved haircoat characteristics and zinc absorption in dogs compared to zinc sulfate.

This review article evaluates the effectiveness of autologous fat transplantation in regenerative medicine and rejuvenation, highlighting its biocompatibility and non-immunogenic properties as a facial filler, and notes the variable outcomes based on adipose tissue size.

This article reviews the morphogenesis and cycling of hair follicles and the complex signaling pathways involved, without reporting new experimental results.
