This study found that alopecia in VDR-null mice persists despite undetectable vitamin D levels, indicating a defect in epithelial-mesenchymal communication due to the absence of ligand-independent receptor function.

In this review, the authors explored the diverse roles of fibroblasts in wound healing, suggesting that understanding their complexity could lead to better insights into wound pathologies and the development of new treatments.

This study observed that after hair cell loss in the mouse cochlea, supporting cells were replaced by migrating non-specialised cells, with genetic background affecting the rate of tissue re-organization.

This review discusses the potential of adipose-derived tissue components like nanofat and stem cells for aesthetic rejuvenation, covering their use in hair growth, scar reduction, and more, without reporting new clinical results.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study reports that topical minoxidil led to normalization of hair follicle characteristics in 36 of 47 severe alopecia areata patients, and indicated a shift in T cell populations, suggesting potential immunomodulatory effects.

This study identified 12 new genes associated with the hair follicle and various stages of the hair cycle in mice, which could lead to novel targets for hair growth or depilation therapies.

This study found that monocytes/macrophages with a pro-inflammatory M1-like phenotype may play a crucial role in the pathogenesis of hidradenitis suppurativa, suggesting potential therapeutic targets.

This study found that keratinocyte growth factor is a potent mitogen in human hyperplastic prostate cells, suggesting it plays an important role in prostate growth by acting in a paracrine manner.

In this study, blue light-irradiated nanovesicles derived from human adipose-derived stem cells enhanced dermal fibroblast proliferation and extracellular matrix synthesis, improving skin maintenance and hair follicle regeneration, suggesting a novel therapeutic strategy for skin and hair disorders.

This review discusses cellular senescence in relation to ALS and explores how targeting senescent cells could potentially serve as a treatment strategy, but it reports no new clinical findings and emphasizes that this link is not yet conclusively established.

In this study, researchers evaluated the hair growth-promoting effects of strawberry water-extract on human follicle dermal papilla cells and found it enhanced cell metabolism, though it did not significantly alter hair growth-related gene expression.

This study found that in spiny mice, the proximal side of ear wounds is crucial for regeneration, a process possibly linked to unique injury-induced immune responses compared to nonregenerative rodents.

In this study, researchers explored the molecular and cellular traits of avian reticulate scales, finding that they lack localized stem cell niches for regeneration, unlike other scale types, leading to repair but not regeneration after wounding.

In this study, the researchers cloned and analyzed the CRABP I gene in Inner Mongolian cashmere goats, finding its highest mRNA expression at 90 days in embryo skin compared to later stages.

In this study, the methanolic extract of Tridax procumbens Linn demonstrated significant antiulcer activity in a mice model of acetic acid-induced ulcerative colitis, offering 57.12% ulcer protection compared to 50.60% by the standard drug prednisolone.

In this study, researchers used single-cell RNA sequencing to map the hair follicle microenvironment in fine-wool sheep, identifying specific cell types and gene expressions that influence wool fiber diameter, with dermal papilla cells playing a significant role in hair follicle development.

This mini-review explores how both endogenous and damage-released RNAs serve as instructional signals that influence cell identity and plasticity during tissue maintenance and repair, highlighting RNA's role as a regulator of cellular flexibility in various regenerative contexts.

This study found that cold exposure disrupts the circadian rhythm in cultured human cells by reducing oscillation amplitude, which is restored upon rewarming, while human hair follicle cells showed minimal amplitude sensitivity to temperature changes, suggesting an evolutionary advantage related to Hopf bifurcation dynamics.

This review explores the potential benefits of natural plant-based products for skin anti-aging, assessing effects on wrinkles, oxidative stress, pigmentation, and hydration, while also underscoring the importance of lifestyle factors such as diet, exercise, and sleep in skin health maintenance.

This review found that adipose-derived stem cells and stromal vascular fraction have robust clinical benefits in aesthetic surgery, particularly in facial rejuvenation, scar treatment, and volumetric restoration, with favorable safety profiles.

This literature review discusses the challenges and potential strategies for creating fully functional hair follicles capable of active cycling, emphasizing the molecular mechanisms, signaling pathways, and innovative regenerative techniques, such as hair micropatterning and three-dimensional printing, crucial for optimizing hair follicle regeneration.

Cell movements and forces shape feather growth in chicken skin.

This study provided new insights into the complex and heterogeneous architecture of keratin filaments, revealing their dynamic and flexible structure through cryo-electron microscopy analysis.

In this clinical study of 98 patients with focal alopecia, combined laser therapy, which included laser plasma therapy and percutaneous laser irradiation of blood, was reported to alleviate inflammation, promote hair growth, and restore trace elements in affected areas.

This research found that human adipose stem cells maintained their immaturity and potential to differentiate into beige adipocytes in an endothelial growth medium, correlating with increased SOX2 expression linked to beige and brown adipocyte activation.

In this study, Mononuclear Cells provided site-specific protection against chemotherapy-induced alopecia in rats treated with Ara-C, but not with CTX or VP-16, while PRP showed no protective effect.

This study suggests that sirolimus and propranolol may reduce abnormal lymphatic endothelial cell proliferation in lymphatic malformations, potentially improving vessel function and patient outcomes.

This study identifies unique gene expression patterns in specialized fibroblasts within adult hair follicles, which advances understanding of their role in tissue regeneration.
