This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

In this study, researchers found that glycan profiles in epidermal stem cells differed between young and old mice, suggesting these changes may serve as molecular markers for aging.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This study examined the molecular communication in psoriasis cells, highlighting unique immune cell interactions and identifying new features of the hair follicle cell-psoriasis axis. It suggests the potential for targeted therapies at the single-cell level to improve psoriasis treatment.

This study highlighted the significance of integrating single-cell RNA sequencing with spatial transcriptomics for improving cell-type identification in human skin, emphasizing the need for a comprehensive cell atlas.

This review summarizes recent research on the molecular properties and functions of L-PGDS and PGD2, but reports no new findings, highlighting their pathophysiological roles and guiding future studies.

This study identified significant gene expression differences in human basal cell carcinoma, including up-regulation of zinc finger encoding genes, which are not entirely reflected in current mouse models.

This study found that RCS-01 cell therapy for aged skin was well tolerated and associated with increased gene expression related to extracellular matrix homeostasis, suggesting potential skin improvement.

Keratins are crucial for cell structure, growth, and disease risk.

This study found that keratin 19, unlike keratin 14, forms less stable filaments with keratin 5, suggesting distinct assembly properties and potential unique roles in skin basal cells.

This study found that L-type channel blockers can induce hair growth in Timothy syndrome by overcoming delays in anagen phase, suggesting a potential therapeutic role for tissue regeneration.

This study examined immune responses to Diphencyprone and found that its induced skin reactions have higher levels of negative immune regulators compared to psoriasis, suggesting differences in immune regulation may contribute to psoriasis chronicity.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This review explores different types of alopecia, the effects on hair appearance and growth, and the conventional treatments available, including minoxidil and finasteride, along with their side effects and the need for future drug development and potential therapies.

In this study, a silk fibroin hydrogel containing recombinant NT3 was found to promote scar-less wound healing in a mouse skin injury model by enhancing type III collagen expression and inducing hair follicle formation.

This study identifies Activin A and follistatin as key regulators of hair cell differentiation in the mouse auditory sensory epithelium, influencing the timing and pattern of hair cell development.

This study provided a dynamic 4D atlas showing the development process of mouse hair follicles through a telescope-like model, revealing new insights into the origin of hair follicle stem cells.

This study found that serine 44 in the N-terminal head domain of keratin 17 is phosphorylated in response to various stimuli affecting skin keratinocyte growth, linking K17 up-regulation with growth and stress responses in skin epithelium.

This study found that COL17 deficiency in neonatal mice causes abnormal skin cell proliferation due to disrupted Wnt signaling, while replenishing or overexpressing COL17 can reverse this effect in both neonatal and aged skin.

Growth factors can either promote or inhibit hair follicle cell growth and collagen breakdown.

This preliminary study suggests that Raman micro-spectroscopy can help differentiate basal cell carcinoma from hair follicles in skin tissue sections, although some misclassification of hair follicles as carcinoma was observed.

In this mouse study, NF-κB was shown to play a role in hair follicle cycling and morphogenesis, with specific activity patterns differing by hair type and involving noncanonical signaling for zigzag hair bending.

This study found that most completely excised basal cell carcinomas in the head and neck were nodular, with a 2.7% recurrence rate, particularly in median areas, likely due to anatomical and histopathological factors.

This article reviews how aging affects skin and stem cells, but it contains no new research findings.

Ent-kaurane-type diterpenoids from Isodonis Herba may promote hair growth by boosting cell proliferation.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

This study observed that basal cell carcinoma on the scalp shares more similar characteristics with truncal lesions than facial lesions, despite the scalp's proximity to the face.

In this study, the type II subunit of porcine hair keratin was found to significantly inhibit the differentiation of PC12 neural cells compared to the crude extract and type I subunit, although cell proliferation was unaffected.

In their research, Yucel and colleagues found that CaV1.2 is expressed in hair follicle stem cells, facilitating anagen re-entry in a way not dependent on calcium flux.

This study found that the type 2 cytokines IL-4 and IL-13 may amplify Staphylococcus aureus-induced inflammation and barrier disruption in atopic dermatitis, potentially worsening skin defense against this bacterium.
