The researchers developed a new follicular unit extraction system with adjustable needle lengths and precise rotation speed, which they report as being superior to existing systems for non-incisional hair transplants.

This study developed a rapid ATP assay that effectively measures microbial populations on the skin and tracks changes after microbiome dysbiosis, with findings suggesting that ethanol-cleansed skin takes longer to recover than tape-stripped skin.

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

This study found that the development and differentiation of Merkel cells in C57BL mouse embryos' dorsolateral skin are linked to tylotrich follicle formation rather than to neural influences.

EGF and FGF signaling stops hair follicle development in mice.

This study reports that PADI4, an enzyme involved in posttranslational protein modifications, regulates progenitor cell transitions in hair follicle development by repressing transcription and interacting with translational and ribosomal processes.

This study identified epiprofin as a highly tissue-specific nuclear protein that promotes cell proliferation, mainly expressed in the developing teeth, hair follicles, and limbs of embryonic mice.

This study found that CTCF is crucial for proper skin and hair follicle development in mice, affecting keratinocyte differentiation and gene expression in keratin loci.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

In this study, using a 3D culture model, researchers observed that developmental stage and androgen levels influenced murine follicle growth, which may inform treatment for women with low ovarian reserve but cautions against excessive androgen exposure.

This study found that the HoxC gene cluster plays a critical role in the development of ectodermal organs, including hair and nails, with mammalian-specific enhancers increasing transcription levels during development.

This study characterizes gene expression patterns in embryonic hair follicle progenitors and their niche, identifying signaling pathways like axon guidance that may drive cellular rearrangements for hair follicle formation.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This study provides a comprehensive platform to explore stem cell interactions regulating hair follicle growth, revealing key signaling pathways in epithelial-mesenchymal interactions using advanced RNA sequencing and transgenic reporters.

This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.

Developing human skin has immune cells with memory-like features.

Caspase-7 has functions in skin and hair that are not related to cell death.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This abstract reviews recent findings on the biology of isolated micrografts in hair restoration, emphasizing factors that enhance micrograft viability, but it does not report new experimental results.

In this study, researchers identified unique prenatal lymphocyte features in human fetal skin, including proliferative naive T cells and memory-like T cells, which may influence antigen and allergen responses in utero and infancy.

This thesis explores how optical coherence tomography and advanced imaging methods may address clinical needs in fields like interventional pulmonology and dermatology, highlighting their potential for disease assessment and staging.

This study developed a new human hair research model combining 3D spheroid dermal papilla fibroblasts with plucked anagen hair shafts, potentially improving the evaluation of hair follicle differentiation.

This chapter reports an organ culture method that permits mouse embryonic skin tissues to develop similarly to in vivo conditions, revealing that epidermal growth factor inhibits hair follicle formation.

This review discusses the role of Wnt/β-catenin signaling in hair follicle regeneration and highlights recent progress in developing hair loss treatments targeting this pathway, but reports no new clinical results.

This review highlights the potential role of mathematical and computational approaches in enhancing and accelerating the clinical translation of regenerative medicine products but reports no new clinical findings.

This study found that cortisol and corticosterone led to thinning of the epidermis and hair follicle regression in fetal mouse skin, while testosterone promoted differentiation and sebaceous gland development.

This study found that the progression of fetal skin development, marked by key features like the appearance of hair follicles and eccrine sweat glands, can help determine fetal age and predict congenital skin diseases.

This study found that cellular retinoic acid-binding proteins and fatty acid-binding proteins are dynamically expressed in skin development and respond differently to retinoic acid, β-catenin, and Notch signaling.

This review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.
