This study found that hair curvature in merino wool is influenced by differences in cell type length rather than the proportions of orthocortical and paracortical cells.

In this study, the bending stiffness of human hair was linked to the varying proportions of para-like versus ortho-like cortical cells within the hair fiber.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study found that the curl in hair is due to the arrangement of different cell types, with shorter paracortical cells inside the curve and longer orthocortical cells outside.

This study examined hair curvature in Japanese women, finding that 47% have curved hair, and identified structural differences in hair fiber, which resemble those in wool fibers.

Only two of the four keratin genes are expressed in wool fibers.

This study observed that hair fibers in older women become more curved with age, decreasing hair luster due to their disordered alignment and structural differences between the convex and concave sides.

This study found that 53% of Japanese women have straight hair while 47% have varying degrees of curved hair, with distinct structural differences observed in the internal makeup of curved hair fibers.

This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.

This paper reviews the complex anatomy and development of human hair and emphasizes the need to understand these processes for interpreting drug incorporation into hair, with no new clinical results reported.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This study introduces a modular fiber model to investigate how changes in microstructural properties of wool affect its critical buckling load, highlighting potential uses and areas needing further research in wool fiber biophysics.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This study focused on the ultrastructural and immunohistochemical aspects of dermal mast cells in systemic mastocytosis and their interaction with the epidermal melanin unit.

This article reviews the potential advantages of secretome derivatives from human uterine cervical stem cells in MSC therapy and notes the need for regulatory standards to ensure safety and efficacy.

This review explores how preconditioning mesenchymal stromal cells can impact their secretome's therapeutic potential in regenerative medicine, emphasizing immunomodulatory and regenerative functions, but provides no new clinical results.

This review discusses the role of TGF-β signaling in stem cell recruitment and tissue regeneration, indicating that abnormalities in TGF-β activation contribute to various major diseases and suggesting avenues for therapeutic intervention.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study suggests that canonical BMP signaling, particularly involving Smad1 and Smad5, plays a critical role in hair follicle stem cell regulation and hair morphogenesis, with distinct roles from pSmad8.

This review discusses various methods for obtaining stem cell-derived conditioned media and its applications in disease treatment, finding generally positive results but highlighting the need for standardized production methods.

This study found that despite the persistence of aberrant double-negative T-cells, functional immune-competence was maintained after thymic transplantation in a patient with a rare FOXN1 mutation.

This case study reported that a 51-year-old woman with hirsutism and voice thickening had a Leydig cell tumor detected by PET-CT, which normalized hormone levels and resolved symptoms after surgical removal.

This Ph.D. project aims to evaluate the self-assembling potential of hair keratin extracts and study the cellular response to both crude and purified keratins, highlighting their potential applications from biomedical to water remediation.

This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

This article reviews innovations in hair cosmetics, focusing on esthetic procedures and products in the Indian market, and reports no new experimental findings.
