This study found that upper wound fibroblasts are crucial for hair follicle regeneration during wound healing and suggests that these cells, along with papillary fibroblasts, migrate within the wound.

This chapter reviews the potential role of gonadal hormones in sex differences in play and spatial behavior, noting a lack of conclusive evidence but suggesting perinatal androgen exposure might contribute to observed differences. It reports no new research results.

Dark skin has stronger barriers and structure due to specific gene activity.

In this study, researchers found that Dlx3 plays a crucial role in regulating chromatin accessibility and gene transcription during keratinocyte differentiation in the epidermis, highlighting its potential impact on epidermal barrier formation and differentiation.

This review highlights recent research using single-cell RNA sequencing and machine learning in wound healing, revealing significant insights into fibroblast diversity, immune cell dynamics, and the spatial organization of cells, which may transform therapeutic strategies for chronic wounds, fibrosis, and tissue regeneration.

This study discovered a conserved "fiber-like-motif" of melanosomes aligned in hair across various mammalian species, shedding light on the internal structure that influences hair's thermal and mechanical properties.

This study developed an in vitro system to analyze human skin progenitor cells' ability to form hair peg-like structures, providing insights for engineering hair follicle organoids.

This study developed a comprehensive atlas of human scalp tissue to uncover cell states and lineages in hair follicles, identifying disease-specific cellular changes associated with non-scarring and scarring hair loss, which may offer new diagnostic and therapeutic insights.

This study found that epithelial cells in the skin of live mice regulate the density and spatial organization of immune cells, which actively maintain their position despite constant cell turnover.

In this study, researchers used spatial transcriptomics to identify increased expression of genes linked to extracellular matrix organization and epithelial–mesenchymal transition in the progenitor cell regions of hair follicles in androgenetic alopecia patients, suggesting a possible role in progenitor cell loss and fibrogenic microenvironment development.

This study found that carefully engineered hydrogels and asymmetric morphogen gradients facilitated the formation of anatomically relevant skin organoids from iPSC-derived EBs, improving pigmentation and hair follicle generation.

Crickets have genetically controlled hair plates that help them sense and move their antennae.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.
