This study developed a method to culture and maintain chicken feather follicles in vitro, preserving structure and biology similar to their in vivo state, though some gene expression was altered.

A new method was developed to create better skin models for healing and reconstruction.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

This study observed that Trps1 gene expression in mice is precisely regulated in skin development, particularly during hair follicle morphogenesis, with distinct localization patterns in different cell types.

This study suggests that fibroblast growth factors exhibit significant expression differences in rodent and primate skin, potentially related to their evolutionary paths and environmental adaptations.

This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

This study found that the transcription factor Trps1 acts as a novel regulator of the Wnt signaling pathway and early hair follicle progenitors in developing vibrissa follicles in mice.

In this study, researchers identified elongated corkscrew hairs as a new trichoscopic pattern in immunosuppressed adults with chronic endothrix tinea capitis, which may help in earlier diagnosis and targeted mycological investigation.

This study used transcriptome analysis to explore the genetic mechanisms behind the development and seasonal variation of nuptial pads in R. chensinensis, identifying key genes and processes that suggest the pads' development involves complex regulatory pathways, particularly those related to cell cycle and hormone synthesis.

Hair malformations may occur due to timing issues in hair development.

This study found no structural differences between in vitro and in vivo grown hair, with keratinization and organization of keratin being comparable in both settings.

This study showed that a 2-kilobase upstream region of the mouse keratin 17 gene enables targeted GFP expression in major epithelial appendages of transgenic mice, indicating sonic hedgehog's involvement in its regulation.

This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.

In this study, the degradation of HHK scaffold particles was linked to the activation and proliferation of satellite cells, which may contribute to new muscle fiber formation.

This study suggests that large corneal stem cells isolated from the stratum corneum may be capable of covering central wound areas when transplanted onto granulation tissue.

In this study, transgenic mice expressing Msx-2 developed flaky skin with hyperproliferation and misalignment in epidermal cells, suggesting Msx-2 plays a role in skin and appendage growth control.

In this study, researchers mapped gene expression in developing hair follicles to reveal unknown cell populations and markers, suggesting early establishment of cell fates in hair placodes.
