This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

The researchers observed that in cichlid fishes with different dental structures, tooth replacement accelerated more than three times following tooth extraction, alongside distinct changes in gene expression and cellular interactions over one week, providing insights into tooth regeneration mechanisms in vertebrates.

This study observed that interferon β secreted by dermal papilla cells may negatively regulate the growth of outer root sheath cells in hair follicles.

This review emphasizes the importance of understanding hair follicle embryology, anatomy, and the hair cycle to effectively diagnose and treat hair disorders like alopecia.

This study reports that stress-related neurohormones and factors, such as CRH and SP, can inhibit hair growth and alter immune functions in murine and human hair follicles.

This review discusses key signaling pathways involved in tooth formation, highlighting their role in understanding tooth regeneration and potential therapies for dental abnormalities.

This study found that keratinocytes derived from the germinative epithelium of ovine hair follicles have extensive in vitro growth potential, challenging the idea that these cells are solely transit-amplifying.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

This study found that specialized nipple epidermis in mice is maintained by the repression of TGFβ signaling through estrogen, which highlights the role of hormonal regulation in epidermal maintenance.

This study identified that in mice, sweat gland development is directed by mesenchymal signals that suppress SHH-production, while in humans, this occurs through a BMP spike in embryonic development.

This study introduces a method using lentiviral delivery in mice to expedite analysis of factors crucial for hair follicle morphogenesis by enabling rapid gain- or loss-of-function studies.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.
