This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

In this study, mannosylerythritol lipids from soybean oil notably increased fibroblast and papilla cell viability, suggesting potential as a hair growth agent.

This study found that hair follicle cells' growth in vitro is influenced by the concentration of androgens and antiandrogens, with papilla cells and outer root sheath keratinocytes showing distinct sensitivity.

The researchers reported that marine-derived saccharides, specifically L-fucose and chondroitin sulphate disaccharide, supported skin and hair health by promoting cellular proliferation, enhancing extracellular matrix production, and aiding the hair cycle's growth phase, potentially minimizing aging effects.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This article provides contact information for Bruce A. Morgan and features no new research findings.

This study found that treatment with mesenchymal stem cell extracellular vesicles enhanced hair growth in mice and stimulated dermal papilla cell activity and growth factor production in vitro.

This study found that cultured human dermal papilla cells formed into three-dimensional spheres have an increased ability to induce hair follicles from mouse epidermal cells compared to two-dimensional cultures.

This study found that composite skin constructs containing dermal papilla cells promoted better skin healing and hair regeneration in nude mice, highlighting their role in tissue-engineered skin for severe injuries.

This study reported that a three-dimensional hydrogel culture system supports the growth and maintenance of distinct dermal papilla cell types, crucial for skin reconstitution assays in neonatal mice.

This study developed a method for expanding human dermal papilla cells in vitro while maintaining their ability to induce hair growth, advancing the potential for follicular cell implantation as a treatment for hair loss.

This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

This research observed that dermal papilla cells have the potential to regenerate hair bulbs under preferred environmental conditions when associated with dermal sheath cells or exposed to specific growth factors.

This study demonstrated that cultured human dermal papilla cells can induce full hair follicle formation when combined with neonatal foreskin keratinocytes in a grafted dermal-epidermal construct on mice.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

This study found that dermal papilla cells from beard and axillary hair follicles can produce androgen-dependent factors that stimulate proliferation in adjacent follicular epithelial cells under testosterone influence.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This study developed a 3D engineered hair follicle model that mimics the native hair bulb and may aid in drug screening for hair growth therapies.

This study shows that the concentration of epidermal growth factor (EGF) is crucial for determining whether mink hair follicles are promoted or inhibited in vitro, with involvement of the Notch signaling pathway in DP cell proliferation.
