This study revealed that telocytes are crucial Wnt-producing niche cells necessary for hair follicle regeneration in mice, with their removal or the absence of their Wnt signals halting the regenerative process.

This review discusses using cultured dermal papilla cells to investigate hair follicle biology, emphasizing their potential to inform treatments, but reports no new clinical results.

This study found that dermal white adipose tissue surrounding human hair follicles enhances proliferation, pigmentation, and hair shaft elongation in an ex vivo setting.

This study suggests that PKCß plays a critical role in modulating the dermal inflammatory microenvironment in response to dietary lipids in mice.

Dermagraft and Dermalogen had a lot of granulation, while Alloderm, Integra, and ADM had good blood vessel growth for skin healing.

This study found that telocytes are present in the human dermis, suggesting a potential role in skin homeostasis, remodeling, regeneration, and repair.

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.

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.

This study found that androgen metabolism within hair follicles varies significantly between compartments, with dermal papillae showing high 5α-reductase activity, suggesting a key role in androgen-driven hair growth responses.

This study found that 3D cultured hair follicle-like constructs, which include keratinocytes and dermal papilla cells, showed improved gene expression and cell interactions relevant to hair follicle development.

This study demonstrated that the large molecule versican plays a critical role in hair induction in dermal papilla cells, with potential implications for developing new hair growth treatments.

This study found that inhibiting 11β-HSD1 can partially reverse the negative impact of glucocorticoids on dermal papilla cells in human scalps, suggesting potential for treating stress-related hair loss.

This study observed that human primary adult hair matrix keratinocytes may have the potential to generate hair follicle organoids, suggesting possible applications in hair follicle neogenesis and preclinical hair growth agent screening.

This study found that co-culturing dermal papilla cells in a 3D structure with adipose-derived stem cells may enhance the expression of hair inductivity markers compared to 2D cultures.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

In this review, researchers summarize the methods for characterizing telocytes, outline their physiological roles and implications in diseases, and discuss potential future studies including precise markers and targeted therapies.

This case report suggests that human dermal papillae conditioned media may accelerate wound healing in congenital aplasia cutis due to varicella infection.

This study found that epigallocatechin-3-gallate (EGCG) may reduce paclitaxel-induced apoptosis in human dermal papilla cells by regulating microRNA expression related to apoptosis and cell proliferation.

This study reports that extracellular microvesicles isolated from stimulated dermal fibroblasts enhanced hair follicle growth ex vivo and identified norrin as a novel modulator in hair regeneration processes.

This study reports that in systemic sclerosis, CD34+ dermal fibroblasts transition to CD34−, podoplanin+, and CD90+ fibroblasts across the dermis, suggesting a role in unchecked fibrosis.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This study defines classification criteria for hair follicle dystrophy using a mouse model of chemotherapy-induced alopecia, providing tools for standardized hair damage assessment.

PRP may help with hair loss and improve hair quality with few side effects, but more research is needed.

This study suggests that macrophages play a more substantial role in the pathogenesis of Lichen planopilaris compared to Frontal fibrosing alopecia, as indicated by increased CD68+ cells in Lichen planopilaris.

This study found that the cell of origin in mouse skin affects melanoma phenotype and response to therapies, despite the presence of the same genetic mutations.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This study found that canine hair follicle stem cells are located in the isthmus/bulge region of the hair follicle, surrounded by telocytes.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.
