In this study, knockdown of XIST in 3D-cultured dermal papilla cells inhibited hair follicle regeneration by interfering with miR-424 and hedgehog signaling, highlighting XIST's role in hair development.

This article reviews how aging affects skin and stem cells, but it contains no new research findings.

This study found that the interaction between heat shock protein 90 and lamin A/C is crucial for the growth, migration, and self-aggregation of dermal papilla cells, suggesting a potential role in alopecia areata mechanisms.

This study found that topical administration of the TGFβ mimetic peptide DPS-1 stimulated hair growth in mice by promoting HDP cell proliferation and enhancing hair follicle morphology.

This study found that taxol induces apoptosis in dermal papilla cells, affecting protein expression related to biological processes and potentially contributing to taxol-induced alopecia.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

In this study, researchers developed a new 3D skin equivalent assay using mouse epidermal and dermal cells that successfully regenerated organized hair follicles, outperforming a 2D model in hair follicle orientation and quantity, and enhanced hair growth when Wnt3a was added.

In this study, researchers developed a chemical cocktail and suspension culture method to transform human dermal fibroblasts into dermal papilla-like cells capable of inducing hair follicle formation in vitro and in vivo.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study found that silk fibroin/sodium alginate scaffolds seeded with dermal papilla cells may accelerate skin repair and hair follicle regeneration in a rat model.

This study found that androgens downregulate BMP2 in dermal papilla cells, inhibiting hair follicle stem cell differentiation, while BMP2 addition may restore hair lineage differentiation through the Wnt/β-catenin pathway.

This study identified ten key hub genes and pathways crucial for understanding the molecular mechanism of hair growth by comparing dermal papilla cells in 2D and 3D cultures.

This study found that treating a 3D hair dermal papilla model with rice bran extract and electromagnetic fields increased melanogenesis, suggesting potential for vitiligo and white hair therapies.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

This study found that a specific fragment of AIMP1, secreted by hair follicle stem cells, activated dermal papilla cells, leading to enhanced hair regrowth and maintenance in mice.

Using a combination of specific cell cycle regulators is better for safely keeping hair root cells alive indefinitely compared to cancer-related methods.

In this study, extracts from three Polynesian plants—Bidens pilosa, Calophyllum inophyllum, and Fagraea berteroana—were found to increase dermal papilla cell proliferation and modulate hair growth-related gene expression, suggesting potential for stimulating hair growth.

This study found that all-trans retinoic acid (ATRA) negatively affects hair growth by reducing goat dermal papilla cell viability and growth factor expression.

In this study, injectable platelet-rich fibrin (i-PRF) was found to enhance the proliferative, migratory, and hair-inducing abilities of dermal papilla cells more effectively than platelet-rich plasma through the TGF-β/Smad pathway.

This study developed a new human hair research model combining 3D spheroid dermal papilla fibroblasts with plucked anagen hair shafts, potentially improving the evaluation of hair follicle differentiation.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.

This study found that CARI ONE, a herbal mixture, promotes hair growth in mice by inducing the transition from telogen to anagen phase and enhancing hair follicle development, compared to control and minoxidil treatments.

This study found that mesenchymal cells in mouse and chicken embryonic skin undergo a process of migration driven by tissue tension and WNT secretion, influencing their dispersal and integration into dermal condensates.
