This study reported that canine dermal papilla cells showed a distinct growth pattern and strong collagen IV and laminin staining compared to dermal fibroblasts.

This study found that canine dermal papilla cells and fibroblasts metabolize androgens differently than human hair follicle cells, indicating species-specific differences in androgen metabolism.

This article discusses the role of dermal papilla and dermal sheath cells in the hair cycle and reviews finasteride and minoxidil's mechanisms in promoting hair growth, but presents no new clinical findings.

In this study, fibroblasts treated with the small molecule peficitinib were reprogrammed into dermal papilla cell-like cells capable of inducing hair growth, offering a new strategy for hair loss treatment.

This study found that minoxidil significantly increases VEGF mRNA and protein expression in dermal papilla cells, suggesting a role in enhancing hair follicle vascularization in androgenetic alopecia.

In this study, VD(3) pretreatment increased hair follicle formation in a rat model by promoting dermal papilla cell differentiation, suggesting potential for hair regeneration therapy.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study found that hypoxia increases the proliferation of dermal papilla cells and highlighted the important role of lactate dehydrogenase in this process.

This study found that dihydrotestosterone (DHT) may shorten the hair growth cycle through mechanisms like cell-cycle arrest and β-catenin downregulation in rat hair follicle cells.

This study found that mycophenolic acid promotes dermal papilla cell proliferation and anagen hair follicle induction in mice, suggesting potential as a treatment for hair-loss disorders.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study suggests that interleukin-1 α influences dermal papilla cell activity by modifying androgen receptor expression and increasing the secretion of several growth factors and cytokines.

This study found that the humanin analogue HNG significantly promoted hair growth in vitro and in vivo by prolonging the anagen phase and inhibiting hair follicle cell apoptosis in mice.

This study found that Cacumen Platycladi volatile oil promotes dermal papilla cell proliferation and enhances hair growth in mice, outperforming minoxidil and showing no obvious cytotoxic effects.

In this study, dermal fibroblasts in the head of beagle dogs metabolized the highest amount of progesterone, primarily into cortisol, while dermal papilla cells mainly produced 5α-pregnane-3,20-dione and cortisol.

This study found that EGR1 promotes the proliferation of dermal papilla cells, suggesting its close association with hair follicle growth and development.

This study found that the lncRNA lncRNA2919 is involved in hair follicle regeneration by downregulating growth-related genes, inhibiting cell proliferation, and promoting apoptosis in rabbit dermal papilla cells.

In this study, Allium hookeri extract increased viability and size of dermal papilla cell spheroids and reduced oxidative stress effects, potentially promoting hair growth by regulating specific protein signaling pathways in human cells.

This study found that transplanting trichogenous dermal cells significantly enhanced the restoration of in vivo-damaged hair follicles in a nude rat model, with a combination of dermal papilla and sheath cells proving more effective than either cell type alone.
