This study found that new methods for isolating human dermal papilla cells were more efficient than traditional methods, maintaining higher levels of specific markers and improving the cells' research potential.

This study found that higher concentrations of topical diphenylcyclopropenone, especially when prepared with acetone, showed better stability over 6 months compared to lower concentrations.

This study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This study found that prostaglandin D2 promotes androgen receptor and AKT signaling in human dermal papilla cells through the DP2 receptor, potentially contributing to androgenetic alopecia.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

This review discusses the potential of polydeoxyribonucleotide (PDRN) for various dermatological treatments and highlights its significant effects on wound healing, anti-aging, acne scars, and hair loss, but emphasizes the need for further clinical studies.

In this study, researchers found that overexpression of CRABP2 enhanced the proliferation of dermal papilla cells in Hu sheep through activation of the Wnt/β-catenin pathway, even when the pathway was inhibited.

This study found that p2y5 functions as a novel LPA receptor involved in the G13-Rho signaling pathway, with implications for human hair growth, and proposes renaming it to LPA6.

This study found that Polycomb repressive complex 1 is crucial for skin development and stem cell specification, influencing gene activity beyond its known repressor functions.

This study showed that treating mouse fibroblasts with TTNPB can efficiently convert them into dermal-papilla-cell-like cells with strong hair-inducing capacity, suggesting potential for hair follicle regeneration therapies.

This review analyzes PDRN's molecular mechanisms and therapeutic applications in anti-aging dermatology but reports no new clinical results, highlighting the need for more standardized protocols and long-term evaluations.

This study found that topical diphenylcyclopropenone is an effective treatment for extensive alopecia areata, with significant hair regrowth reported in most patients, though effectiveness varied with disease characteristics.

This study found that PDCD4 protein expression is reduced in various skin cancers compared to normal skin, suggesting its potential role in preventing or treating certain skin cancers.

This study found that actively targeted AN2728-loaded nanocarriers reduced inflammation and improved skin condition in a mouse model of psoriasiform inflammation compared to free drug and non-targeted nanoparticles.

ATP-sensitive potassium channels are important for hair growth.

This study found that treatment with diphenylcyclopropenone led to more than 75% hair regrowth in 33.3% of patients with alopecia totalis or alopecia universalis, despite notable side effects.

PP405 may help hair growth by activating hair follicle stem cells.

This study found that ovine dermal papilla cells exhibit robust aggregation and alkaline phosphatase activity, regulated by Wnt/β-catenin signaling, providing insights for improving wool performance and hair regeneration therapies.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This study reviewed existing articles to assess the efficacy of topical diphenylcyclopropenone immunotherapy for alopecia areata, but it did not report new clinical results.

This study suggests that higher PDCD4 expression may play a significant role in polycystic ovary syndrome pathogenesis through its association with obesity, insulin resistance, lipid metabolism disorders, and increased granulosa cell apoptosis.

This letter discusses three plasmacytoid dendritic cell-related parameters that may help differentiate lupus alopecia from lichen planopilaris, but it reports no new study results.
