This study found that dermal papillae in alopecia areata, including clinically normal follicles, exhibited ultrastructural abnormalities that suggest an early pathological role in the disease's development.

This study explored the epigenetic mechanisms of dermal fibroblast progenitor differentiation and found that the repressive chromatin profile from H3K27me3 prevents these progenitors from reforming skin in allograft assays, despite their multipotent potential.

This study found that Acanthus ebracteatus extract and verbascoside induced dermal papilla cell proliferation and reduced inflammatory cytokine release in vitro, suggesting potential for anti-hair loss applications.

This study found that porcine platelet-rich plasma can be a commercially viable replacement for fetal bovine serum with similar effectiveness in promoting human hair follicle cell growth.

This study found that glucose metabolism supports hair inductive gene expression and hair shaft elongation in dermal papilla cells, suggesting potential applications for in vitro hair follicle generation.

In this study, norgalanthamine was found to stimulate hair growth in cultured rat dermal papilla cells by activating the ERK 1/2, PI3K/AKT, and Wnt/β-catenin signaling pathways.

This study successfully optimized a culture strategy for dermal papilla cells and established an immortalized cell strain, iDP6, which is suitable for research and application.

This study reports that the compound CS-891 can inhibit 5alpha-reductase activity in the dermal papillae of human hair follicles, suggesting potential for treating androgenetic alopecia.

This study identified transcription elongation as a crucial regulatory factor in adipocyte cell fate, showing that the elongation factors Spt4 and Spt6 are essential for proper adipogenic differentiation by aiding RNA polymerase II progression through key adipogenic genes.

In this study using mouse models, researchers found that stress-related hair loss may occur due to CRH-induced PTEN loss and inhibition of autophagy via the PI3K/AKT/mTOR pathway in dermal papilla cells, suggesting potential treatments through PTEN activation or autophagy enhancement.

This study found that encapsulating dermal papilla spheroids in alginate hydrogel with extracellular matrix proteins increased alkaline phosphatase activity, suggesting an enhanced manipulation of dermal papilla activity.

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.

In this study, researchers found that exosomes derived from dermal sheath cup cells (Exo DSCCs) improved proliferation, viability, and migration while reducing apoptosis in senescent dermal papilla cells, also enhancing hair follicle reconstruction and suggesting a potential strategy for combating senile alopecia.

This study describes a novel method using force-triggered density gradient sedimentation for efficiently isolating dermal papilla cells from neonatal mouse skin, showing promise for hair follicle regeneration research.

This study identified the dermal sheath as a driver of hair follicle regression through muscle contraction, essential for reuniting niches and stem cells to regenerate tissue structure during homeostasis.

A substance called FGF9 from certain immune cells can trigger new hair growth during wound healing in mice, but humans may not have the same response due to fewer of these cells.

This review discusses various strategies to enhance drug delivery through the skin barrier, highlighting liposomes as promising carriers for increased dermal concentrations in topical therapies, but reports no new research results.

This study suggests that epigallocatechin gallate (EGCG) from green tea may counteract DHT-induced hair follicle damage by modifying the miRNA expression profile in human dermal papilla cells.

This study diagnosed a group of six girls with various ectodermal abnormalities, identifying cranio-skeletal malformations consistent with focal dermal hypoplasia (Goltz syndrome), and found heterozygous mutations in the PORCN gene in two children.

This study found that intradermal injections of cultured autologous dermal sheath cup cells for androgenetic alopecia showed hair loss stabilization at 24 months without serious adverse effects and a sustained response in some participants.

This study found that acute stress in rats inhibits hair growth, likely through increased cortisol levels and activation of the substance P-mast cell pathway.

In this study, researchers accomplished the total synthesis of calanthoside, noted for its strong proliferative effects on human hair follicle dermal papilla cells, using a seven-step process from anthranilic acid with a 43% overall yield.

This study demonstrated in rodent models that artificial dermal template treatment can induce full-thickness skin regrowth including skin epidermis and adnexa without the need for autologous skin grafts.

This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study found that papillary dermal fibroblast progenitors in newborn mouse skin can be isolated and cultured to generate male germline cell precursors, demonstrating their potential through differentiation into cells with meiotic capability.

In this study, exosomes derived from Iris germanica L. rhizomes (Iris-exosomes) were reported to alleviate oxidative stress and improve mitochondrial function in human follicle dermal papilla cells by activating the Wnt/β-catenin signaling pathway, suggesting potential benefits for hair loss treatment.

This study found that dermal papilla cell-derived exosomes promote hair follicle regeneration during wound healing by enhancing fibroblast activity and activating the Wnt/β-catenin signaling pathway in mice.
