This study found that conditioned medium from keratinocytes improved the hair-inductive properties of cultured dermal papilla cells, suggesting potential for enhancing hair follicle regeneration.

In this study, researchers found that the interaction between dermal papilla and endothelial cells decreases with age, affecting signaling pathways that promote hair regeneration and angiogenesis in mouse models.

This study found that microporous electrospun scaffolds with a 70:30 collagen I to poly(ɛ-caprolactone) ratio significantly accelerated wound closure and dermal regeneration in full-thickness critical-sized skin defects.

This study found that hydrogels supplemented with fractionated platelet-rich plasma recruited more dermal-derived stem cells and accelerated healing, leading to hair growth and skin regeneration in rats.

This study describes how manipulating the actin cytoskeleton, particularly through the gelsolin family proteins, may enhance regenerative healing in mammals, suggesting potential therapeutic pathways for improved wound repair.

In this mouse study, researchers reported that sequential monopolar-bipolar radiofrequency irradiation significantly improved skin quality by increasing collagen density, elastin fiber expression, and fibroblast differentiation more than monopolar RF treatment alone.

This study observed that in mouse fetuses, reticular contraction by actomyosin is involved in dermal regeneration, and differences in actin and α-SMA localization may determine the switch between regeneration and scar formation, suggesting potential insights for wound regeneration therapy.

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 identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

This study found that engineered reconstituted skin can form morphogenetic units that promote tissue patterning and hair regeneration, with certain signaling pathways restoring this ability in adult and fetal cells.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This study found that both human and rat dermal papilla spheroids can induce hair follicle neogenesis, but larger spheroids increase inductivity without significantly affecting hair fiber diameter.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

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 demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This study found that photobiomodulation enhanced hair regeneration in injured dermis of mice, likely through increased migration and exosome secretion of dermal papilla cells via the Akt/GSK-3β/β-catenin pathway.

This study suggests that human dermal fibroblasts can be converted into dermal papilla cell-like cells using microencapsulation, which may facilitate hair follicle regeneration in mice without chemical or genetic reprogramming.

This study found that transplanting genetically modified dermal fibroblasts into full-thickness skin defects in rats led to the formation of hair follicles with mature pilosebaceous systems by 16 weeks.

Certain cells around hair follicles help improve skin regeneration for potential use in skin grafts.

This study found that Shi-Bi-Man, a hair health supplement, significantly promoted hair growth in mice, likely through activation of the FGF signaling pathway.

This paper proposes that GDNF signaling may enhance skin regeneration and hair follicle formation by influencing dermal fibroblast differentiation, particularly following injury.

This study found that JUNB enhances hair regeneration in mice by promoting dermal papilla cell proliferation through the Wnt signaling pathway, suggesting JUNB as a potential molecular target for improving cashmere quality and breeding in cashmere goats.

This research reported that STAT5 activation in the dermal papilla plays a crucial role in triggering anagen entry during post-developmental hair follicle cycling.

Chitosan-coated nanocapsules improve minoxidil delivery for better hair regrowth.

JW0061 may be a new treatment for hair loss by promoting hair growth through WNT signaling.

In this study, human dermal fibroblast-conditioned medium was found to contain numerous proteins involved in wound repair and hair regeneration, with identified proteins forming interaction networks linked to key signaling pathways like epidermal growth factor receptor and transforming growth factor-β.

This study suggests that early-stage dermal papilla cell-derived exosomes may enhance adipose stem cells' hair inductive abilities through specific miRNAs.

This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.
