This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.

The hydrogel helps heal wounds without scars by releasing two drugs gradually.

This study found that low molecular weight collagen peptide from fish may promote hair growth in both human cells and mice by activating the Wnt/β-catenin signaling pathway.

This study found that incorporating PCL-based nanoscaffolds into liver spheroids enhances their viability and liver-specific biofunctionality, suggesting these scaffolds improve the model's potential for preclinical drug screening by increasing sensitivity to acetaminophen toxicity compared to traditional methods.

This study observed that three-dimensional cultures of dermal papilla cells enhanced endothelial cell migration and angiogenesis in vitro, which may improve vascularization in tissue-engineered skin constructs.

A new method improves the isolation of hair follicle cells for better hair growth research.

In this laboratory study, researchers found that human platelet-rich plasma (hPRP) significantly improved the proliferation and hair-inductive capacity of human dermal papilla cells (hDPCs) compared to fetal bovine serum, suggesting hPRP as a potential substitute for FBS in expanding hDPCs for clinical hair regeneration therapies.

This study demonstrated the potential of newly fabricated epithelial cell scaffolds to enhance hair regeneration, showing promise for future alopecia treatments.

This study identified a subpopulation of neural crest-derived progenitor cells in human corneal endothelial tissue from normal and Fuchs endothelial corneal dystrophy donors, which may have potential for future cell therapy development.

This review discusses human hair follicle development and highlights the potential of creating human in vitro models and skin substitutes with hair follicles, reporting no new clinical results.

This paper discusses how NADPH oxidase and phospholipase D are important for root hair growth, with reactive oxygen species from NADPH oxidase activating calcium ion channels in root hairs.

This study investigated the role of autophagy in human dermal papilla cells and found that inhibiting autophagy accelerates the catagen phase by reducing Wnt/β-catenin signaling. Furthermore, adding ginsenoside Re appears to restore autophagy, suggesting potential benefits for mitigating hair loss linked to autophagy inhibition.

This study demonstrates that Wnt signaling plays a crucial mechanoregulatory role in skin regeneration by influencing cellular responses to substrate rigidity, which promotes hair follicle regeneration in the wound-induced hair neogenesis model.

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.

This study found that washing hair with surfactants reduces the internal density of hair due to cuticle lifting, and suggests that a cuticle-sealing strategy can inhibit this effect and maintain hair homeostasis.

In this study, the authors reported that combining PMSC-secretome and Wnt10b in a GelMA hydrogel scaffold promoted effective hair follicle biofabrication and hair growth in a small in vivo experiment. They emphasized the need for larger studies to confirm these results.

Hair follicle stem cells can become heart muscle cells.

This study used porcine models to isolate and culture stem cells from brain and hair follicles, shedding light on differentiation processes and potential markers for stem cell compartments under lab conditions.

In this study, researchers used 3D bioprinting to successfully create engineered skin tissues with hair follicle-like structures, potentially enhancing skin grafts and safety testing for chemical compounds by more closely mimicking natural skin complexity.

This review discusses the biology and signaling mechanisms of dermal papilla cells in hair follicle growth and reports no new clinical results; the authors emphasize the importance of optimizing culture conditions for hair restoration.

In this study, researchers used a new method with platelet-rich plasma-loaded microcarriers to enhance dermal papilla cell activity and hair follicle regeneration, achieving significant hair and vessel growth in a mouse model compared to control groups.

In this study, researchers successfully derived skin organoids from mouse pluripotent stem cells that spontaneously produce hair follicles, potentially aiding in hair growth research and in vitro drug testing.

In this study, the researchers found that their conductive bio-harvesting tonic enhanced hair follicle proliferation and delayed regression with electric stimulation and the antifungal agent 6-pentyl-α-pyrone in both mice and human hair follicle tests.

This study found that a 3D Matrigel culture technique for dermal papilla cell spheroids can enhance hair follicle inductivity and induce hair-like fiber differentiation in vitro, even with high-passage cells.

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 minireview discusses a proposed model of the vitamin D receptor that explains how 1alpha,25(OH)2D3 can mediate both genomic and rapid responses through different ligand shapes and cellular locations, without presenting new research findings.

This study developed a 3D engineered hair follicle model that mimics the native hair bulb and may aid in drug screening for hair growth therapies.

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 the human placenta extracellular matrix hydrogel restored the hair-inductive capacity of high-passaged dermal papilla cells, enabling them to regenerate new hair follicles when co-grafted with mouse epidermal cells.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.
