Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This review highlights that disturbances in neuroimmune communication, particularly between sympathetic nerves and macrophages, may contribute to autoimmune diseases like rheumatoid arthritis and type 1 diabetes, and suggests potential therapeutic avenues by restoring this communication in preclinical and early clinical studies.

This study suggests that platelet-rich plasma's high levels of growth factors may be limited in promoting bone regeneration due to the concurrent release of Dickkopf-1, which inhibits osteogenesis.

In this study, type I interferon response-related genes activated by RIG-1 and IL-17 signaling pathways were significantly up-regulated in both hair follicles and skin tissues affected by chronic discoidal lupus erythematosus.

This study found that type I interferon response-related genes activated by RIG-1 and IL-17 pathways were significantly up-regulated in hair follicle and skin samples with chronic discoidal lupus erythematosus.

This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.

Certain micronutrients may improve hair and nail health, but more research is needed to confirm their benefits.

This study found that deslorelin implants can effectively reduce estradiol levels and support hair regrowth in neutered ferrets with hyperoestrogenism caused by nodular hyperplasia of the adrenocortex.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

This study found that fibromodulin significantly reduces scar formation and boosts scar strength in rodent and porcine models, suggesting potential for FMOD-based therapies in cutaneous wound repair.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This study found that the E2-ANGPT2 pathway is involved in hair follicle regulation and that ANGPT2 treatment increased hair density in modeled female pattern hair loss, suggesting potential therapeutic use.

This study developed a composite hydrogel that delivered multiple proteins, enhancing skin wound healing by accelerating closure and promoting hair follicle regeneration.

This study identified genes potentially involved in hair and cashmere growth in the Laiwu black goat, highlighting specific gene expression differences between hair-growing and hairless skin.

In this study, researchers developed a new method called Enriched-GF, which enhances growth factor recovery from platelet concentrates through a combination of glass bead activation, freeze-thaw cycling, and calcium stimulation, outperforming conventional methods by providing higher and more consistent yields for regenerative medicine applications.

This study found that mature adipocytes can dedifferentiate into fibroblast-like cells, driven by PDGF and TGFβ signaling, which may play a role in wound repair and fibrosis.

This narrative review explores the potential influence of brown adipose tissue on polycystic ovary syndrome and reports no new experimental findings.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

This study found that keratinocytes show increased expression of the TGF-β system and collagen type I with age, suggesting a heightened profibrotic response during skin differentiation associated with scarring.

This study suggests that in gilthead seabream, DHT is involved in the onset of the meiotic phase of spermatogenesis and influences serum levels of E2 through regulation of aromatase activity.

This study found that glucose starvation and hypoxia are physiological triggers of ER stress in in vitro differentiated adipocytes, rather than high concentrations of saturated fatty acids, cholesterol, or proinflammatory cytokines.

This study found that dexamethasone significantly reduced ERα mRNA levels and increased aromatase mRNA and activity in cultured human hair follicle dermal papilla cells, suggesting a glucocorticoid-dependent mechanism for estradiol action.

This study reviews evidence that in keloid development, transforming growth factor-β (TGF-β) drives fibroblast proliferation and fibrosis not only through the classical Smad-dependent pathway but also via equally important Smad-independent signaling cascades, suggesting these pathways as possible targets for more effective keloid therapies.

This review summarizes current evidence on how beta-human papillomavirus and Merkel cell polyomavirus may contribute to the development of nonmelanoma and Merkel cell skin carcinomas, respectively, but it reports no new clinical findings.

This review discusses the roles and therapeutic effects of GLP-1 receptor agonists on the nervous, cardiovascular, and endocrine systems, but reports no new clinical results, emphasizing the need for further research on their impact on metabolism and tumor relationships in type 2 diabetes patients.

This study found that thymosin beta-4 overexpression in mice increased hair growth speed and density, likely by regulating P38/ERK/AKT signaling through VEGF expression.

This review suggests systemic changes in polycystic ovary syndrome may increase the risk of neurodegeneration, potentially linking it to Alzheimer's disease through common pathways affecting tryptophan metabolism.

This study suggests that BTP levels in cerebrospinal fluid might help diagnose CIDP and predict therapy response but require validation in larger cohorts.

This study found that EP 2 signaling is crucial for macrophage recruitment and inflammatory regulation in the injured heart, impacting cardiac repair processes.
