At the 21st Royan International Stem Cell Congress, researchers highlighted the growing integration in regenerative medicine, emphasizing advances in pluripotency, AI applications, and bioengineering for the development of accessible stem cell therapies.

In this review, researchers examined how needle gauge and length impact the viability of human stem cells during injections, emphasizing the balance between minimizing tissue trauma and preserving cell viability to optimize clinical protocols.

This clinical trial found that using a 45-degree angled implanter with the bevel facing the skin in FUE hair transplantation significantly reduced insertion resistance, graft popping, and bleeding, while improving efficiency and graft alignment compared to conventional methods.

This study introduces PROMETHEUS, a framework that organizes causal claims from scientific texts into navigable and persistent "causal atlases," enhancing research by highlighting localized evidence, agreement, and contradictions within complex data sets.

This study found that human skin melanocytes with low mutation burdens are smaller, less dendritic, and exhibit stem-like features, often residing in UV-protected hair follicles, suggesting their role in replenishing sun-damaged epidermis.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

In a conditional knockout mouse model, this study found that loss of the transcription elongation factor SPT6 in basal keratinocytes led to psoriasis-like skin inflammation and delayed wound healing, suggesting SPT6 plays a crucial role in maintaining epidermal immune quiescence by suppressing proinflammatory NF-κB signaling.

This study demonstrates that a novel autologous hair follicle-derived epithelial sheet can effectively repigment skin in patients with stable vitiligo, offering a potential new treatment option.

This review presents a comprehensive evaluation of medical reasoning using large language models, highlighting a significant gap between exam-level performance and true clinical decision-making accuracy.

This study constructed a single-cell atlas of hair follicle cells from yaks and taurine cattle, revealing that differences in WNT signaling within dermal papilla cells may be key to the yak's adaptation to cold environments on the Qinghai-Tibet Plateau.

In this study, researchers explored drug repurposing as a potential strategy for treating psoriasis and identified Pioglitazone, Trimipramine, and Dimetindene as promising candidates for this indication, based on molecular docking and predictive algorithms.

This study found that human placental extract significantly improved melasma, chronic ulcers, and alopecia areata without major adverse effects, suggesting its effectiveness and safety for these conditions.

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 constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study concluded that high-intensity interval training (HIIT) offers superior benefits over standard moderate-intensity continuous training (MICT) in improving aerobic capacity, insulin sensitivity, hormonal profiles, and anxiety scores in overweight women with PCOS.

The study found that dermal EZH2 plays a crucial role in coordinating dermal fibroblast differentiation and epidermal development by modulating Wnt/β-catenin and retinoic acid signaling.

This study found that the Polycomb Repressive Complex 2, particularly its component Ezh2, is crucial in regulating dermal fibroblast differentiation and epidermal keratinocyte proliferation during murine skin development.

This abstract suggests that cost barriers limit the application of standard aesthetic procedures in developing countries, while exploring platelet-rich plasma as a potentially safer and less invasive option in geriatric aesthetics. Detailed results were not reported.

This article introduces geriatric aesthetics and discusses the potential of platelet-rich plasma as a cost-effective solution in developing countries, but reports no new clinical results.

This dissertation reported that the loss of Ovol2 impairs hair follicle regeneration and wound repair in mice, highlighting its role in regulating directional migration of epithelial cells.

In this study, a very low-calorie ketogenic diet significantly improved metabolic and hormonal profiles in obese men, but did not significantly enhance most semen parameters except for sperm motility.

This study concludes that one year after COVID-19 infection, patients in Northeast Brazil showed improvements in quality of life, although some symptoms such as anxiety and memory loss persisted.

This study developed a multifunctional bilayer dressing containing nanosilver and basic fibroblast growth factor, which improved wound healing by preventing bacterial penetration, promoting angiogenesis and hemostasis, and accelerating cell proliferation and migration, outperforming a control group by increasing healing rates by 47% in vivo.

This integrative review developed a Spiral Model to better represent human hair follicle dynamics and aging, which may assist in distinguishing natural aging from pathological changes and improving trichological interventions.

This review discusses the current understanding of polycystic ovary syndrome, focusing on its epidemiology, pathophysiology, diagnosis, management, and future research directions, but reports no new clinical results.

This paper reviews the diagnostic criteria, etiological factors, and treatment approaches for PCOS, highlighting the importance of considering metabolic issues such as insulin resistance and obesity, but reports no new findings.

This review examines the role of nerves in regeneration across various species and discusses their importance as components in the progenitor cell niche, reporting no new clinical results.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

This literature study reviews the consequences of hair loss due to chemotherapy and nursing care interventions but reports no new clinical results.

This review discusses recent findings on the plasticity and regulation of epithelial stem cells and reports no new experimental results.
