It has long been well documented that the microenvironment evolves over time, making it crucial to identify the optimal transplantation window to maximize therapeutic efficacy. However, it remains uncertain whether acute or delayed local cell transplantations better supports graft viability after stroke. Here, it is shown that delayed intracerebral transplantation of neural progenitor cells (NPCs) derived from human induced pluripotent cells (iPSCs) at 7 days post stroke significantly enhances graft proliferation and survival, and promotes axonal sprouting, compared to acute transplantation at 1 day post stroke, in a mouse model of large cortical stroke. Using in vivo bioluminescence imaging over a 6-week period post-transplantation, a more than fivefold increase is observed in bioluminescence signal in mice that received delayed NPC therapy, compared to those that underwent acute NPC transplantation. The increased number of cell grafts in mice receiving delayed NPC transplantation is driven by increased proliferation rates early after transplantation, which subsequently declines to similarly low levels in both groups. Notably, it is found that the majority of transplanted NPCs differentiate into neurons after 6 weeks, with no significant differences in the neuron-to-glia ratio between acute and delayed transplantation groups. These findings suggest that delayed NPC transplantation improves early graft survival and proliferation, which could help identify the optimal therapeutic window for maximizing the effectiveness of NPC-based therapies in stroke.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e04154"},"PeriodicalIF":14.3,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DMSO-free processed tin perovskites are gaining interest due to the detrimental effects of DMSO on tin oxidation. However, replacing DMSO with other solvents remains challenging due to the accelerated crystallization dynamics in non-DMSO systems. In this study, the crystallization process in a DMSO-free solvent system is regulated by managing the transition from the sol-gel phase to the solid film. Specifically, piperazine dihydriodide (PDAI) and 4-tert-butylpyridine (tBP) are utilized to coordinately tune the colloidal chemistry through forming large pre-nucleation clusters in perovskite ink, further, facilitating the film formation process. By combining tBP and PDAI, a controllable crystallization rate is achieved as evidenced by in situ photoluminescence (PL) measurement during spin-coating. As a result, tin perovskite films show high crystallinity and improved microstructure. Devices treated with tBP+PDAI exhibit a champion power conversion efficiency of 7.8% and excellent stability without observable degradation for over 3000 h stored in the N2 glovebox.

Human patients with ulcerative colitis (UC) and Crohn's disease (CD), and mice with three different models of colitis, express a significant decrease in the expression of BD-1 in colonic epithelial cells (CECs). Dietary and environmental AhR ligands induce the expression of BD-1 in CECs through the activation of two dioxin-responsive elements (DREs) expressed on its promoter. AhR ligands attenuate colitis in wild-type (WT) mice while inducing BD-1.

Blocking BD1 in vivo using antibodies prevents the ability of AhR ligands to ameliorate colitis, restore dysbiosis, and attenuate colonic inflammation.

By establishing critical correlations between post-processing thermal protocols and alkali metal migration dynamics, how synchronized extension of sintering duration and rapid cooling termination creates a non-equilibrium state that traps Na at strategic interfacial positions is demonstrated. This approach leverages Na's dual functionality as a crystallization promoter and defect passivator, driving concurrent improvements in crystallographic coherence and electronic uniformity. The optimized absorber architecture features laterally expanded grains with reduced boundary density and homogenized interfacial charge transport pathways, yielding the highest reported efficiency of 13.22% for Na-doped CZTSSe solar cells to date, marked by synergistic enhancements in both VOC and FF. Crucially, this substrate-derived Na regulation paradigm outperforms conventional extrinsic doping methods through its self-limiting diffusion characteristics, ensuring compositional stability while eliminating secondary phase risks. The methodology establishes a universal framework for defect engineering in chalcogenide photovoltaics, bridging fundamental insights into alkali metal diffusion thermodynamics with scalable manufacturing solutions.

To overcome this issue, a pump-free, hydraulic-amplification oscillatory microfluidic (PHOMF) device is presented, which can be actuated by fingers to handle particles and cells within the microchannel. The PHOMF device has a hydraulic-amplification module for pressure transfer and a soft microchannel module for the generation of oscillatory flows. This is made possible by the periodic transfer of finger-driven liquid pressure to the soft microchannel. This pressure causes the soft microchannel to deform and then drives the reciprocating flow of fluid volumes within the microchannel. In the oscillatory flow, particles and cells achieve single-line focusing driven by the spatially accumulated inertial and elastic lift forces. The particle elasto-inertial focusing theory in the PHOMF microchannel has been revealed. To demonstrate the system's practicality, the PHOMF device is utilized to achieve the early observation of platelet clots (3 min) and the rapid staining of cancer cells (8 min). The PHOMF device provides a miniaturized, inexpensive, and efficient detection tool for lab-on-a-chip, and has the potential to become a mass-produced, widely available, and convenient disease detection product.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e07041"},"PeriodicalIF":14.3,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the molecular mechanisms underpinning the regulatory networks of microbes among themselves and with their host are still in infancy. Here, it is reported that Drosophila and the commensal Lactiplantibacillus plantarum form an alliance to compete with the pathogenic Serratia marcescens using the integrated three-species model system. In the dual-species model, larvae diminish the L. plantarum population, but reversibly increase lactate production through altering its transcriptional reprogramming. In the tripartite-species model, larvae facilitate the growth of L. plantarum that confers colonization resistance against S. marcescens. On the other hand, S. marcescens launches sophisticated arms race strategies to impair colonization resistance by sensing lactate derived from L. plantarum. More importantly, the S. marcescens population challenged with Drosophila and L. plantarum adaptively diverge into virulent and reduced virulence subclusters with an increase in resistance heterogeneity. To form the alliance with Drosophila, heterogeneity in lactate generation is broadened among L. plantarum subpopulations.

Since mitochondria are the primary source of ROS, targeting mitochondrial ROS is a promising strategy for periodontitis treatment. However, this alone cannot address the complex \"ROS-inflammation-hypoxia\" cycle in periodontitis, requiring a more comprehensive approach. Here, a natural enzyme cascade nanogel (TPP-SAT) composed of triphenylphosphine (TPP), superoxide dismutase (SOD), and catalase (CAT) via in-situ polymerization is developed. TPP-SAT targets mitochondrial ROS, converting ROS (such as H2O2 or ·O2 -) into O2 through the enzyme cascade of SOD and CAT. This alleviates hypoxia, prevents oxidative damage, and restores the balance between pro-inflammatory M1 and anti-inflammatory M2 macrophages, reducing inflammation and immune dysfunction. TPP-SAT breaks the \"ROS-inflammation-hypoxia\" cycle, inhibits alveolar bone resorption, and accelerates periodontal tissue regeneration.
