    Boster Bio anti cd81
    NsPEFs engineering boosts the production of ADSCs-EVs with superior yield and stability A. Schematic illustration of the high-efficiency extraction of extracellular vesicles (EVs) from adipose-derived stem cells (ADSCs) using nanosecond pulsed electric fields (NsPEFs). B. Representative transmission electron microscopy (TEM) images of isolated Ctrl-ADSCs-EVs and NsPEFs-ADSCs-EVs, showing characteristic cup-shaped morphology and bilayer membrane (scale bars: 150 nm and 75 nm). C. Nanoparticle tracking analysis (NTA) showing the particle size distribution of EVs (n = 3). D. Western blot (WB) analysis confirming the positive expression of EV-specific markers <t>(CD81,</t> CD63, TSG101) and the absence of the negative markers (Calnexin, Histone H3, LaminA/C). Quantification is shown on the right (n = 3). E. The particle concentration of EVs. F. NsPEFs stimulation significantly enhanced both yield and protein output compared to Ctrl-ADSCs-EVs. G. Zeta potential measurement indicating colloidal stability (n = 3). H. Purity assessment expressed as the particle-to-protein ratio ( × 10 9 particles/μg). I. Viability of cells post-NsPEFs-ADSCs-EVs treatment assessed by trypan blue exclusion assay (scale bar: 1.7 mm). Data are presented as mean ± SEM from at least three independent experiments. Statistical significance was determined by unpaired two-tailed Student's t-test or one-way ANOVA with Tukey's post-hoc test. ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001, and ∗∗∗∗P < 0.0001; ns: not significant.

    Article Snippet: Background: Mesenchymal stem cell-derived exosomes (MSC-exosome), a promising cell-free strategy, show attractive applications in the treatment of osteoporosis.. Pretreatment of MSCs before application can effectively improve the therapeutic efficacy of MSC-exosomes.. Our study investigated the effects of exosomes from isobavachin (IBA)-pretreated human bone marrow-derived MSCs (hBMSCIBA-exosomes) on osteoporosis progression and further unveil the underlying molecular mechanism.
