Applying SmC-seq to mouse post-implantation development revealed a clear spatial heterogenous pattern of DNA methylation in inner cell mass-derived tissues. We identified a two-layer organization in the E8.5 ectoplacental cone with distinct methylation and proliferation states. Unexpectedly, a portion of maternal tissue with low DNA methylation level, enriched for nutrient-supplier progenitors, is observed in the middle region of decidua post-implantation. The hypomethylated regions in the nutrient-supplier progenitor cluster are associated with cell proliferation. Notably, the genes associated with hypomethylated regions in mature nutrient-supplier cluster are enriched in exocytosis and nutrient synthesis, linked to nutrient provision for embryogenesis before placental function.

To address this challenge, we adapt the concept of multifactor authentication (MFA) from computer science, and apply it to EV analysis. Similar to requiring multiple credentials to confirm digital identity, MFA in EV research integrates structural and molecular features to validate vesicle identity within heterogeneous mixtures and resolve subpopulations down to the single-EV level. By cross-validating across distinct factors and standardizing a multistep pipeline, MFA has the potential to enhance specificity, reliability, reproducibility and biological interpretability in EV analysis. Although no single approach fulfills all MFA criteria, several existing approaches embody MFA-like features. In this Perspective, we introduce MFA, discuss MFA-like approaches for EV subpopulation and single-EV analyses, highlight implications for EV biology and translational applications, and outline future directions for implementing an idealized MFA framework.</p>","PeriodicalId":18981,"journal":{"name":"Nature Methods","volume":" ","pages":""},"PeriodicalIF":32.1,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147776965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
