Here, we show that PRC2, which catalyzes H3K27me3, binds both classic Polycomb targets and noncanonical H3K27me3 domains in growing oocytes but dissociates from chromatin in fully grown oocytes. After fertilization, PRC2 rebinds noncanonical H3K27me3 domains before relocating to Polycomb targets in blastocysts. Interestingly, the binding and activity of PRC2 are restricted by a maternal inhibitory factor, EZH inhibitory protein (EZHIP), which co-binds with PRC2. Upon knockout of Ezhip, hyperactive PRC2 promiscuously deposits H3K27me3 genome-wide. This overwrites H3K27me3 memories at noncanonical imprinted genes and paradoxically causes derepression of H3K27me3 targets, defective X chromosome inactivation, and diluted chromatin PRC2. H3K27me3 restoration at Polycomb targets after implantation is also attenuated, accompanied by sub-lethality. These data unveil principles of epigenetic inheritance that both insufficient and excessive heterochromatic marks cause loss of epigenetic memories and repression.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":"25 1","pages":""},"PeriodicalIF":23.9,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145338563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the potential of a single pharmaceutical agent to mitigate primate ovarian aging remains largely unexplored. Our 3.3-year study in monkeys demonstrates that oral vitamin C has geroprotective effects against ovarian aging. Vitamin C diminishes key aging biomarkers, including oxidative stress and follicular depletion. Using a single-cell transcriptomic clock, we show that vitamin C can reduce the biological age of oocytes by 1.35 years and somatic cells by 5.66 years. This effect is partly mediated by the NRF2 pathway, which alleviates ovarian cell senescence and inflammation. Our findings highlight the role of vitamin C in combating primate ovarian aging and provide insights for developing interventions against human ovarian aging.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":"54 1","pages":""},"PeriodicalIF":23.9,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145283471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how these signals integrate into developmental circuits remains poorly understood. Here, we developed a light-inducible strategy to induce BMP4 signaling with precise spatial coordinates in human pluripotent stem cells. Light-controlled BMP4 induces SMAD1–5 phosphorylation, resulting in amnion differentiation, and relies on a tension-dependent induction of WNT and NODAL for mesoderm differentiation. In response to BMP4 signaling, the mechanosensitive transcription factor YAP1 accumulates in the nucleus, where it represses WNT3 mRNA, regulating the induction of the three germ layers. Based on these findings, we developed a mathematical model that integrates tissue mechanics into morphogen dynamics, quantitatively explaining tissue-scale responses to BMP4 signaling. Thus, light induction of the morphogen BMP4 in human stem cell models elucidated the interplay between tissue mechanics and signaling at the onset of gastrulation.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":"9 1","pages":""},"PeriodicalIF":23.9,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145283472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we show that hypoxia directly regulates human lung epithelial cell identity using tissue-derived organoids. Fetal multipotent lung epithelial progenitors remain undifferentiated in a self-renewing culture condition under normoxia but spontaneously differentiate toward multiple airway cell types and inhibit alveolar differentiation under hypoxia. Using chemical and genetic tools, we demonstrate that hypoxia-induced airway differentiation depends on hypoxia-inducible factor (HIF) activity, with HIF1α and HIF2α differentially regulating progenitor fate decisions. KLF4 and KLF5 are direct HIF targets that promote basal and secretory cell fates. Moreover, hypoxia is sufficient to convert alveolar type 2 cells derived from both human fetal and adult lungs to airway cells, including aberrant basal-like cells that exist in human fibrotic lungs. These findings reveal roles for hypoxia and HIF activity in the developing human lung epithelium and have implications for aberrant cell fate changes in pathological lungs.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":"109 1","pages":""},"PeriodicalIF":23.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
