We report that circulating sphingosine 1-phosphate (S1P) carried by apolipoprotein M (ApoM) acts through the endothelial S1P receptor 1 (S1PR1) to suppress choroidal neovascularization (CNV) in mouse laser-induced CNV, modeling nAMD. In humans, low plasma ApoM levels were associated with increased choroidal and retinal pathology. Additionally, endothelial <i>S1pr1</i> knockout and overexpressing transgenic mice showed increased and reduced CNV lesion size, respectively. Systemic administration of ApoM-Fc, an engineered S1P chaperone protein, not only attenuated CNV to an equivalent degree as anti-VEGF antibody treatment but also suppressed pathological vascular leakage.

Recent studies have highlighted the importance of ubiquitinases in angiogenesis. In this study, we utilized RNA sequencing data of the mouse retinal development model from the GEO database to identify the potential proangiogenic deubiquitinases and found USP11 was significantly upregulated. Although USP11 is known to regulate cell survival, DNA repair, and oxidative stress in cancers and ischemic conditions, its direct role in endothelial angiogenesis remains poorly understood. Here, we demonstrated that USP11 expression correlates with key pro-angiogenic genes and is significantly upregulated at both mRNA and protein levels in VEGF-treated human umbilical vein endothelial cells (HUVECs). USP11 knockout markedly inhibited angiogenesis both in vivo and in vitro, whereas USP11 overexpression promoted angiogenesis. Mechanistically, USP11 binds to PRDX2, facilitating the removal of its K63-linked polyubiquitination, which promotes its translocation into the nucleus. This facilitates the concurrent nuclear translocation of c-MYC, a PRDX2 interactor, which subsequently enhances the transcription of <i>KDR</i> (encoding VEGFR2) and activates the VEGFR2 signaling pathway. Our findings suggest that USP11 promotes angiogenesis by upregulating VEGFR2 expression through the PRDX2/c-MYC pathway, indicating that USP11 could serve as a potential target for clinical interventions in angiogenesis-related diseases.</p></div>","PeriodicalId":7886,"journal":{"name":"Angiogenesis","volume":"28 2","pages":""},"PeriodicalIF":9.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801226","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}

Several molecular pathways have been implicated in VEGF-induced hyperpermeability, including binding of the VEGF-activated tyrosine kinase receptor VEGFR2 by the T-cell specific adaptor (TSAd) to recruit a SRC family kinase to induce junction opening between vascular endothelial cells (ECs). Inconsistent with a universal role for TSAd in permeability signalling, immunostaining approaches previously reported TSAd only in dermal and kidney vasculature. To address this discrepancy, we have mined publicly available omics data for expression of TSAd and other permeability-relevant signal transducers in multiple organs affected by VEGF-induced vascular permeability. Unexpectedly, TSAd transcripts were largely absent from EC single cell RNAseq data, whereas transcripts for other permeability-relevant signal transducers were detected readily. TSAd transcripts were also lacking from half of the EC bulk RNAseq datasets examined, and in the remaining datasets appeared at low levels concordant with models of leaky transcription. Epigenomic EC data located the TSAd promoter to closed chromatin in ECs, and mass spectrometry-derived EC proteomes typically lacked TSAd. By suggesting that TSAd is not actively expressed in ECs, our findings imply that TSAd is likely not critical for linking VEGFR2 to downstream signal transducers for EC junction opening.</p></div>","PeriodicalId":7886,"journal":{"name":"Angiogenesis","volume":"28 2","pages":""},"PeriodicalIF":9.2,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10456-025-09971-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These cells exhibit a superior proliferative capacity, robust ability to form vascular networks, and lower immunogenicity compared to adult and embryonic stem cell-derived counterparts. The immune-privileged characteristics of CB-ECFCs, including reduced expression of pro-inflammatory mediators and tolerance-inducing molecules such as HLA-G, further enhance their therapeutic potential. Their low immunogenicity minimizes the risk of immune rejection, making them suitable for allogenic cell therapies. Their application extends to complex tissue engineering and organ revascularization, where their ability to integrate into three-dimensional scaffolds and support vascular tree formation represents a significant advancement. Moreover, CB-ECFCs’ capability to adapt to inflammatory stimuli and retain immunological memory highlights their functional versatility in dynamic microenvironments. This review highlights the remarkable ontogeny of ECFCs while unveiling the unparalleled potential of CB-ECFCs in revolutionizing regenerative medicine. From pre-vascularizing engineered tissues and organoids to pioneering cell-based therapies for cardiovascular, dermatological, and degenerative diseases, CB-ECFCs stand at the forefront of cutting-edge biomedical advancements, offering unprecedented opportunities for therapeutic innovation. By leveraging their vasculogenic, immune-regulatory, and regenerative capacities, CB-ECFCs offer a robust alternative for addressing the challenges of vascular repair and organ engineering.

However, fully recreating human tissue microvasculatures is challenging given the multicellular complexity of the microvessel and microvessel-tissue interplay. Importantly, effective models should capture the dynamic activity of the perivascular cells of the perivascular niche, which are critical to tissue hemostasis and function. Isolated microvessel fragments from rodent adipose have been extensively studied and used in a variety of vascularization models. We have progressed this proven technology by deriving isolated fragments of intact human microvessels harvested from adipose (haMVs) to model human vascularization and advance human vascularized tissue models. Here we show the haMVs retain native microvessel structures, including perivascular cellularity, and recapitulate bona fide sprouting angiogenesis in vitro through distinct sprouting and neovessel elongation phases. As primary isolates, the angiogenic potential varies between donor lots and correlates with the presence of haMV perivascular cells. In an in vitro model of tumor angiogenesis, the addition of anti-tumor agents impacted tumor cell expansion in the presence of the haMVs but not endothelial cells alone demonstrating the importance of the perivascular cells in tissue modeling.

Moreover, aged ECs, especially in the venular subtype, exhibited a pseudotemporal transition to a terminal state characterized by diminished oxidative phosphorylation and strengthened cytokine signaling. Metabolic flux balance analysis predicted that among the 13 differentially expressed cytokines identified in aged EC subpopulations, Cxcl9 was strongly correlated with impaired oxidative phosphorylation in aged ECs. It was further validated using microvascular ECs treated with Cxcl9. Notably, the G protein-coupled receptor signaling pathway was subsequently suppressed, in which Aplnr suppression was also observed in aged ECs, contributing to their impaired energy metabolism and reduced angiogenesis.

Under physiological conditions, LSECs act as selective barriers, regulating substance exchange and hepatic blood flow. Interestingly, LSECs exhibit contrasting roles at different stages of disease progression: in the early stages, they actively resist disease advancement and help restore sinusoidal homeostasis; whereas in later stages, they contribute to disease worsening. During this transition, LSECs undergo capillarization, lose their characteristic markers, and become dysfunctional. As the disease progresses, LSECs closely interact with hepatocytes, hepatic stellate cells, various immune cells, and tumor cells, driving processes such as steatosis, inflammation, fibrosis, angiogenesis, and carcinogenesis.
