Although seizure etiology is increasingly understood, the pathophysiological mechanisms contributing to cognitive decline and epilepsy progression remain less recognized. We have previously shown that adult hippocampal neurogenesis dramatically declines in MTLE patients with increased disease duration. Here, we investigate when multiple cognitive domains become affected during epilepsy progression and how human neurogenesis levels contribute to it. We find that intelligence, verbal learning, and memory decline at a critical period of 20 years disease duration. In contrast to rodents, the number of human immature neurons positively associates with auditory verbal, rather than visuospatial, learning and memory. Moreover, this association does not apply to mature granule neurons. Our study provides cellular evidence of how adult neurogenesis corresponds with human cognition and signifies an opportunity to advance regenerative medicine for patients with MTLE and other cognitive disorders.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":"36 1","pages":""},"PeriodicalIF":23.9,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142776745","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}

Our developmentally inspired method uses self-organization of human hematopoietic stem and progenitor cells and vascular endothelial cells cultured in a three-dimensional microphysiological system to create vascularized, perfusable tissue constructs that resemble the hematopoietic vascular niche of the human marrow. The microengineered niche is capable of multilineage hematopoiesis and can generate functionally mature human myeloid cells that can intravasate into perfused blood vessels, providing a means to model the mobilization of innate immune cells from the marrow. We demonstrate the application of this system by presenting a specialized model of ionizing radiation-induced bone marrow injury and a multiorgan model of acute innate immune responses to bacterial lung infection. Furthermore, we introduce an advanced platform that enables large-scale integration and automated experimentation of the engineered hematopoietic tissues for preclinical screening of myelotoxicity due to anti-cancer drugs.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":"77 1","pages":""},"PeriodicalIF":23.9,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142776507","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}

The lack of robust disease models for VMs impedes drug discovery. Here, we devise a robust protocol for the generation of human induced VECs (iVECs) through manipulation of cell-cycle dynamics via the retinoic signaling pathway. We introduce an L914F mutation into the TIE2 gene locus of induced pluripotent stem cells (iPSCs) and show that the mutated iVECs form dilated blood vessels after transplantation into mice, thereby recapitulating the phenotypic characteristics observed in VMs. Moreover, utilizing a deep neural network and a high-throughput digital RNA with perturbation of genes sequencing (DRUG-seq) approach, we perform drug screening and demonstrate that bosutinib effectively rescues the disease phenotype in vitro and in vivo.

However, its utility after ex vivo gene therapy in human HSPCs remains unexplored. We show that administering G-CSF from day 1 to 14 post-transplant impedes engraftment of CRISPR-Cas9 gene-edited human HSPCs in murine xenograft models. G-CSF affects gene-edited HSPCs through a cell-intrinsic mechanism, causing proliferative stress and amplifying the early p53-mediated DNA damage response triggered by Cas9-mediated DNA double-strand breaks. This underscores a threshold mechanism where p53 activation must reach a critical level to impair cellular function. Transiently inhibiting p53 or delaying the initiation of G-CSF treatment to day 5 post-transplant attenuates its negative impact on gene-edited HSPCs. The potential for increased HSPC toxicity associated with post-transplant G-CSF administration in CRISPR-Cas9 autologous HSPC gene therapy warrants consideration in clinical trials.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":"107 1","pages":""},"PeriodicalIF":23.9,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599608","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}
