Researchers have now transplanted forebrain organoids, colonized by stem-cell-derived microglial cells, into mice brains. And indeed, the stem-cell-derived microglial cells developed human-microglia-like transcriptomic and functional characteristics. This made it possible, for the first time, to study in-vivo immune responses in organoids derived from stem cell lines from patients with ASD and macrocephaly.","PeriodicalId":475844,"journal":{"name":"New Ground","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136208435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rapidly growing body of high-precision cosmological data, however, has moved beyond the standard model’s ability to explain it. One possible culprit: the set of simplistic, built-in assumptions regarding the time-dependent form of the universal expansion factor, which are poorly motivated by fundamental theory.","PeriodicalId":475844,"journal":{"name":"New Ground","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136008258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
