Wnt signaling derived from the cortical hem, a signaling center, is crucial for telencephalic development including cortical patterning and the induction of hippocampal development. Secreted protein R-spondin (Rspo) 1–4 and their receptors, leucine-rich repeat-containing G-protein-coupled receptor (Lgr) 4–6, act as activators of Wnt signaling. Although Rspo expression in the hem during the early stages of cortical development has been reported, comparative expression analysis of Rspos and Lgr4–6 has not been performed. In this study, we examined the detailed spatiotemporal expression patterns of <em>Rspo1</em>–<em>4</em> and <em>Lgr4</em>–<em>6</em> in the embryonic and postnatal telencephalon to elucidate their functions. In the embryonic day (E) 10.5–14.5 telencephalon, <em>Rspo1</em>–<em>3</em> were prominently expressed in the cortical hem. Among their receptors, <em>Lgr4</em> was observed in the ventral telencephalon, and <em>Lgr6</em> was highly expressed throughout the telencephalon at the same stages. This suggests that <em>Rspo1–3</em> and <em>Lgr4</em> initially regulate telencephalic development in restricted regions, whereas <em>Lgr6</em> functions broadly. From the late embryonic stage, the expression areas of <em>Rspo1</em>–<em>3</em> and <em>Lgr4</em>–<em>6</em> dramatically expanded; their expression was found in the neocortex and limbic system, such as the hippocampus, amygdala, and striatum. Increased <em>Rspo</em> and <em>Lgr</em> expression from the late embryonic stages suggests broad roles of Rspo signaling in telencephalic development. Furthermore, the <em>Lgr</em><sup>+</sup> regions were located far from the <em>Rspo</em><sup>+</sup> regions, especially in the E10.5–14.5 ventral telencephalon, suggesting that Lgrs act via a Rspo-independent pathway.</p></div>","PeriodicalId":55598,"journal":{"name":"Gene Expression Patterns","volume":"49 ","pages":"Article 119333"},"PeriodicalIF":1.2,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10648888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the fully developed mouse placenta, nuclear hnRNPL was observed broadly in trophoblasts, whereas within the implantation site a discrete subset of cells showed hnRNPL outside the nucleus. In the first-trimester human placenta, hnRNPL was detected in the undifferentiated cytotrophoblasts, suggesting a role for this factor in trophoblast progenitors.
