Here, we outline an approach for high-yield derivation of mDA neurons that principally differs from alternative technologies by utilizing retinoic acid (RA) signaling, instead of WNT and FGF8 signaling, to specify mesencephalic fate. Unlike most morphogen signals, where precise concentration determines cell fate, it is the duration of RA exposure that is the key-parameter for mesencephalic specification. This concentration-insensitive patterning approach provides robustness and reduces the need for protocol-adjustments between hPSC-lines. RA-specified progenitors promptly differentiate into functional mDA neurons in vitro, and successfully engraft and relieve motor deficits after transplantation in a rat PD model. Our study provides a potential alternative route for cell therapy and disease modelling that due to its robustness could be particularly expedient when use of autologous- or immunologically matched cells is considered.", "doi": "10.1038/s41467-022-30777-8", "pmid": "35650213", "labels": {"National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics Production)": "Service", "NGI Short read": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC9160024"}, {"db": "pii", "key": "10.1038/s41467-022-30777-8"}], "notes": [], "created": "2022-08-19T08:37:46.809Z", "modified": "2024-01-16T13:48:36.237Z"}, {"entity": "publication", "iuid": "2a387a31c3c54f2f9d3abce4e7efdfe2", "links": {"self": {"href": "https://publications.scilifelab.se/publication/2a387a31c3c54f2f9d3abce4e7efdfe2.json"}, "display": {"href": "https://publications.scilifelab.se/publication/2a387a31c3c54f2f9d3abce4e7efdfe2"}}, "title": "A Shh/Gli-driven three-node timer motif controls temporal identity and fate of neural stem cells.", "authors": [{"family": "Dias", "given": "Jos\u00e9 M", "initials": "JM", "orcid": "0000-0002-1402-0323", "researcher": {"href": "https://publications.scilifelab.se/researcher/82499805c5c24c46b8c2ec6427345c89.json"}}, {"family": "Alekseenko", "given": "Zhanna", "initials": "Z", "orcid": "0000-0002-6560-9699", "researcher": {"href": "https://publications.scilifelab.se/researcher/d78aae6139714fa3ae8221f3fb380b5a.json"}}, {"family": "Jeggari", "given": "Ashwini", "initials": "A", "orcid": "0000-0002-7155-9050", "researcher": {"href": "https://publications.scilifelab.se/researcher/083131be9eab46df9c789fb018316dff.json"}}, {"family": "Boareto", "given": "Marcelo", "initials": "M", "orcid": "0000-0002-9915-6376", "researcher": {"href": "https://publications.scilifelab.se/researcher/992734ee2f564e51b65c3d24770cc337.json"}}, {"family": "Vollmer", "given": "Jannik", "initials": "J", "orcid": "0000-0001-8341-7730", "researcher": {"href": "https://publications.scilifelab.se/researcher/793924a7af814c28a4ad66ff2fabf136.json"}}, {"family": "Kozhevnikova", "given": "Mariya", "initials": "M", "orcid": "0000-0001-9177-6303", "researcher": {"href": "https://publications.scilifelab.se/researcher/a7a4bfdfbcc54403b818b31b24934151.json"}}, {"family": "Wang", "given": "Hui", "initials": "H", "orcid": "0000-0002-5444-1579", "researcher": {"href": "https://publications.scilifelab.se/researcher/38fc15d279b34209a72be7bd71a9338c.json"}}, {"family": "Matise", "given": "Michael P", "initials": "MP", "orcid": "0000-0003-2998-9927", "researcher": {"href": "https://publications.scilifelab.se/researcher/f861ea74deb9478fa475c5036333dfd9.json"}}, {"family": "Alexeyenko", "given": "Andrey", "initials": "A", "orcid": "0000-0001-8812-6481", "researcher": {"href": "https://publications.scilifelab.se/researcher/54b6c0ff12c148dd803f7f72c8af0d14.json"}}, {"family": "Iber", "given": "Dagmar", "initials": "D", "orcid": "0000-0001-8051-1035", "researcher": {"href": "https://publications.scilifelab.se/researcher/26137676787f477fb374d629819d898b.json"}}, {"family": "Ericson", "given": "Johan", "initials": "J", "orcid": "0000-0002-8019-7127", "researcher": {"href": "https://publications.scilifelab.se/researcher/5a093b1609b74f74a8a8546f02946782.json"}}], "type": "journal article", "published": "2020-09-00", "journal": {"title": "Sci Adv", "issn": "2375-2548", "issn-l": "2375-2548", "volume": "6", "issue": "38", "pages": null}, "abstract": "How time is measured by neural stem cells during temporal neurogenesis has remained unresolved. By combining experiments and computational modeling, we define a Shh/Gli-driven three-node timer underlying the sequential generation of motor neurons (MNs) and serotonergic neurons in the brainstem. The timer is founded on temporal decline of Gli-activator and Gli-repressor activities established through down-regulation of Gli transcription. The circuitry conforms an incoherent feed-forward loop, whereby Gli proteins not only promote expression of Phox2b and thereby MN-fate but also account for a delayed activation of a self-promoting transforming growth factor-\u03b2 (Tgf\u03b2) node triggering a fate switch by repressing Phox2b. Hysteresis and spatial averaging by diffusion of Tgf\u03b2 counteract noise and increase temporal accuracy at the population level, providing a functional rationale for the intrinsically programmed activation of extrinsic switch signals in temporal patterning. Our study defines how time is reliably encoded during the sequential specification of neurons.", "doi": "10.1126/sciadv.aba8196", "pmid": "32938678", "labels": {"NGI Stockholm (Genomics Production)": "Service", "National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics Applications)": "Service", "Bioinformatics Support and Infrastructure": "Collaborative", "Bioinformatics Support, Infrastructure and Training": "Collaborative", "Bioinformatics Support for Computational Resources": "Service", "Bioinformatics (NBIS)": "Collaborative"}, "xrefs": [{"db": "pii", "key": "6/38/eaba8196"}, {"db": "pmc", "key": "PMC7494341"}], "notes": [], "created": "2020-12-07T16:28:52.509Z", "modified": "2024-01-16T13:48:41.848Z"}]}
