However, it has been argued that prior to emergence of leftward flow an additional mechanism operates during early cleavage stages in\r\n Xenopus\r\n embryo which is based on cytoskeletal processes. Evidence in favour of this early mechanism was supported by left-right abnormalities after chemical inhibition of cytoskeletal protein formin. Here we analyzed temporal dimension of this effect in detail and found that reported abnormalities arise only after treatment at gastrula-neurula stages, i.e. just prior to and during the operation of left-right organizer. Moreover, molecular and morphological analysis of the left-right organizer reveals its abnormal development. Our results strongly indicate that left-right abnormalities reported after formin inhibition cannot serve as support of models based on early symmetry breaking event in\r\n Xenopus\r\n embryo."],["dc.description.sponsorship"," Lomonosov Moscow State University http://dx.doi.org/10.13039/501100016971"],["dc.description.sponsorship"," Koltzov Institute of Developmental Biology, Russian Academy of Sciences http://dx.doi.org/10.13039/501100014785"],["dc.description.sponsorship","Göttingen University"],["dc.identifier.doi","10.1371/journal.pone.0275164"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/118169"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-621"],["dc.relation.eissn","1932-6203"],["dc.rights.uri","http://creativecommons.org/licenses/by/4.0/"],["dc.title","Abnormal left-right organizer and laterality defects in Xenopus embryos after formin inhibitor SMIFH2 treatment"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
