All mice from 5 independently derived transgenic lines exhibited either one or both of two types of congenital spinal cord pathologies: failure of the neural tube to close (spina bifida) and multiple neural tubes (diastematomyelia). Because the transgene is expressed only in a restricted caudal region and only for a brief interval (E8.5 to E13.5), there was no evidence of embryonic lethality. The dysraphisms develop during the period and within the zone of transgene expression. We present evidence that these dysraphisms result from an inhibition of neuropore closure and a stimulation of secondary neurulation. After transgene expression ceases, the spinal dysraphisms are progressively resolved and the neonatal animals, while showing signs of scarring and tissue resorption, have a closed vertebral column. The multiple spinal cords remain but are enclosed in a single spinal column as in the human diastematomyelia. The animals live a normal life time, are fertile and do not exhibit any obvious weakness or motor disabilities.<\/jats:p>","DOI":"10.1242\/dev.129.16.3957","type":"journal-article","created":{"date-parts":[[2021,4,26]],"date-time":"2021-04-26T05:02:48Z","timestamp":1619413368000},"page":"3957-3964","source":"Crossref","is-referenced-by-count":22,"title":["Ectopic expression of<i>Gcm1<\/i>induces congenital spinal cord abnormalities"],"prefix":"10.1242","volume":"129","author":[{"given":"Brahim","family":"Nait-Oumesmar","sequence":"first","affiliation":[{"name":"Department of Molecular, Cellular and Developmental Biology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Stecca","sequence":"additional","affiliation":[{"name":"Department of Molecular, Cellular and Developmental Biology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Girish","family":"Fatterpekar","sequence":"additional","affiliation":[{"name":"Department of Radiology, Mount Sinai School of Medicine, One Gustave L.
