In this study, we examined the efficacy of delayed poststroke treatment (post 3\u20138 days) of the sonic hedgehog pathway agonist on functional recovery and the underlying mechanisms.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods\u2014<\/jats:title>\n            <jats:p>We evaluated functional recovery at 1 month after stroke using locomotion analysis and Barnes maze test for cognitive function. We used a genetically inducible neural stem cell\u2013specific reporter mouse line (nestin-CreERT2-R26R-YFP) to label and track their proliferation, survival, and differentiation in ischemic brain. Brain tissue damage, angiogenesis, and cerebral blood flow recovery was evaluated using magnetic resonance imaging techniques and immunostaining.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results\u2014<\/jats:title>\n            <jats:p>Our results show that delayed treatment of sonic hedgehog pathway agonist in stroke mice results in enhanced functional recovery both in locomotor function and in cognitive function at 1 month after stroke. Furthermore, using the Nestincre-ERT2-YFP mice, we showed that poststroke sonic hedgehog pathway agonist treatment increased surviving newly born cells derived from both subventricular zone and subgranular zone neural stem cells, total surviving DCX+ (Doublecortin) neuroblast cells, and neurons (NeuN+\/YFP+) in the ischemic brain. Sonic hedgehog pathway agonist treatment also improved the brain tissue repair in ischemic region supported by our T2-weighted magnetic resonance imaging, cerebral blood flow map by arterial spin labeling, and immunohistochemistry (\u03b1-smooth muscle actin and CD31 immunostaining).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>These data confirm an important role for the hedgehog pathway in poststroke brain repair and functional recovery, suggesting a prolonged treatment window for potential treatment strategy to modulate sonic hedgehog pathway after stroke.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/strokeaha.117.016650","type":"journal-article","created":{"date-parts":[[2017,5,10]],"date-time":"2017-05-10T00:50:30Z","timestamp":1494377430000},"page":"1636-1645","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":84,"title":["Poststroke Sonic Hedgehog Agonist Treatment Improves Functional Recovery by Enhancing Neurogenesis and Angiogenesis"],"prefix":"10.1161","volume":"48","author":[{"given":"Yongming","family":"Jin","sequence":"first","affiliation":[{"name":"From the Department of Neurological Surgery (Y.J., A.B., Y.L.) and Department of Biomedical Engineering (Y.Z., X.Y.), Case Western Reserve University, Cleveland, OH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Austin","family":"Barnett","sequence":"additional","affiliation":[{"name":"From the Department of Neurological Surgery (Y.J., A.B., Y.L.) and Department of Biomedical Engineering (Y.Z., X.Y.), Case Western Reserve University, Cleveland, OH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifan","family":"Zhang","sequence":"additional","affiliation":[{"name":"From the Department of Neurological Surgery (Y.J., A.B., Y.L.) and Department of Biomedical Engineering (Y.Z., X.Y.), Case Western Reserve University, Cleveland, OH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Yu","sequence":"additional","affiliation":[{"name":"From the Department of Neurological Surgery (Y.J., A.B., Y.L.) and Department of Biomedical Engineering (Y.Z., X.Y.), Case Western Reserve University, Cleveland, OH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Luo","sequence":"additional","affiliation":[{"name":"From the Department of Neurological Surgery (Y.J., A.B., Y.L.) and Department of Biomedical Engineering (Y.Z., X.Y.), Case Western Reserve University, Cleveland, OH."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0804656"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.2129-13.2013"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0038932"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/0271678X16674487"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/nm747"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12975-016-0490-6"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(16)31259-4"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.4531-07.2007"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1634\/stemcells.2008-0297"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.3171\/2012.1.JNS111285"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1038\/cddis.2014.446"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0124657"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1038\/nprot.2012.123"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.3812-07.2007"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/glia.21033"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.2042-13.2013"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.conb.2013.09.004"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(09)70061-4"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.4323-06.2006"},{"key":"e_1_3_3_21_2","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhr302"},{"key":"e_1_3_3_22_2","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.109.561951"},{"key":"e_1_3_3_23_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.32.8.1890"},{"key":"e_1_3_3_24_2","first-page":"637","article-title":"Evolution of apparent diffusion coefficient, diffusion-weighted, and T2-weighted signal intensity of acute stroke.","volume":"22","author":"Lansberg MG","year":"2001","unstructured":"Lansberg MG, Thijs VN, O\u2019Brien MW, Ali JO, de Crespigny AJ, Tong DC, et al..
