Microtubule-organizing centres (MTOCs) at both ends and near the middle of each cell act in concert during control of microtubule positioning. In addition, the three cell surface-associated microtubule-organizing centres are involved in coordinating the connection of bundle microtubules to cytoskeletal components in neighbouring cells and to a basement membrane.<\/jats:p>\n               <jats:p>The precisely defined locations of the three MTOCs specify the cell surface regions where microtubule ends will finally be anchored. The MTOCs are modified as anchorage proceeds. Substantial fibrous meshworks assemble at the surface sites occupied by the MTOCs and link microtubule ends to cell junctions. This procedure also connects the microtubule bundle to cytoskeletal arrays in neighbouring cells at two of the MTOC sites, and to the basilar membrane (a substantial basement membrane) in the case of the third site. A fourth meshwork that is not positioned at a major MTOC site is involved in connecting one side of the microtubule bundle to the cytoskeletons of two other cell neighbours. The term surfoskelosome is suggested for such concentrations of specialized cytoskeletal materials and junctions at cell surface anchorages for cytoskeletal arrays.<\/jats:p>\n               <jats:p>The large microtubule bundle in each cell is composed of two closely aligned microtubule arrays. Bundle assembly begins with nucleation of microtubules by a centrosomal MTOC that is attached to the apical cell surface. These microtubules elongate downwards and the plus ends of many of them are apparently captured by a basal MTOC that is attached to the plasma membrane at the bottom of the cell. In the lower portion of the cell, the microtubule bundle also includes a basal array of microtubules but these elongate in the opposite direction. This investigation provides evidence that they extend upwards from the basal MTOC to be captured by a medial MTOC which is attached to the plasma membrane and situated near the mid-level of the cell. However, there are sub-stantial indications that the basal array\u2019s microtubules are also nucleated by the apically situated centrosomal MTOC, but escape from it, and are translocated downwards for capture of their plus ends by the basal MTOC. If this is the case, then these microtubules continue to elongate after translocation and extend back up to the medial MTOC, which captures their minus ends.<\/jats:p>","DOI":"10.1242\/jcs.108.1.37","type":"journal-article","created":{"date-parts":[[2021,4,24]],"date-time":"2021-04-24T02:43:22Z","timestamp":1619232202000},"page":"37-50","source":"Crossref","is-referenced-by-count":54,"title":["Three microtubule-organizing centres collaborate in a mouse cochlear epithelial cell during supracellularly coordinated control of microtubule positioning"],"prefix":"10.1242","volume":"108","author":[{"given":"Craig G.","family":"Henderson","sequence":"first","affiliation":[{"name":"University of St Andrews, St Andrews, Fife KY16 9TS 1 School of Biological and Medical Sciences, Bute Medical Building , , Scotland"},{"name":"Syracuse University, Syracuse 2 Department of Bioengineering and Neuroscience, The Institute for Sensory Research , , New York 13244-5290, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John B.","family":"Tucker","sequence":"additional","affiliation":[{"name":"University of St Andrews, St Andrews, Fife KY16 9TS 1 School of Biological and Medical Sciences, Bute Medical Building , , Scotland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mette M.","family":"Mogensen","sequence":"additional","affiliation":[{"name":"University of St Andrews, St Andrews, Fife KY16 9TS 1 School of Biological and Medical Sciences, Bute Medical Building , , Scotland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John B.","family":"Mackie","sequence":"additional","affiliation":[{"name":"University of St Andrews, St Andrews, Fife KY16 9TS 1 School of Biological and Medical Sciences, Bute Medical Building , , Scotland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark A.","family":"Chaplin","sequence":"additional","affiliation":[{"name":"University of St Andrews, St Andrews, Fife KY16 9TS 1 School of Biological and Medical Sciences, Bute Medical Building , , Scotland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norma B.","family":"Slepecky","sequence":"additional","affiliation":[{"name":"Syracuse University, Syracuse 2 Department of Bioengineering and Neuroscience, The Institute for Sensory Research , , New York 13244-5290, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorna M.","family":"Leckie","sequence":"additional","affiliation":[{"name":"University of St Andrews, St Andrews, Fife KY16 9TS 1 School of Biological and Medical Sciences, Bute Medical Building , , Scotland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"237","published-online":{"date-parts":[[1995,1,1]]},"reference":[{"key":"2023122400543595600_JOCES_108_1_37C1","doi-asserted-by":"publisher","first-page":"49","DOI":"10.3109\/00016487209122689","article-title":"Supporting elements in the organ of Corti.
