Adjacent to the cysts were capillaries, allowing observation of peripheral blood cells. Numerous white blood cells displaying uncommon cytoplasmic projections were observed amongst the erythrocytes. Their morphology allowed them to be identified as thrombocytes (TCs). Each TC displayed 18\u201326 cytoplasmic projections, most of which were in close proximity to erythrocytes. At their apical end, each cytoplasmic projection presented an ellipsoidal vacuole (<jats:italic>c.<\/jats:italic> 0\u00b76\u2009\u00b5m\u2009\u00d7\u20090\u00b73\u2009\u00b5m) from which a secretory tubule, 0\u00b73\u20130\u00b74\u2009\u00b5m long and <jats:italic>c.<\/jats:italic> 120\u2009nm in total diameter, extended towards the periphery of the TC plasmalemma and fused with the cellular membrane. From this opening, contents of vacuoles were apparently released into the lumen of the capillaries. Other vacuoles with similar features, and containing an electron\u2010lucent matrix, were observed in the cytoplasm of the TC. This is the first description of fish TC with these ultrastructural features and organization, which suggest that they perform a secretory function.<\/jats:p>","DOI":"10.1111\/jfb.12261","type":"journal-article","created":{"date-parts":[[2014,3,7]],"date-time":"2014-03-07T10:24:54Z","timestamp":1394187894000},"page":"865-871","source":"Crossref","is-referenced-by-count":3,"title":["Ultrastructure of novel thrombocytes in the dog snapper <i>Lutjanus jocu<\/i>"],"prefix":"10.1111","volume":"84","author":[{"given":"C.","family":"Azevedo","sequence":"first","affiliation":[{"name":"Laboratory of Cell Biology Institute of Biomedical Sciences (ICBAS\/UP), University of Porto 4050\u2010313 Porto Portugal"},{"name":"Laboratory of Pathology Interdisciplinary Centre of Marine and Environmental Research (CIIMAR\/CIMAR\/UP), University of Porto 4050\u2010123 Porto Portugal"},{"name":"Zoology Department College of Science, King Saud University 11451 Riyadh Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Matos","sequence":"additional","affiliation":[{"name":"Edilson Matos Research Laboratory Federal University of Par\u00e1 (UFPa) 66000 Bel\u00e9m Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Rocha","sequence":"additional","affiliation":[{"name":"Laboratory of Pathology Interdisciplinary Centre of Marine and Environmental Research (CIIMAR\/CIMAR\/UP), University of Porto 4050\u2010123 Porto Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Matos","sequence":"additional","affiliation":[{"name":"Carlos Azevedo Research Laboratory Federal Rural University of Amazonia (UFRA) 66077 Bel\u00e9m Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Laboratory of Cell Biology Institute of Biomedical Sciences (ICBAS\/UP), University of Porto 4050\u2010313 Porto Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Al\u2010Quraishy","sequence":"additional","affiliation":[{"name":"Zoology Department College of Science, King Saud University 11451 Riyadh Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Casal","sequence":"additional","affiliation":[{"name":"Laboratory of Pathology Interdisciplinary Centre of Marine and Environmental Research (CIIMAR\/CIMAR\/UP), University of Porto 4050\u2010123 Porto Portugal"},{"name":"Department of Sciences High Institute of Health Sciences (CESPU) 4585\u2010116 Gandra Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,3,7]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"crossref","unstructured":"Azevedo C.
