+The origin of Reissner's fibre in an appendicularian, Oikopleura dioica
+
+The Reissner's fiber in _O. dioica_ is produced by a single ”fibrogen” cell.
+Electron microsocopy of this cell show a large perikaryon, cisternas, and a
+single cilium, which is inserted in the central canal.
- Two subchordal cells are found in the haemocel of the tail. Utrastructure analysis
suggests the alternance of highly exocytic and highly endocytic states
([[Fredriksson and Olsson, 1991|biblio/10.1111_j.1463-6395.1991.tb01203.x]]).

+ - The tail's neural tube has a ”fibrogen cell” at its anterior ends, which is
secreting the Reissner's fiber (reviewed in [[Olsson, 1993|biblio/10.1007_978-3-642-78013-4_5]]).
