[ad. G. thrombocyt (M. C. Dekhuyzen 1892, in Verh. d. Anat. Ges. 94): see thrombo- and -cyte.]
a. A spindle-cell of the lower vertebrates, responsible for the clotting of blood.
1893Jrnl. R. Microsc. Soc. 25 In analogy with Löwit's nomenclature he uses the ending ‘blast’ for young forms, and ‘cyt’ for those which are adult. He distinguishes..thromboblasts and thrombocytes, as the ‘spindles’ of Eberth and Schimmelbusch may be called. 1910Jrnl. Morphol. XXI. 273 The spindle cells or thrombocytes of certain amphibian blood have a cytoplasm which stains in the same way as does that of the megakaryocyte. 1979Nature 1 Mar. 13/1 The rapid adhesion of platelets (or of their non-mammalian counterpart, the thrombocytes) to the vascular wall when the endothelial lining is breached has been a subject of interest since Wharton-Jones showed in 1851 that thrombocytes accumulated at points of local damage in blood vessels of the frog's foot.
b. A blood platelet.
1907E. A. Schäfer Essent. Histol. (ed. 7) 35 These often seem to radiate from minute round colourless discoid particles less than one-third the diameter of a red corpuscle... These are the..blood-platelets, or thrombocytes. 1938W. Magner Textbk. Hematol. i. 1 The cellular elements of the blood are of three types: red corpuscles or erythrocytes, white corpuscles or leukocytes, and platelets or thrombocytes. 1977J. Raynor Anat. & Physiol. x. 245 There are about 150,000–300,000 thrombocytes per cubic millimeter of blood. |
