haemocytehemocyten.

Brit.

/ˈhiːmə(ʊ)sʌɪt/, U.S.

/ˈhiməˌsaɪt/

Forms: 1800s– haemocyte, 1900s– hemocyte (chiefly U.S.).

Origin: Formed within English, by compounding. Etymons: haemo- comb. form, -cyte comb. form.

Etymology: < haemo- comb. form + -cyte comb. form.

Medicine and Zoology.

A blood cell; (originally) †an erythrocyte (obsolete); (later) a blood cell of the haemolymph of various invertebrates, esp. arthropods, typically involved in clotting mechanisms and the immune response rather than containing respiratory pigments.

1888 Lancet 8 Dec. 1131/1 The blood showed diminution of haemocytes and haemoglobin only when there was haemorrhage.

1924 Biol. Bull. 46 248 Since hemocytes are lacking in this species it may be assumed that these cells are oxygen-carrying cells.

1947 A. D. Imms Outl. Entomol. (ed. 3) ii. 58 The blood or haemolymph is either clear or tinged with green or yellow pigment. Suspended in this fluid are numerous colourless blood cells or haemocytes.

1990 EMBO Jrnl. 9 2974/2 It appears likely that the immune response is regulated through a complex interaction between microbes, hemocytes, fat body cells and damaged cells in other tissues.
