reticulocyte Med.|rɪˈtɪkjʊləʊsaɪt|
[f. reticulo- + -cyte.]
a. A red blood cell which has lost its nucleus but is not yet mature, characterized by a granular or reticulated appearance when suitably stained.
1922E. B. Krumbhaar in Jrnl. Lab. & Clin. Med. VIII. 11 The presence of reticulated or ‘skeined’ erythrocytes..in the peripheral blood..has..in the last decade..assumed clinical importance as an index of the activity of blood formation. I would suggest..that when the normal percentage of these cells in the peripheral blood is exceeded, the condition be designated ‘reticulosis’... The word ‘reticulocyte’ might similarly be substituted for ‘reticulated erythrocytes’. 1956Nature 28 Jan. 190/1 Although reticulocytes have practically their full complement of haemoglobin, evidence from amino-acid incorporation studies suggests that these cells, unlike mature erythrocytes, still have protein-synthesizing capacity. 1968H. Harris Nucleus & Cytoplasm i. 12 The mammalian reticulocyte continues to synthesize haemoglobin for some days after elimination of the cell nucleus.
b. attrib., as reticulocyte level; reticulocyte count, the proportion or concentration of reticulocytes in the blood.
1922E. B. Krumbhaar in Jrnl. Lab. & Clin. Med. VIII. 14 The temporary rise in the reticulocyte count immediately after transfusions were begun was found in another dog, and considered by us as probably due to bone marrow irritation. 1961Lancet 26 Aug. 490/1 The reticulocyte and platelet counts were 3·6% and 228,000 per c. mm. respectively. 1980Brit. Med. Jrnl. 29 Mar. 892/1 Thirty patients receiving haemodialysis..showed significant increases (p
1946Nature 2 Nov. 627/1 All the rabbits used in these experiments showed a normal reticulocyte level of 1·0–2·0 per cent. |
