cytoblasteman.

Brit.

/ˌsʌɪtə(ʊ)blaˈstiːmə/, U.S.

/ˌsaɪdəblæˈstimə/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: cyto- comb. form, blastema n.

Etymology: < cyto- comb. form + blastema n., after German Cytoblastema ( T. Schwann Mikrosk. Untersuchungen (1839) ii. 45). Compare earlier cytoblast n.

Biology. Now historical.

A structureless fluid held to be the substance from which cells are formed.

1860 F. Chance tr. R. Virchow Cellular Pathol. i. 15 According to Schwann, the intercellular substance was the cytoblastema, destined for the development of new cells. This I do not consider to be correct.

1931 Science 20 Mar. 298/1 Almost a century ago, Schwann described the cells as surrounded by a fluid, the cytoblastema, containing the material necessary for their nutrition.

1998 Endeavour 22 115/2 Would not this factor be precisely the power of crystallization, which Schwann attributed to the primordial nutritive fluid named ‘cytoblastema’?
