Marcus Hartog's name for: a multinucleate (coenocytic) gametangium occurring in certain fungi, which is capable of uniting with another such structure in a process analogous to the fusion of gametes. Cf. zygotoid n. at zygote n. Derivatives. Obsolete. rare.
ΚΠ
1891 M. Hartog in Nature 17 Sept. 484/1 In apocytial fungi multinucleated masses of protoplasm (gametoids) may conjugate to form a zygotoid.
1892 M. Hartog in Q. Jrnl. Microsc. Sci. 33 21 In the two former genera all the protoplasm goes into the gametoid.
B. adj.

1903 Brit. Med. Jrnl. 26 Dec. 1664/1 To emphasize the similarity existing between malignant tissue and that which is normal in the sexual reproductive glands, the authors propose to introduce the term ‘gametoid’ to express the former.
1904 Proc. Royal Soc. 1903–4 72 503 The evidence justifies us in deliberately correlating the appearance of these ‘gametoid’ neoplasms with the result of a stimulus which has changed the normal somatic course of cell development into that characteristic of reproductive (not embryonic) tissue.
1907 Lancet 15 June 1662/1 Moreover, Victor Bonney has clearly shown that ‘gametoid’ mitoses are not specially characteristic of the cells of malignant growths.
1908 Practitioner Feb. 226 Neither gametoid cells, nor flagellated forms of this parasite, have been observed.
1965 Brit. Med. Jrnl. 8 May 1246 The time may come when the hitherto dominant somatic side of the cell wanes and the suppressed gametoid side attempts to express itself by changes in the chromosomes.
