Rouget cell Histology.|ruːʒeɪ|
Also Rouget's cell.
[tr. G. Rougetsche zelle (B. J. Vimtrup 1922, in Zeitschr. f. Anat. u. Entwicklungsges. LXV. 178), f. the name of C. M. B. Rouget (1824–1904), French physiologist, who described such cells in 1873 (Arch. de Physiol. V. 603).]
= pericyte.
1922A. Krogh Anat. & Physiol. Capillaries iii. 54 As there can be no doubt that the richly ramified muscle cells on the capillary wall are the same as those originally found by Rouget in the hyaloid membrane, Vimtrup has named them after the first discoverer, and we shall speak of them henceforth as Rouget cells. 1928[see pericyte]. 1939W. E. Le Gros Clark Tissues of Body vii. 158 In appearance, Rouget cells (or pericytes, as they have been called), are quite similar to connective-tissue cells. Ibid. 159 Vimtrup..reported that, in Amphibia, local contraction of capillaries always started at the site of one of the Rouget cells. 1961G. Bevelander Essent. Histol. (ed. 4) x. 106 According to some authors the tubule is clasped at intervals by Rouget's cells. These are branching cells which are said to be contractile and to cause the constriction of the capillaries. 1970T. S. & C. R. Leeson Histol. (ed. 2) xi. 217/1 Among the pericapillary elements, peculiar cells (Rouget cells) with long branching processes which surround the capillary wall have been described. Early studies indicated that these cells were contractile and were responsible for the contractility of capillaries. More recent work suggests that true capillaries in mammals do not possess Rouget cells and that capillary contractility is independent of them. |
