One of many flattened branching cells found around capillary blood vessels.
1925Amer. Jrnl. Anat. XXXV. 257 The ‘pericytes’ of mammals which Zimmerman has described. 1928Anatomical Rec. XXXIX. 45 The designations Rouget cells, adventitial cells, and pericytes are used indiscriminately on the assumption that they connote the same structures. 1965Ham & Leeson Histol. (ed. 5) xxii. 592 Opinion soon changed, and it was generally conceded that such cells as could be seen just outside the endothelium of the capillaries and the venules of most of the bodies of mammals were not contractile. Moreover, the noncontractile cells in this location came to be known by the terms of perivascular cells or pericytes. 1976W. J. Cliff Blood Vessels iv. 68 Pericytes are non-contractile cells which have well-developed phagocytic powers. Ibid. 71 Pericytes have primarily a mechanical supporting function within the walls of minute blood vessels. |
