1870Ray Lankester in Ann. Nat. Hist. VI. 40 The right ventricle of the bird's heart is not homogenous with the right ventricle of the mammal's heart, nor the left with the left; but the two cavities in each case are homoplastic. 1872Darwin Orig. Spec. (ed. 6) xiv. 386 Homoplastic structures are the same with those which I have classed..as analogous modifications or resemblances.
2. Med. and Biol. Of transplantation: involving the transfer of tissue from one individual to another of the same species. Of transplanted tissue: obtained from another individual of the same species as the recipient.
[1889L. Ollier in Arch. de Physiol. normale et path. I. 168 Nous divisons les greffes en trois catégories: Les greffes autoplastiques... Les greffes homoplastiques, c'est-à-dire empruntées à un autre individu, mais à un sujet de la même espèce. Les greffes hétéroplastiques.] 1909Jrnl. Med. Res. XXI. 320 He [sc. Carrel] also distinguishes an autoplastic transplantation, when the segment is taken from the same animal; a homoplastic, when the segment is taken from another animal of the same species; and a heteroplastic, when the segment is taken from an animal of another species. 1912Ann. Surg. LVI. 381 Autoplastic bony pieces are in respect to regeneration much to be preferred to homoplastic. 1935Jrnl. Amer. Med. Assoc. 8 June 2076/1 These homoplastic grafts all sloughed, while autoplastic grafts were highly successful on the same patient. 1958Immunology I. 1 The homoplastic transplantation of the cortex of the adrenal gland in mice.
So homoˈplastically adv., between individuals of the same species; ˈhomoplasty, homoplastic transplantation, homotransplantation.
1912Ann. Surg. LVI. 378 The best material for free bony grafts is living, periosteum covered bone, if possible from the same individual himself (autoplasy [sic]). Or in case this is impossible, from another individual (homoplasty). 1923H. Neuhof Transplantation of Tissues ii. 31 The results have seemed to indicate that blood relationship has a bearing on the success of homoplasty. 1926Jrnl. Exper. Zool. XLV. 52 Fore-limb buds of R. palustris tadpoles were transplanted homoplastically beneath the integument of the back. 1929Ann. Surg. XC. 929 The lower the organism in the phylogenetic scale, the better the results obtained with homoplasty. 1942Univ. Calif. Publ. Zoöl. LI. 43 Gastrular anlagen were implanted homoplastically into tadpoles. |
