Nacre
Definition:
(n.) A pearly substance which lines the interior of many shells, and is most perfect in the mother-of-pearl. [Written also nacker and naker.] See Pearl, and Mother-of-pearl.
Example Sentences:
(1) When nacreous shell produced by the marine oyster Pinctada maxima, used as a biomaterial in oral surgery, is implanted in human bone, new bone formation occurs, resulting in a tight welding of the bone to the nacre [16].
(2) Dilute suspensions of normal erythrocytes exhibit a pearl-like sheen (nacre) when subjected to flow.
(3) Nacre implanted in vivo in bone is osteogenic suggesting that it may possess factor(s) which stimulate bone formation.
