Reproduce
Definition:
(v. t.) To produce again.
(v. t.) To bring forward again; as, to reproduce a witness; to reproduce charges; to reproduce a play.
(v. t.) To cause to exist again.
(v. t.) To produce again, by generation or the like; to cause the existence of (something of the same class, kind, or nature as another thing); to generate or beget, as offspring; as, to reproduce a rose; some animals are reproduced by gemmation.
(v. t.) To make an image or other representation of; to portray; to cause to exist in the memory or imagination; to make a copy of; as, to reproduce a person's features in marble, or on canvas; to reproduce a design.
Example Sentences:

(3) In experiments performed to determine whether PtdIns(4,5)P2 hydrolysis induced by TRH may have been caused by the elevation of [Ca2+]i, the following results were obtained: the effect of TRH to decrease the level of PtdIns(4,5)P2 was not reproduced by the calcium ionophore A23187 or by membrane depolarization with 50 mM K+; the calcium antagonist TMB-8 did not inhibit the TRH-induced decrease in PtdIns(4,5)P2; and, most importantly, inhibition by EGTA of the elevation of [Ca2+]i did not inhibit the TRH-induced decrease in PtdIns(4,5)P2.
