Ova
Definition:
(n. pl.) See Ovum.
(pl. ) of Ovum
Example Sentences:
(1) Since 1987, it has become possible to obtain immature ova from the living animal and to let them mature, fertilize and develop into embryos capable of transplantation outside the body.
(2) We previously found that transfected TNP-specific B cells undergo both Ca2+ signaling and desensitization upon interaction with the thymus-dependent Ag TNP-OVA.
(3) These observations indicated that OVA-binding B cells in the peripheral blood are already committed to producing IgM antibody and probably are the precursors of antibody-forming cells of the IgG or IgE class.
(4) Synchronously transferred ova showed no such developmental precocity.
