title: The effect of exogenous nucleosides on postimplantation development of mouse embryos.
abstract: Exogenous nucleosides, either singly or in combination, do not enhance postimplantation development of mouse embryos in vitro, and adenosine, guanosine and thymidine are toxic to the embryos at high concentrations.
