ABSTRACT:
Embryos and ova are manipulated at a work station that includes a microscope, a stage positioned below the objective the microscope on which an embryo- or ovum-containing sample is placed and micromanipulators and associated tools for operating on or otherwise manipulating the embryo or ovum. The specimen is illuminated with both bright-field illumination and dark-field illumination of contrasting hue to produce a composite image of the embryos or ova with the embryos or ova glowing with the dark-field hue against a bright background. The bright-field is transmitted through an aperture that is narrow to obtain a depth of field that is appropriate to three-dimensional manipulation.
