…first scientists to generate both chimeric and transgenic mammals. In 1996, she shared the inaugural March of Dimes Prize in Developmental Biology with Ralph L. Brinster for their work in developing transgenic mice. Much of her career was spent at Fox Chase Cancer Center in Philadelphia where, in 2002, she was appointed…
Fig. 2. Chimeric mouse. This mouse resulted from a blastocyst, which normally would produce a white mouse, that was injected with teratocarcinoma cells from a brown mouse. The dark stripes on the mouse represent the contribution of the foreign brown-type cells.
Fig. 5. Top panel. Recipient mouse testis that was injected with genetically modified spermatogonial stem cells containing a reporter transgene for Green Fluorescent Protein (GFP), which will fluoresce green. Bottom Panel. The testis will produce spermatozoa that transmitted the GFP transgene to offspring.
