Caption: Fluorescent microscopy of transgenic rhesus macaque monkey embryos being studied by professor Thaddeus Golos, one of which was injected with a vector expressing the green fluorescent protein reporter gene. The left panel is brightfield microscopy, the middle panel is under fluorescent illumination and the right panel is the two images overlaid. (Used with permission by UW-Madison.)

Caption: Life cycle illustration of transgenic rhesus macaque monkey embryo research being done by professor Thaddeus Golos, including rhesus preimplantation embryonic development, placental development, and mother with infant. Clockwise from upper left is:

1. A fertilized rhesus macaque embryo.
2. Early cleavage stage embryo.
3. Morula stage embryo where cells on the outside of the embryo are committing themselves to become the placenta.
4. Blastocyst stage embryo. The embryo was was injected with the gene-caarrying vector at this stage.
5. A later blastocyst-stage embryo.
6. A cross section of the placenta showing the fetal and maternal sides.
7. The successful outcome of pregnancy, mother rhesus macaque and infant.
