Image 4A. Mouse sperm detail.
Image 4B. Mouse oocyte In Vitro Fertilization (IVF).
The vast majority of these
sperm will disappear when we isolate the oocyte for culture.
Only one will reach the goal.
Foto 5. Pig oocytes undergoing microinjection.
Note the high lipid content which obscures the cytoplasm
and hinders the observation of the cytoplasmic content.
Foto 6. Set of pig embryos in a microinjection experiment with CrispR-Cas9, after 5 days of culture.
Different embryos can be observed at the blastocyst stage, some of them early (yellow arrows),
others expanding (red arrows) and even emerging from the zona pellucida
(time prior to implantation, blue arrow).
