Barcoding mouse embryos …

… and people are next.

Sounds pretty creepy, but it seems there’s some actual utility in the process to aid in vitro fertilization right now.

From the link:

Scientists from Spain’s Universitat Autònoma de Barcelona (UAB), along with colleagues from the Spanish National Research Council, have successfully developed an identification system in which mouse embryos and oocytes (egg cells) are physically tagged with microscopic silicon bar code labels. They expect to try it out on human embryos and oocytes soon.

The purpose of the system is to streamline in vitro fertilization and embryo transfer procedures. If egg cells and embryos can be quickly and easily identified, then things should run much smoother, and success rates should be higher.

The research, published online in Human Reproduction, represents a first step towards designing a direct labeling system of oocytes and embryos. The objective was to develop a system that minimizes risks when identifying female gametes and embryos during in vitro fertilization and embryo transfer procedures, to reduce the phases of the clinical process requiring control and supervision by two embryologists.
