This morning I received this email from the Penn Equine Assisted Reproduction Laboratory (PEARL) at U. Penn’s veterinary school, where I was trying this new ICSI technology on one of my older mares, CSA Baroness Lady. We have 2 cleaved embryos in culture for Baroness Lady x Dahjani Al Arab. Today is “Day 7” and 1 has developed to the blastocyst stage! Congratulations!! As a reminder, this embryo was frozen for future transfer into a recipient mare. We will continue to monitor developmental progress of the remaining 1 cleaved embryo in culture for another several days and I will provide a final update next week. How cool is that, the lay person that I am thought.
