Article Synopsis
- Scientists are studying how human embryos develop before they implant in the womb and how stem cells from those embryos work, but there's still a lot to learn.
- Research shows that early embryo cells and stem cells from embryos don’t differ much, hinting that they might follow a new path in development.
- By creating a special gene network, researchers identified important genes that help understand the development of embryos and how stem cells survive and grow outside the body.
Objective: Compare the efficiency of two vitrification methods for single-blastomere cryopreservation with mouse or human embryos.
Design: Experimental prospective controlled study.
Setting: Research center.
Purpose: To analyze the results of our transferred embryos, especially those that "changed" their blastomere nuclearity from Multinucleated (MN) to Mono-nucleated during development.
Methods: Pregnancies where at least one MN embryo was transferred were retrospectively evaluated and categorized in order to record and follow-up on the ones that were implanted. Embryos were classified as normal (when all blastomeres were mono-nucleated on day one and two of development), corrected (multinucleated embryos on day one that became mono-nucleated on day two) and non-corrected (multinucleated either on day one, on day two or both days).
