, and when.
To their surprise, they found that almost from the very beginning some of the handful of cells had different sets of active genes.
An embryo's fate -- whether it would develop normally or not -- seemed determined in many cases from the moment of conception and relied heavily on the mother's egg cell, they found.
Embryos most likely to form a ball of cells called a blastocyst developed at a certain, measurable rate, they found.

"Blastocyst formation is a critical time point in human embryo development and provides more objective criteria for selecting which embryo(s) to transfer," Lissa Goldenstein

"For years, researchers have searched for ways to predict the embryos most likely to reach the blastocyst stage in order to enable earlier transfer and ultimately improve live birth rates for in vitro fertilization procedures."
The company estimates that there are 500 clinics in the United States providing in vitro fertilization or IVF services, with combined annual revenues of nearly $2 billion.

Researchers using a microscope and time-lapse photography believe they have developed a method for predicting which test-tube embryos are the most likely to develop properly
christian louboutin 2011 , and are licensing development of a commercial test.
Their findings, published in the journal Nature Biotechnology, also provide some new insights into the development of days-old embryos, such as how babies inherit some genes from the mother and some from the father.
They said the new test could help fertility clinics pick the best embryo to implant in the womb.
This would save mothers from having several treatments and help improve on the current method of implanting multiple embryos to try to get one pregn
