00:04humans have long been able to create a human embryo via in vitro fertilization or combining
00:09egg and sperm in a test tube and then inserting those back into the mother for maturation but
00:13now in a scientific first researchers have created a synthetic human embryo without either of those
00:19two components this is professor jacob hannah of the wiseman institute of science in israel
00:24according to him the process of human embryo development is still very much a mystery as
00:29there are ethical limitations with regards to accessing and observing that material that's
00:33why he says he and his team endeavored to create a synthetic human embryo analog so they could better
00:37observe the cellular maturation process the research team used human stem cells that were donated years
00:42ago here's professor hannah to explain the process and what we do this time is we put them in a
00:48special
00:48media that takes them to really really early stages so we can see that they start cells start
00:54differentiating correctly migrating and sorting themselves into the correct structure and the
01:00farthest we could get is as day 14 in human embryo development many are now decrying ethical concerns
01:06with this type of research though hannah maintains they're not trying to make a human baby simply
01:10attempting to better understand the process and perhaps help us better treat issues that arise during pregnancy
