Scientists Create Living Entities In The Lab That Closely Resemble Human Embryos By
at 9:01 am NPR
For decades, science has been trying to unlock the mysteries of how a single cell becomes a fully formed human being and what goes wrong to cause genetic diseases, miscarriages and infertility.
Now, scientists have created living entities in their labs that resemble human embryos; the results of two new experiments are the most complete such model embryos developed to date.

Researchers re-create key human embryo stage in lab
Mar. 17, 2021 , 12:25 PM
A human embryo at the blastocyst stage is smaller than the tip of a ballpoint pen and may contain fewer than 100 cells, but this developmental waypoint has long puzzled and vexed biologists and physicians. Many miscarriages occur during this stage, for example, and a blastocyst can also split to create twins. Now, multiple research groups have found ways to mimic blastocysts, coaxing lab-grown human cells to form clusters that closely resemble the true thing.

Scientists Create Human Pre-Embryo for Research
By Dennis Thompson

WEDNESDAY, March 17, 2021 (HealthDay News) Research into miscarriages, infertility and birth defects is now primed to undergo revolutionary advances, thanks to the creation in the lab of an early stage of human embryos by two separate international teams of scientists.
Both teams were able to use human cells to create artificial blastocysts, an early stage of conception that occurs a few days after egg fertilization but prior to the implantation and development of an embryo in the uterus.
Until now, research into human blastocysts relied on embryo donations from in vitro fertilization (IVF) procedures, which were scarce and difficult to obtain.
