Researchers have used human stem cells in the laboratory to mimic the earliest stage of human embryo growth yet. Multiple research groups have reported successful growth of balls of cells that ...

Researchers that study in vitro fertilization, human development and the diseases that may arise during that time, and miscarriages face a lot of challenges in investigating the biology underlying ...

The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

In a discovery that will revolutionize research into the causes of early miscarriage, infertility and the study of early human development - an international team of scientists led by Monash ...

Researchers have very limited opportunities to study the earliest stages of human development, but a groundbreaking discovery led by a team in Australia will now provide them with a valuable new model ...

The study of early human development has been hindered by technical difficulties and the limited availability of embryonic material for research. The blastocyst is a key developmental stage that ...

Scientists have discovered that they can generate induced blastoids, or iBlastoids, that emulate natural human blastoids. Because iBlastoids are built of reprogrammed skin cells, they represent ...

Live Action, a human rights non-profit, has released an animated video illustrating human development from conception up to ...

The creation of cellular structures similar to blastocysts has enabled KAUST scientists to build an in vitro model that mimics the earliest moments of human embryogenesis. A blastocyst is the first ...

To better understand the earliest stages of human growth, researchers can examine donated embryos or human embryonic stem cells, both of which are in limited supply, or address their questions with ...

New "models" of early human embryos that cannot grow into full human beings provoke ethical questions about whether they are human beings. One ethicist warns that research should be halted out of ...
