“Our model platform captures a specific snapshot of human development about which we know perhaps the least,” senior author Berna Sozen, assistant professor of Developmental Stem Cell Biology ...

The Need for Models of Human Development . ... Not only does this model give access into the human gastrulation window, but will also allow for a greater quantity of research.

Researchers hope these model embryos will shed light on the “black box” of human development, the period following 14 days after fertilization, which is the agreed limit for scientists to grow ...

We stand at a pivotal moment in our human development journey. For three decades, the Human Development Index (HDI) demonstrated a consistent increase in development progress and a decrease in ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that ...

A new model of tiny human ovary organoids, or ovaroids, has been developed from stem cells, according to research presented at the first Joint Congress between the European Society of Paediatric ...

Early human development is still a black box due to ethical and technical constraints, but our new model gives some visibility during this critical time, without needing to use human embryos.
