Lab-grown Humans:
Scientists created a complete human-like embryo model without using a sperm or egg.
The synthetic embryo was grown using stem cells, and it closely resembled a typical human embryo in structure and development for up to 14 days.
The researchers used pluripotent stem cells, known for their ability to mature into various cell types. They took these pluripotent stem cells and converted them into their "naïve" state, which has the potential to develop into any cell within the body, including those crucial in early human development. To generate lab-made embryos, the researchers mixed three groups of stem cells: one group naturally grew to form the embryo, while the other two groups were manipulated to become supportive structures like the placenta and yolk sac. Although most clusters of stem cells failed to progress, approximately one percent advanced into structures resembling embryos. These stem cell-based embryo-like structures or SEMS, grew and organized themselves, demonstrating the necessary components of a 14-day-old embryo in the womb. The researchers even conducted pregnancy tests on the SEMS, which returned positive results. The study will enhance our understanding of early pregnancy stages, offering insights into the fine architecture of embryonic development.
