The most advanced lab-made human embryo models look like the real thing — they resemble, though don't perfectly replicate, natural embryos about 14 days into development. These lab-made embryo models ...

Bangkok — Scientists have developed human embryo-like structures without using sperm, an egg or fertilization, offering hope for research on miscarriage and birth defects but also raising fresh ...
