The different stages of human development. The fetal stage of human development begins around 8 weeks after fertilization — when the embryo has developed its basic form — and lasts until birth. It’s a transformation unlike any other: from a 1-inch-long, bean-shaped body to a fully formed newborn, 20 inches (50 cm) long and weighing around 7.5 pounds (3.4 kg). By the end of the first trimester, most major organs are in place. The heart has been beating since about week 6, but now it’s pumping blo

A team of researchers from Cambridge University and California Institute of Technology say they have created the world’s first synthetic human embryo without an egg and sperm. The embryo-like structures were made from stem cells and are at the earliest stages of fetal development, according to scientists. However, these experiments could one day be groundbreaking in providing new information on genetic diseases or the causes of miscarriages. #Science | Cheddar Gadgets

Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early stages of embryonic development https://reut.rs/45WUG6x | Reuters
