the fetus

The researchers used protein staining techniques to reveal the identity of the cells in the organoids they created. In the picture you can see four organoids of the central nervous system in the fetus, where in purple are proteins associated with the development of the front and middle brain, in green - the hindbrain, and in red - the center of the spinal cord

from the brain to the tail

Researchers from the University of Michigan and the Weizmann Institute of Science have for the first time developed a central nervous system on a chip that faithfully simulates that of the human fetus - from the end of the spinal cord to the forebrain
An artificial model of a human embryo in a developmental stage corresponding to day 12. The upper elliptical structure is the part that will become an embryo including the amniotic sac above it; The lower structure is the yolk sac. The interface between the two structures is an essential element for embryonic development in humans. Both parts are surrounded by a layer of cells which will become the placenta
