Fluorescent microscopy image of the new cells and placenta progenitor stem cells. The new cells are marked in red, and cells corresponding to placental stem cells are shown in green. The DNA of each cell is shown in blue. Credit: Amitesh Panda Professor Vincent Pasque and his colleagues athave used stem cells to create a new kind of human cell in the lab. The new cells closely mirror their natural counterparts in early human embryos.
Vincent Pasque’s team at KU Leuven has developed the first model for a specific type of human embryo cells, extraembryonic mesoderm cells. Professor Pasque: “These cells generate the first blood in an embryo, help to attach the embryo to the future placenta, and play a role in forming the primitive umbilical cord. In humans, this type of cell appears at an earlier developmental stage than in mouse embryos, and there might be other important differences between species.
