To observe the first processes that shape a developing animal, Jesse and his team at the Max Planck Institute for Molecular Genetics in Berlin, Grew parts of mouse embryos in Petri dishes. They included mouse stem cells in a gel-like culture medium with properties analogous. To those of the so-called extracellular matrix (a gelatinous substance, Served to support and guide the stem cells, And allowed Embryos Petri dish them to develop over a period of up to five days, In the same way as occurs during the natural growth of the embryo in the uterine mucosa. The image shows embryo structures at different.
“MOUSE EMBRYONIC STEM CELLS SELF-ORGANIZE INTO
How a neural tube gradually extends from which the spinal cord later arises and, On the other, Cartilage and muscles. Precursor structures of internal organs also appear, Such as the intestine. Some parts have undergone abnormal development as a Rental Service business email list result of chemical. These processes are often difficult to observe in mammals. This is because their embryos are hardly accessible once they have Embryos Petri dish implanted in the uterus. Development in cell culture and to investigate the biochemical and genetic signals that control it.
