WebJun 8, 2024 · Organs form from the germ layers through the differentiation: the process by which a less-specialized cell becomes a more-specialized cell type. This must occur many times as a zygote becomes a fully-developed organism. During differentiation, the embryonic stem cells express specific sets of genes which will determine their ultimate cell type. WebThe mesoderm is the middle layer of the three germ layers that develops during gastrulation in the very early development of the embryo of most animals.
