In genetic terms, stem cells are cells in the embryo that are not specialized. After fertilization, there are two types of cells in the embryo. Specialized cells:These are the cells modified with clearly defined instructions or tasks.They are the cells that go on to define set things like taste, hearing, sex and the like. As they divide and grow, they do NOT change into any kind of cell.hese are cells in the embryo (just after fertilization), usually obtained from human embryos that are a few days old and are left over from human fertility treatments.
