Stem Cells in Growth and Development of the Human Fetus
Phuc Van Pham
Stem cells are considered the origins of all organisms. In fact, all organisms are formed and developed from a single cell – the zygote, which is the product of oocyte fertilization by the sperm. This cell is referred to as a totipotent stem cell. Through the process of cell division, the totipotent stem cell produces all tissue types within an organism.
