The term totipotent describes the properties of an individual cell (not a group of cells) with the two meanings of this term roughly corresponding to the progressive restriction in potential cells exhibit during normal development.

2017年3月31日 · The main difference between totipotent and pluripotent is that totipotent stem cells are capable of differentiating into all types of body cells whereas pluripotent stem cells are capable of differentiating into any of the three germ layers of the embryo.

2024年1月24日 · Stem cells are characterized according to their degree of potency, which refers to their varying ability to differentiate into different cell types. Totipotent cells are the most potent of all stem cells, and defining them is important for …

2024年12月3日 · Totipotent stem cells are the most versatile stem cell type, because they are formed shortly after fertilization of an egg cell by a sperm cell. They can become all of the cells of the human body, as well as the cells of the embryo and developing fetus.

2024年10月22日 · The zygote formed when a sperm cell fertilises an egg cell is totipotent, as are the embryonic cells up to the 16-cell stage (morula) of human embryo development
