1. A : Totipotent stem cells form when a fertilized egg first divides. 2. Totipotent stem cells can develop into a complete individual.3. Researchers have often called cells at this stage of development totipotent , Doerflinger said. 4. Totipotent cells are present in the morula up to the 16-cell stage.5. Q : What are totipotent stem cells? 6. The human development model is one which can be used to describe how totipotent cells arise. 7. The difference between totipotent , pluripotent and multipotent stem cells may grow less significant as research proceeds. 8. A : After a few days, totipotent stem cells form a blastocyst, a ball of cells. 9. Most distinct cell types arise from a single totipotent cell, called a zygote, that division ). 10. Approximately four days after fertilization and after several cycles of cell division, these totipotent cells begin to specialize.
