11. Induced totipotent cells can be obtained by reprogramming somatic cells with somatic-cell nuclear transfer ( SCNT ). 12. A : There are three types _ totipotent , pluripotent and multipotent, each representing a different stage in development. 13. Thus they are totipotent cells equipped with regenerative powers that facilitate plant growth and production of new organs throughout lifetime. 14. At first it probably resembled today's sponges, which have totipotent cells that allow a disrupted organism to reassemble itself. 15. Human development begins when a sperm fertilizes an egg and the resulting fertilized egg creates a single totipotent cell, a zygote. 16. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. 17. Unlike animals, plant cells do not terminally differentiate, remaining totipotent with the ability to give rise to a new individual plant. 18. A cell that can differentiate into all cell types, including the placental tissue, is known as " totipotent ". 19. They were created by mixing cells from totipotent four cell blastocysts; although the cells never fused they worked together to form organs. 20. In a 1980 publication, Le Douarin detailed her process of inserting totipotent quail nerve cells into the neural primordium of a chick.
