totipotent การใช้

• A : Totipotent stem cells form when a fertilized egg first divides.
• Totipotent stem cells can develop into a complete individual.
• Researchers have often called cells at this stage of development totipotent, Doerflinger said.
• Totipotent cells are present in the morula up to the 16-cell stage.
• Q : What are totipotent stem cells?
• The human development model is one which can be used to describe how totipotent cells arise.
• The difference between totipotent, pluripotent and multipotent stem cells may grow less significant as research proceeds.
• A : After a few days, totipotent stem cells form a blastocyst, a ball of cells.
• Most distinct cell types arise from a single totipotent cell, called a zygote, that division ).
• Approximately four days after fertilization and after several cycles of cell division, these totipotent cells begin to specialize.
• Induced totipotent cells can be obtained by reprogramming somatic cells with somatic-cell nuclear transfer ( SCNT ).
• A : There are three types _ totipotent, pluripotent and multipotent, each representing a different stage in development.
• Thus they are totipotent cells equipped with regenerative powers that facilitate plant growth and production of new organs throughout lifetime.
• At first it probably resembled today's sponges, which have totipotent cells that allow a disrupted organism to reassemble itself.
• Human development begins when a sperm fertilizes an egg and the resulting fertilized egg creates a single totipotent cell, a zygote.
• During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells.
• Unlike animals, plant cells do not terminally differentiate, remaining totipotent with the ability to give rise to a new individual plant.
• A cell that can differentiate into all cell types, including the placental tissue, is known as " totipotent ".
• They were created by mixing cells from totipotent four cell blastocysts; although the cells never fused they worked together to form organs.
• In a 1980 publication, Le Douarin detailed her process of inserting totipotent quail nerve cells into the neural primordium of a chick.
