9.Stem Cell and Cloning (Part-2) Flashcards
What is the definition of Totipotent Stem Cells?
Totipotent stem cells have the ability to be converted into any type of cell in the body.
What is the definition of Pluripotent Stem Cells?
Pluripotent stem cells convert into the majority of cells in the body.
What is the definition of Multipotent Stem Cells?
Multipotent stem cells have the capacity to be converted into a good number of cells.
What is the definition of Oligopotent Stem Cells?
Oligopotent stem cells can be converted into a few cells.
What is the definition of Unipotent Stem Cells?
Unipotent stem cells are converted into single cells.
What is the order of stem cells based on capacity?
The capacity of stem cells decreases from Totipotent stem cells to Unipotent stem cells.
What is the order of stem cells based on specialization?
The specialization of stem cells increases from Totipotent to Unipotent stem cells.
What is the definition of Embryonic Stem Cells?
Embryonic stem cells are found in the embryonic stage inside the mother’s womb and include Totipotent and Pluripotent stem cells.
What is the definition of Adult Stem Cells?
Adult stem cells are found in the adult human body and include Multipotent, Oligopotent, and Unipotent stem cells.
What are the characteristics of Totipotent Stem Cells?
~Totipotent stem cells can divide into any type of cells in the body.
~They are present in the early embryonic stage (1 week old).
~Totipotent stem cells are banned globally due to ethical and legal issues.
~For medical research, Totipotent stem cells can be obtained from embryos developed in the lab by IVF (In Vitro Fertilization).
What is the definition of Pluripotent Stem Cells?
Pluripotent stem cells are formed by the division of Totipotent stem cells and have the ability to give rise to the majority of cells and tissues in the body through division.
Why are Pluripotent Stem Cells considered medically important?
Pluripotent stem cells are the most important stem cells for medical applications, such as stem cell therapy and treatment.Pluripotent stem cells are the most important stem cells for medical applications, such as stem cell therapy and treatment.
Can a baby’s stem cells be used in blood relations other than the baby itself?
Yes, in some cases the stem cells of a baby can be used in blood relations such as parents and siblings, after matching the blood group and HLA (Human Leukocyte Antigen).
What are the different stages from which Pluripotent Stem Cells can be retrieved from the human body?
~Later embryonic stage (After 1 week): Retrieval from this stage is banned due to the potential harm it can cause to the womb.
~Miscarriage (within 12 weeks): Pluripotent stem cells can be retrieved from miscarriages for research purposes.
~Umbilical cord blood of the baby: Pluripotent stem cells can be retrieved from the umbilical cord blood and are used in stem cell therapy and treatment.
How long can Pluripotent Stem Cells from umbilical cord blood be stored?
Pluripotent stem cells from umbilical cord blood can be stored for up to two decades.
How are Pluripotent Stem Cells from umbilical cord blood preserved?
~The stem cells of umbilical cord blood are preserved in liquid nitrogen at a temperature of -196 degrees Celsius.
~This preservation process is known as cryopreservation.
