Adult skin cells that have been tweaked by scientists to behave as stem cells are known as__________________.
Mesenchymal stem cells
Hematopoietic stem cells
Induced pluripotent stem cells
Embryonic stem cells
Embryonic stem cells are derived from the blastocyst of human embryo.
True
False
Which of the following is true about totipotent cells?
They differentiate into specific cell types
They are altered to behave like embryonic stem cells
They have very high potency
They take part in the process of hematopoiesis
MSCs are genetically identical to the mother.
True
Maybe
False
What is difference between HSCs and MSCs?
HSCs differentiate into only blood cells; MSCs differentiate into cells other than the blood cells
HSCs differentiate into cells other than the blood cells; MSCs differentiate only into blood cells
Neither of them differentiate into any cells
Both the cells differentiate into blood as well as other types of cells.
Which one is false about Pluripotent stem cells?
They differentiate into cells from any of the three germ layers.
They give rise to the extra-embryonic cells.
Their potency rate is medium.
They are derived from the inner mass of the blastocyst.
What type of cells are found in adult stem cells?
Pluripotent
Multipotent
Totipotent
What is unique about stem cells?
They are unspecialised
They do not give rise to specific cells
They are found exclusively in the bone marrow
They are of only one type i.e. totipotent
Where are stem cells found?
Bone marrow
Neurons
Placenta
Dental pulp
Embryo
Nephrons
Islet cells
Adipose tissue.
Adult stem cells are summoned to replenish the dying cells and regenerate the damaged tissue.
True
False
Maybe
