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.

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

Neurons

Placenta

Dental pulp

Adipose tissue.

Adult stem cells are summoned to replenish the dying cells and regenerate the damaged tissue.

True

False

Maybe
