Question

Quizplus · Accepted Answer

Stem cells from adult animals are not always totipotent but have the ability to divide and differentiate into a limited range of cell types when provided with specific external signals. This characteristic is known as multipotency or lineage-specific differentiation. Stem cells from adult animals can be found in various tissues, including bone marrow, and they can be isolated and used for therapeutic purposes. While it is possible to manipulate the expression of a few genes to induce differentiation of these cells into specific cell types, it requires careful control and optimization of various factors.
