Question

Stem cells have the ability to divide and produce unspecified cells. They can be developed into a required tissue because of their ability of .

Answer 1

Stem cells can be developed into a required tissue because of their ability to differentiate into any tissue. Stem cells generally have three basic properties:
1. They have the ability to divide and renew themselves for a long period of time.
2. Stem cells are unspecialized cells.
3. Stem cells can give rise to specialized cell types.
The process by which unspecialized stem cells become specialized is called differentiation. Differentiation involves many stages and at each stage the cells becomes more specialized.

Answer 2

Differentiation—The process whereby an unspecialized embryonic cell acquires the features of a specialized cell such as a heart, liver, or muscle cell.

I'm pretty sure this is it.
