Control genes impede certain genes from expressing themselves and allow others to express themselves/ Thus a liver cell will have basically the same genome as a neuron, but will not express axon development and the neuron will not express bile development.
The ovaries are the glands that produce the egg cells. In humans, women are only born with a finite number of eggs which means they are only fertile for a certain amount of time.
No. Germ cells are needed to produce sperm. Sertoli cells only aid in the process.
They can only produce cells that are like themselves.
they are unipotent

Only adult stem cells produce progenitor cells because they multiply though the process of cell division and therefore produce progenitor cells.

Stem cells. that is why they are needed for research

No, Because chemicals are not living things...only living things will produce cells.
