In transcription an mRNA chain is generated, with both strands of the DNA double helix in the genome as a template.?

A protein that works with transcription factors to increase the rate of gene transcription?

The biggest different of outcome between repair and regeneration on tissue is tissue scaring.?

In our blood, there is a small amount of stem cells which are ready to be differentiate to any cell type under the control of growth factors.?

In the future, possible dentist can use dental pulp stem cells, 3rd mandibular molar, in cell bank due to their pluri-potent.?

iPSCs were reprogrammed to an embryonic stem cell-like state by introducing genes important for maintaining the essential properties of embryonic stem cells (ESCs). ?

Growth factors typically act as signalling molecules between cells. Examples are cytokines and hormones that bind to specific receptors on the cytoplasm of their target cells.?

Why transcription factors is the most import key to generate iPSc, cell reprogramming?

What is the outcome of repair?

A,growth factor is a naturally occurring substance capable of stimulating cellular growth, proliferation, healing, and cellular differentiation. Usually it is a protein or a steroid hormone.?

A specific sequence of DNA that a transcription factor binds to?

One strategy to accomplish this goal is nuclear reprogramming, a technique that involves experimentally inducing a stable change in the nucleus of a mature cell that can then be maintained and replicated as the cell divides through mitosis. ?
