What are the function of transcription factors?

Why transcription factor C-Myc is no longer use for generating iPSc?

Transcription factors sometime is called ?

Embryonic stem cells were banned for basic research practice because it is an unethical practice. Moreover, it cannot create patient-match specific cell line.?

iPSc provided unlimited supplies of ________ cells could be used to generate transplants without the risk of immune rejection.?

What are the gold standard transcription factors using for generating iPSc?

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. ?

Growth factor is sometimes used interchangeably among scientists with the term cytokine.?

The process of making messenger RNA (mRNA) from a DNA template by RNA polymerase?

Growth factor responsible for repair and regeneration: PDGF, Platelet derived growth factor?

Mesenchymal stem cells are multi-potent stem cells which is able to differentiate to adult cell like?

Cre-Lox recombination is a site-specific recombinase technology, used to carry out deletions, insertions, translocations and inversions at specific sites?

Mesenchymal stem cells can be extracted from marrow and non-marrow.?

How many types of intra oral tissue?

The process by which information from a gene is used in the synthesis of a functional gene product such as a protein?

Upon introduction of reprogramming factors, cells begin to form colonies that resemble pluripotent stem cells, which can be isolated based on their:?

Cells responsible for repair and regeneration consist of?

Who are/ is the pioneer of generating iPSc?

Activation, or promotion – increase the rate of gene transcription?

Transcription can be divided into 3 stages: initiation, elongation, and termination, each regulated by a large number of proteins such as transcription factors?

The main reason for formation of scale is due to detraction of connective tissue.?

If the ICM, inner cell mass, is removed from its normal embryonic environment and cultured under appropriate conditions, the ICM-derived cells can ——————————————- indefinitely and still maintain the developmental potential to form any cell type of the body?
