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

Growth factor responsible for repair and regeneration: TGF-b, Transforming growth factor b.?

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 factor responsible for repair and regeneration: KGF, Keratinocyte growth factor?

Why generation of iPSc is so attractive to scientist worldwide?

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

Cells responsible for repair and regeneration consist of?

Periodontium which includes?

Four transcription factors (Oct4, Sox2, Klf4, and c-Myc) sometimes is called Yamanaka’s factors.?

Yamanaka’s factors were chosen because they were known to be involved in the maintenance of pluripotency, which is the capability to generate all other cell types of the body.?

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.?

Growth factors and their receptors can be grouped into ‘families,’ based upon shared features of size and location, and into ‘superfamilies,’ based upon shared their functions.?

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

Protein synthesis consist of 2 steps. What are they, and where do they take place?

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. ?

Who are/ is the pioneer of generating iPSc?

The inner cell mass cells have the potential to generate any cell type of the body, but after implantation, they are quickly depleted as they differentiate to other cell types with more limited developmental potential. ?

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

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

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

In order to identify multi-potency stem cells, ones has to undergo cellar differentiation EXCLUDE?
