Normal function of saliva:

A growth factor is a naturally occurring substance capable of stimulating cellular growth, proliferation, healing, and cellular differentiation.?

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

What is the biggest conflict of using induced pluri-potent stem cells?

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.?

Repression, or suppression – decrease the rate of gene transcription?

What is the outcome of repair?

Transcription factor sometimes is called sequence-specific DNA-binding factor.?

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

Who are/ is the pioneer of generating iPSc?

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.?

Mesenchymal stem cells is derived from bone marrow. So they can differentiate into hematopoietic cell line.?

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

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

Periodontium which includes?

What do Growth Factors Do?

The biggest concern of using iPSc as a regenerative tool is the possible of cancer provoke due to infection of transcription factors.?

Controlling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA?
