What are the 4 steps of responses of mucosa to damage?

Cytokines are a broad and loose category of long big proteins (~5–20 kDa) that are important in cell signalling.?

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

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

Growth factors are proteins that regulate many aspects of cellular function, including survival, proliferation, migration and differentiation.?

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

iPSc were generated by:?

Stem cell hierarchy from top to bottom?

Growth factors and their receptors can be grouped into ‘superfamilies,’ based upon shared features of ?

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

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

Transcription factors is a protein that control the rate of transcription of genetic information from?

How many types of intra oral tissue?

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

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

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

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

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

What is the hierarchy of mesenchymal stem cells?

When the first human iPSc were generated and published?

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

Some important human diseases are caused by the death or dysfunction of one or a few cell types, e.g., insulin-producing cells in diabetes or dopaminergic neurons in Parkinson’s disease. Therefore, understanding and using stem cells as tool to study this disease model provide a better understand this dysfunction of cell types.?
