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. ?

iPSc were generated by:?

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.?

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

All four factors are absolutely necessary. In particular, the gene c-Myc is known to promote tumor growth in some cases, which would not affect iPSC usefulness in transplantation therapies. ?

Stem cell hierarchy from top to bottom?

Why generation of iPSc is so attractive to scientist worldwide?

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

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

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. ?

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

What is the biggest conflict of using embryonic stem cells?

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

Transcription factors sometime is called ?

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

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

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