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

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. ?

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

What is the hierarchy of induced pluripotent stem cells?

What is the biggest conflict of using embryonic stem cells?

Growth factor responsible for repair and regeneration: VEGF, Vascular endothelial growth factor?

What is the hierarchy of embryonic stem cells?

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: EGF, Epithermal growth factor?

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

Why generation of iPSc is so attractive to scientist worldwide?

Event during or following protein translation ?

A specific sequence of DNA that a transcription factor binds to?

Work flow of generating iPSc?

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

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

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

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. ?
