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

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

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. ?

Cells responsible for repair and regeneration consist of?

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

Retroviruses used to deliver the four transcription factors in the earliest studies is safe to generating iPSCs.?

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

What is the outcome of regeneration?

The process by which information from a gene is used in the synthesis of a functional gene product such as a protein?

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

What is the biggest conflict of using embryonic stem cells?

Who are/ is the pioneer of generating iPSc?

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

Morphology of mesenchymal stem cells ?

How many protein structure were classified?

iPSc were generated by:?

Transcription factors sometime is called ?

Mesenchymal stem cells can be extract from many types of tissue, but the most commence one is bone marrow.?

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

Periodontium which includes?

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

Why generation of iPSc is so attractive to scientist worldwide?
