In order to identify multi-potency stem cells, ones has to undergo cellar differentiation EXCLUDE?

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

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

Ethical issues associated with the production of ESCs do apply to iPSCs, which offer a controversial strategy to generate patient-specific stem cell lines.?

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.?

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

Who are/ is the pioneer of generating iPSc?

Activation, or promotion – increase the rate of gene transcription?

Growth factors and their receptors can be grouped into ‘families,’ based upon shared features of size and location, and into ‘superfamilies,’ based upon shared their functions.?

When the first mouse iPSc were generated and published?

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

Because ES cells can proliferate without limit and can contribute to any cell type, human ES cells offer an unprecedented access to tissues from the human body. ?

If the ICM, inner cell mass, is removed from its normal embryonic environment and cultured under appropriate conditions, the ICM-derived cells can ——————————————- indefinitely and still maintain the developmental potential to form any cell type of the body?

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

What is the biggest conflict of using embryonic stem cells?

iPSc were generated by:?

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

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

Chromatin immunoprecipitation (ChIP) is a type of immunoprecipitation experimental technique used to investigate the interaction between?

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

Transcription factor is a protein that controls the rate of transcription of genetic information from messenger RNA to DNA, by binding to a specific ribosomes.?
