Concerning teratogens and their effect on fetal development:

The cap stage occurs between the:

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

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

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

What is the hierarchy of induced pluripotent stem cells?

What is Yamanaka’s factors?

One strategy to accomplish this goal is nuclear reprogramming, a technique that involves experimentally inducing a stable change in the nucleus of a mature cell that can then be maintained and replicated as the cell divides through mitosis. ?

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

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

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

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

Stem cell hierarchy from top to bottom?

When the first mouse iPSc were generated and published?

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. ?
