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

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.?

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

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

Growth factor responsible for repair and regeneration: FGF, fibroblast growth factor.?

Morphology of mesenchymal stem cells ?

Cells responsible for repair and regeneration consist of?

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. ?

What is the biggest conflict of using embryonic stem cells?

What is the outcome of regeneration?

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

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

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

Upon introduction of reprogramming factors, cells begin to form colonies that resemble pluripotent stem cells, which can be isolated based on their:?

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. ?
