The biggest different of outcome between repair and regeneration on tissue is tissue scaring.?

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

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

Why transcription factors is the most import key to generate iPSc, cell reprogramming?

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

Mesenchymal stem cells can be extracted from marrow and non-marrow.?

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

In our blood, there is a small amount of stem cells which are ready to be differentiate to any cell type under the control of growth factors.?

Growth factor responsible for repair and regeneration: PDGF, Platelet derived growth factor?

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. ?
