Stem cell hierarchy from top to bottom?

There are two major factors influence repair and regeneration?

Periodontium which includes?

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

Growth factor responsible for repair and regeneration: EGF, Epithermal growth factor?

Event during or following protein translation ?

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

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

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.?

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

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. ?

In transcription an mRNA chain is generated, with both strands of the DNA double helix in the genome as a template.?

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

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

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