When a tooth first erupts into the oral cavity, the attachment epithelial cuff of epithelium derived from:

iPSCs were reprogrammed to an embryonic stem cell-like state by introducing genes important for maintaining the essential properties of embryonic stem cells (ESCs). ?

The process by which information from a gene is used in the synthesis of a functional gene product such as a protein?

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

Event during or following protein translation ?

Embryonic stem cells are derived from embryos at a developmental stage before the time that implantation would normally occur in the uterus. Normally, it takes about 10 days.?

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

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

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

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

How many protein structure were classified?

Four transcription factors (Oct4, Sox2, Klf4, and c-Myc) sometimes is called Yamanaka’s factors.?

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. ?

iPSc provided unlimited supplies of ________ cells could be used to generate transplants without the risk of immune rejection.?

What is the hierarchy of embryonic stem cells?

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

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

Embryonic stem cells are derived from embryos at a developmental stage before the time that implantation would normally occur in?

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