What is the biggest conflict of using mesenchymal stem cells?

What do Growth Factors Do?

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

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. ?

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

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

Event during or following protein translation ?

The biggest concern of using iPSc as a regenerative tool is the possible of cancer provoke due to infection of transcription factors.?

Mesenchymal stem cells is derived from bone marrow. So they can differentiate into hematopoietic cell line.?

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. ?

ES will support clinical research on the differentiation and function of human tissues and provide material for testing that may improve the safety and efficacy of human drugs ?

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

The first differentiation event in humans occurs at approximately —— days of development, when an outer layer of cells committed to becoming part of the placenta (the trophectoderm) separates from the inner cell mass (ICM). ?

Cre-Lox recombination is a site-specific recombinase technology, used to carry out deletions, insertions, translocations and inversions at specific sites?

Why generation of iPSc is so attractive to scientist worldwide?

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

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

Work flow of generating iPSc?
