One of the following is associated with an erupted tooth:

The major component of dental plaque is:

One of the following does contribute to the formation of the upper lip:

The Hertwig epithelial root sheath of disintegrates:

Concerning cleft lips and cleft palates:

What is the outcome of repair?

What is the outcome of regeneration?

Growth factors and their receptors can be grouped into ‘superfamilies,’ based upon shared features of ?

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.?

Yamanaka’s factors were used to generating iPSc in 1st generation because:?

Periodontium which includes?

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

A protein that binds to DNA and regulates gene expression by promoting or suppressing transcription?

Mesenchymal stem cells have been confirmed able to differentiated into neuron cell with function?

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.?

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

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

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

The main reason for formation of scale is due to detraction of connective tissue.?

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

Why transcription factor C-Myc is no longer use for generating iPSc?

Why generation of iPSc is so attractive to scientist worldwide?

Growth factors and their receptors can be grouped into ‘families,’ based upon shared features of size and location, and into ‘superfamilies,’ based upon shared their functions.?

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

What is the hierarchy of induced pluripotent stem cells?

What are the criteria for achieving to generate iPSc?

What is the hierarchy of embryonic stem cells?

There are two major factors influence repair and regeneration?
