Work flow of generating iPSc?

What are the function of transcription factors?

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

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.?

In the future, possible dentist can use dental pulp stem cells, 3rd mandibular molar, in cell bank due to their pluri-potent.?

The disadvantage of mesenchymal stem cells is that this stem cells are heterogenous in nature which hard to purify.?

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.?

What are the gold standard transcription factors using for generating iPSc?

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

When the first human iPSc were generated and published?

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

Yamanaka’s factors were chosen because they were known to be involved in the maintenance of pluripotency, which is the capability to generate all other cell types of the body.?

Mesenchymal stem cells are multi-potent stem cells which is able to differentiate to adult cell like?

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

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

What is the biggest conflict of using mesenchymal stem cells?

An undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.?

When the first mouse iPSc were generated and published?

What is the outcome of regeneration?

Initiation of caries by Streptococcus mutans is by the production of the:

Advanced bell stage of tooth development refers to:

Functions of the digestive system are:

Minor salivary glands are found throughout the mouth:

The apposition stage of tooth development begins:

One of the following is a component of tooth germ:

The Hertwig epithelial root sheath can’t be seen as a continuous layer in the developing root because:

For a bacterium to be seriously considered in the etiology of dental caries, it must:

Histological changes occurring during the eruptive phase:

The ectomesenchymal cell condensation just beneath the enamel organ is called:

A unilateral cleft lip is formed when:

All the statement below is true about the classification of taste, except:

The following induces the dental papilla cells to be differentiated into odontoblasts:

The Hertwig epithelial root sheath of disintegrates:

Concerning cleft lips and cleft palates:

Senile carious lesions are most commonly found exclusively on the following areas of the teeth:

All of the following is true of parotid glands, except:

Initiation of dental caries depends on:

Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm cell layer, and in turn give rise to A diverse cell lineage including:

Dental caries can be classified with respect to the site of the lesion:

The extrinsic muscles of the tongue are supplied by:

Median rhomboid glossitis is:

The muscles are derived from the first brachial arch:

All of the following are involved in the formation of a tooth except:

Streptococcus mutans is considered to be a principal etiologic agent of caries because it produces acid and it:

Concrescence is:

In the post-eruptive phase, a tooth undergoes primarily:

All of the following is the ectodermal in origin, except:

All of the following is a function of dental sac except:

Pharyngeal pouches:

The dental sac plays an important role in the formation of all of the following except:

Tongue begins to develop at:

The following are all derived from the stomodeal ectoderm such as:

A layer of cells that seems to be essential to enamel formation but do actually secrete the enamel except:

The following is component of the enamel organ except:

Actual eruptive movements of tooth occur mainly in a:

Taste buds contain:

Supernumerary roots occur mainly with:

The reduced enamel epithelium is derived from:

No basal lamina is found between the cells of the:
