Chemico-parasitic theory of dental caries is proposed by:

The dental lamina is induced to proliferate into a tooth bud by the:

First branchial arch is supplied by:

Odontogenesis of the primary dentition begins between:

The function of the inner enamel epithelium is:

If the process of morphogenesis is disturbed:

The following organisms is found in deep carious lesions rather than in incipient lesions is:

Pure mucous salivary gland is:

Taste bud is:

The bud stage of tooth development occurs at:

During the pre-eruptive phase of tooth eruption:

Second stage of deglutition is:

Cavity formation in a tooth, due to dental caries is due to:

The cell rests of Malassez are derivatives of:

An oblique facial cleft is the result of:

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

After fertilization of ovum series of cell division give rise to an egg cell mass called:

Advanced bell stage of tooth development refers to:

All of the following is part of the tooth germ except:

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.?

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). ?

All four factors are absolutely necessary. In particular, the gene c-Myc is known to promote tumor growth in some cases, which would not affect iPSC usefulness in transplantation therapies. ?

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.?

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

Morphology of mesenchymal stem cells ?

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

Who are/ is the pioneer of generating iPSc?

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

Because ES cells can proliferate without limit and can contribute to any cell type, human ES cells offer an unprecedented access to tissues from the human body. ?

Growth factor responsible for repair and regeneration: VEGF, Vascular endothelial growth factor?

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

iPSc were generated by:?

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

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

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

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

Upon introduction of reprogramming factors, cells begin to form colonies that resemble pluripotent stem cells, which can be isolated based on their:?

What are the function of transcription factors?

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