Deglutition problem can lead to:

By the 6th week of tooth development, the oral epithelium is:

The muscles of mastication are derived from:

The down growth of an epithelial thickening buccal to the dental lamina is known as:

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

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

During tooth eruption into the oral cavity, what happens to the epithelial covering of the enamel:

In human’s fertilization normally occurs in:

Hertwig’s root sheath consists of:

The function of the inner enamel epithelium is:

Widely accepted theory of dental caries is:

The Hertwing’s epithelial root sheath is composed of:

Palatal processes of the maxilla are derived from:

What is the hierarchy of embryonic stem cells?

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

Cytokines are a broad and loose category of long big proteins (~5–20 kDa) that are important in cell signalling.?

In our blood, there is a small amount of stem cells which are ready to be differentiate to any cell type under the control of growth factors.?

Transcription factor sometimes is called sequence-specific DNA-binding factor.?

Stem cell hierarchy from top to bottom?

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. ?

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. ?

Why embryonic stem cells were banned for basic research?

What is the outcome of repair?

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.?

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