Another term for the deglutition of food is:

First stage of deglutition is:

All of the following is a functional activity of the enamel organ, except:

The tooth in permanent dentition is the most susceptible to dental caries is:

All of the following does occur in the active phase of tooth eruption, except:

The occipital somite’s myotomes give rise to:

If the process of morphogenesis is disturbed:

Oral foci of Miller’s are seen in:

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

The lateral spread of dental caries is facilitated mostly by the:

Histological changes occurring during the eruptive phase:

Four basic qualities:

Cells responsible for repair and regeneration consist of?

Mesenchymal stem cells can be extract from many types of tissue, but the most commence one is bone marrow.?

Embryonic stem cells were banned for basic research practice because it is an unethical practice. Moreover, it cannot create patient-match specific cell line.?

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

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

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.?

What are the function of transcription factors?

How many protein structure were classified?

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

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

What is the biggest conflict of using induced pluri-potent stem cells?

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

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

Why embryonic stem cells were banned for basic research?

Stem cell hierarchy from top to bottom?

Growth factor responsible for repair and regeneration: TGF-b, Transforming growth factor b.?
