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

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

A,growth factor is a naturally occurring substance capable of stimulating cellular growth, proliferation, healing, and cellular differentiation. Usually it is a protein or a steroid hormone.?

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

Event during or following protein translation ?

One strategy to accomplish this goal is nuclear reprogramming, a technique that involves experimentally inducing a stable change in the nucleus of a mature cell that can then be maintained and replicated as the cell divides through mitosis. ?

Periodontium which includes?

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). ?

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.?

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

Why generation of iPSc is so attractive to scientist worldwide?

What are the function of transcription factors?

The inner cell mass cells have the potential to generate any cell type of the body, but after implantation, they are quickly depleted as they differentiate to other cell types with more limited developmental potential. ?

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

How many types of intra oral tissue?

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

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

When the first human iPSc were generated and published?
