Stem cells are considered as a boon for mankind in the medical world. But the limited supply of stem cells has paused the progress on many fronts. Researchers working on embryonic like stem cells from adult donors. This process has involvement of huge number of genes which are like double edged swords as they also trigger cancer. A single gene which can produce billions of supercharged stem cells, by which body repair itself has been patented. Induced pluripotent stem (iPS) cell technology evolved by the rigours efforts of university of central florida(UCF) which minimizes the risk. This technology turns into magic wand and changes the landscape of regenerative medicine.
NANOG gene codes for nanog protein involved in the self renewal of embryonic stem cells. This is considered as a key factor for pluripotency of embryonic stem cells and gives potential to derive any type of cells (endoderm, ectoderm, mesoderm). Presence of more amounts of Nanog protein in the mouse embryonic stem cells caused self renewal but in the absence caused differentiation of embryonic stem cells into functionally different cells. This gives very important clue to the medical world. The literal understanding of this gene will lead into new avenue where patient own cells can be used for curing many degenerative diseases and sprouts the healing power hidden within the body.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
