Adult Stem Cells are undifferentiated cells found in the body. They have the capability to renew it and regenerate damaged tissues. These are also known as somatic stem cells as they are present all throughout the body. Adult Stem Cells are inactive cells in organisms where cell turnover is low. There is a very small number of Adult Stem Cells in the human body and once removed, the capacity to divide decreases. 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.
