Self-renewal and differential ability make stem cells as probable tools for regeneration, repair or replacement therapies in a diversity of disease conditions. Furthermore, due to its plasticity and tropism to gather in diverse lesions, stem cells can be used as a tool to carry therapeutic gene for repair or regeneration of affected tissues. Contingent of their sources, stem cells are broadly characterized into embryonic stem cells (ESCs) i.e. cells derived from the inner cell mass of the blastocyst, and adult stem cells i.e. cells isolated from the adult bone marrow, peripheral blood or from specific organs.
High-impact journals are those considered to be highly influential in their respective fields. 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.
