Bone marrow stem cells are the stem cells found in the bone marrow, a spongy tissue in the bones. These stem cells develop into red blood cells, white blood cells and platelets. These are the most studied stem cells. These are used in bone marrow transplant for leukemia and hematopoietic diseases. These stem cells are also used for the treatment of diabetes, heart failure and other degenerative diseases. 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 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.
