¹ Rank was assigned by computing the average score of all the nouns present in the abstract and title of an article, and comparing this score with that of other articles in the merged list of 162,832 references. The merged set was constructed from 81,416 references randomly selected from MEDLINE combined with 81,416 references that are annotated with the MeSH term stem cells or one of its children in the MeSH hierarchy.
