An initial topic search of the term \u201cregenerative medicine\u201d returned 10,553 records published between 2000 and 2015 in the Web of Science (WoS). We first ranked these records with usage count and times cited, respectively, and selected the top 2,000 records for each. We then performed a co-citation analysis in order to obtain the citing papers of the co-citation clusters as the research fronts. Finally, we compared the average publication year of the citing papers as well as the mean cited year of the co-citation clusters.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jdis-2017-0005_s_007_w2aab2b8b6b1b7b1aab1c15b3Aa\">\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>The citing articles detected by usage count tend to be published more recently compared with times cited within the same research front. Moreover, research fronts detected by usage count tend to be within the last two years, which presents a higher immediacy and real-time feature compared to times cited. There is approximately a three-year time span among the mean cited years (known as \u201cintellectual base\u201d) of all clusters generated by usage count and this figure is about four years in the network of times cited. In comparison to times cited, usage count is a dynamic and instant indicator.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jdis-2017-0005_s_008_w2aab2b8b6b1b7b1aab1c15b4Aa\">\n                    <jats:title>Research limitations<\/jats:title>\n                    <jats:p>We are trying to find the cutting-edge research fronts, but those generated based on co-citations may refer to the hot research fronts.
