Research Performance in Stem Cell Science and Regenerative Medicine in Iran: A National Comprehensive Observation

Background: Accomplishments in stem cell science and tissue engineering have resulted in a remarkable revolution in the context of future medicine. However, a general insight over the progress of stem cell research in Iran is still lacking. A better understanding of current needs in this field is required to design a better national roadmap. Methods: In this study, we defined the geographical regions based on the significance of their contribution to stem cell research; then, using the Scopus database, we retrieved reports from Iran and other countries concerning stem cell science and regenerative medicine published from 1994 until the end of 2016. Results: A significant number of citations belong to North America (6 554 029 citations equal to 49% of the total citations) and Europe (4 425 465 citations equal to 33% of the total citations) and the rest of citations were related to Asia (2 423 352 citations equal to 18% of the total citations). East Asian (2 168 472 citations equal to 76% of the total citations related to Asia) documents were cited more than those from the Middle East (ME) (494 141 citations equal to 17% of the total citations related to Asia) and North and Central Asia (196 382 citations equal to 7% of the total citations related to Asia). Iran as a country in the ME attracted 17% of the total citations related to the Asian countries winning the second position in this regard. The overview of total number of citations showed a sharp increase and upward trend in citation numbers for all the Iranian institutes from 2007 that resulted in the expansion of stem cell science in all major cities of Iran such as Shiraz (8%), Mashhad (5%), Isfahan (5%) and Ahvaz (5%). H-index of Tehran University of Medical Science, which has the highest total citations and document numbers, is the highest among all Iranian research institutes. Citation per paper of Royan Institute (RI) is the highest among the top 10 Iranian institutes, by 13 citations per paper. Conclusion: Stem cell research in Iran is rapidly developing. Since 2007, the number of published documents in major research institutes increased; thus, there is necessity for analysis of the status of publications in this field and choosing a better direction based on needs. Furthermore, it is necessary to expand and organize international collaborations to enrich our research and benefit from different team experiences.
