Epistemological presuppositions include supposition affairs that are in beyond theoretical and practical activities, more or less consciously or unconsciously, regardless that scholars and researchers are aware or unaware of results; they are even assumed crucial. The origin of many differences of opinions, critics and problems that exist nowadays about use of Scientometrics methods, indices, and techniques in evaluating scientific activities and caused hesitation on theoretical and practical usage, originated from disagreement about basic Epistemological presuppositions. Therefore, in order to create more consensus among scholars and pay comprehensive attention to various dimensions of scientific evaluation - through identification and questioning presuppositions must revisen and provide background in order to analyse fundamental presuppositions. This work will lead to better understanding of current situation in this domain and will shed light on its real situation. On the other hand, strengthening Scientometrics' theoretical and practical basis need architecture and reconstruction of its basis on reliable presuppositions. Therefore, analysis of Epistemological presuppositions of Scientometrics would provide stronger (more consolidated) basis for it and would facilitate theorizing and even operation of izing research results. In this direction, this article for the first time has considered such a relatively comprehensive identification, classification and analysis of epistemological presuppositions of Scientometrics.

Introduction: For new scientific field to achieve more coherent position, it needs scientometric analysis more than other fields. This study aims to use citation analysis and scientific mapping of Iranian researchers' publications in stem cell indexed in science citation database up to 2015. Methods: This is an applied descriptive study using scientific mapping method. The population of this study is all types of Iranian researchers' publications in stem cell (2317 records) indexed in science citation database up to 2015. The data have been collected by observing the science citation index website and transcribing in to plain text in order to analyze it with HistCite software. Results: The results showed that Soleimani with 232 records (10 percent) achieved the first place in author's ranking. In universities ranking Tehran University of medical sciences was the first, which published 566 records (24. 5 percent) in the field of stem cell. This university also achieved high global and local citation score among the universities and institutions in Iran. The scientific publication growth procedure of this field increased up to 2014 but it had a little bit decrease from 2014 to 2015. The type of 1762 records (76 percent) of stem cell publication was article. The scientific map of stem cell based on both global and local citation score had two important clusters. Conclusion: The most important and cited articles on stem cell clusters have focused on the role of this field in treatments and pathogens diagnosis. According to the Tehran University of medical sciences top rank in this field, the scientific cooperation between the scientists and students of this university and the other universities and institutions is improving the scientific level of stem cell in Iran.
