Global tissue engineering trends. A scientometric and evolutive study.

Abstract

Tissue engineering is defined as a multidisciplinary scientific discipline with the main objective to develop artificial bioengineered living tissues in order to regenerate damaged or lost tissues. Since its appearance in 1988, tissue engineering has globally spreaded in order to improve current therapeutical approaches, entailing a revolution in clinical practice. The aim of this study is to analyze global research trends on tissue engineering publications in order to realize the scenario of tissue engineering research from 1991 to 2016 by using document retrieval from Web of Science database and bibliometric analysis. Document type, language, source title, authorship, countries and filiation centers and citation count were evaluated in 31,859 documents. Obtained results suggest a great multidisciplinary role of tissue engineering due to a wide spectrum —up to 51— of scientific research areas identified in the corpus of literature, being predominant technological disciplines as Material Sciences or Engineering, followed by biological and biomedical areas, as Cell Biology, Biotechnology or Biochemistry. Distribution of authorship, journals and countries revealed a clear imbalance in which a minority is responsible of a majority of documents. Such imbalance is notorious in authorship, where a 0.3% of authors are involved in the half of the whole production.
