A bibliometric study to assess bioprinting evolution

Abstract

Bioprinting as a tissue engineering tool is one of the most promising technologies for overcoming organ shortage. However, the spread of populist articles among on this technology could potentially lead public opinion to idealize its readiness. This bibliometric study aimed to trace the evolution of bioprinting literature over the past decade (i.e., 2000 to 2015) using the SCI-expanded database of Web of Science® (WoS, Thomson Reuters). The articles were analyzed by combining various bibliometric tools, such as science mapping and topic analysis, and a Technology Readiness Scale was adapted to assess the evolution of this emerging field. The number of analyzed publications was low (231), but the literature grew exceptionally fast. The "Engineering, Biomedical" was still the most represented WoS category. Some of the recent fronts were "hydrogels" and "stem cells", while "in vitro" remained one of the most used keywords. The number of countries and journals involved in bioprinting literature grew substantially in one decade, also supporting the idea of an increasing community. Neither the United States' leadership in bioprinting productivity nor the role of universities in publications were challenged. "Biofabrication" and "Biomaterials" journals were still the leaders of the bioprinting field. Bioprinting is a young but promising technology.
