Sino-Canadian collaborations in stem cell research: a scientometric analysis.

Ali-Khan SE, Ray M, McMahon DS, Thorsteinsdóttir H - PLoS ONE (2013)

Bottom Line: China-Canada collaboration enhances impact compared to papers authored solely by China-based researchers This difference remained significant even when comparing only papers published in English.Nevertheless, IC enhances the impact of stem cell research in China, and in the field in general.This study establishes an objective baseline for comparison with future studies, setting the stage for in-depth exploration of the dynamics and genesis of IC in stem cell research.

ABSTRACT

Background: International collaboration (IC) is essential for the advance of stem cell research, a field characterized by marked asymmetries in knowledge and capacity between nations. China is emerging as a global leader in the stem cell field. However, knowledge on the extent and characteristics of IC in stem cell science, particularly China's collaboration with developed economies, is lacking.

Methods and findings: We provide a scientometric analysis of the China-Canada collaboration in stem cell research, placing this in the context of other leading producers in the field. We analyze stem cell research published from 2006 to 2010 from the Scopus database, using co-authored papers as a proxy for collaboration. We examine IC levels, collaboration preferences, scientific impact, the collaborating institutions in China and Canada, areas of mutual interest, and funding sources. Our analysis shows rapid global expansion of the field with 48% increase in papers from 2006 to 2010. China now ranks second globally after the United States. China has the lowest IC rate of countries examined, while Canada has one of the highest. China-Canada collaboration is rising steadily, more than doubling during 2006-2010. China-Canada collaboration enhances impact compared to papers authored solely by China-based researchers This difference remained significant even when comparing only papers published in English.

Conclusions: While China is increasingly courted in IC by developed countries as a partner in stem cell research, it is clear that it has reached its status in the field largely through domestic publications. Nevertheless, IC enhances the impact of stem cell research in China, and in the field in general. This study establishes an objective baseline for comparison with future studies, setting the stage for in-depth exploration of the dynamics and genesis of IC in stem cell research.

pone-0057176-g001: Total worldwide stem cell papers by year.Shown is the total number of papers published worldwide in stem cell research by year, 2006–2010.

Mentions: In Figure 1 we present number of papers published worldwide in stem cell research between 2006–2010. Our search string generated 79,076 unique stem cell papers; 75% of these were articles, 21% were reviews and 4% were conference papers. The number of stem cell papers published globally increased from 12,700 in 2006, to 18,657 in 2010, an increase of almost 48%. Thus, our data indicate that the stem cell research field is growing rapidly. For comparison, a similar study showed a global doubling of stem cell publication numbers between 1991 and 2002 [22].
