Shown is the strength of China’s collaboration (indicated by Salton’s measure – the larger the number, the stronger the mutual strength of the collaboration between the two countries) with the other top 10 global producers of stem cell research, as well as for comparison – the Stem Cell Network Asia Pacific (SNAP) members, Hong Kong, and emerging economies India and Brazil.
