Citation numbers were determined using the Web of Science database, and data were normalized as described in the Experimental Procedures section. In the case of hESC papers, work in which hESCs were only used as gold standard for hiPSC research was omitted. Only research from countries with at least 20 hESC and 15 hiPSC research papers, respectively, was included.
