Ancestry and relatedness

(A) Principal component analysis illustrates the genetic ancestry of hESC lines (red) relative to individuals from diverse populations (three-letter codes) from the 1000 Genomes project. hESCs with ad-mixed European or non-European ancestry are indicated by arrows. PC, principal component.

(B) Magnification of the hESC cluster from (A) showing hESC line clustering with different European ancestries.

(C) Sibship pedigree of hESC lines, where squares denote male, circles denote female, and the dashed line denotes a half-sibling relationship. See also Table S2 and Figure S1.
