  1. @DHS: DNase Hypersensitive Site (from Figure 1; except for male hES (**) from UCSC).
  2. +P2 activity from RACE in Figure 2 or #[2]. *band observed with RACE, but not sequence-confirmed.
  3. ++YY1 binding from Figure 3, except ** from UCSC.
  4. +++DNA methylation is an average from 18 sites as shown in Figure 4.
