From: HERV-H RNA is abundant in human embryonic stem cells and a precise marker for pluripotency
Cumulative expression of all HERV-H proviruses in human H1 ES cells (hESC), HeLa cells, or K562 cells, compared to expression of HERV-K and BRD2, a constitutive gene with the same expression level in all three cell types. In human ES cells, HERV-H is expressed 1000-fold higher than HERV-K and 25-fold higher than BRD2. HERV-H expression is barely detectable in HeLa, and no significant HERV-H expression was detected in K562 cells. RNASeq data for this analysis were from reference [33].
