Overview of the human cell line data used in this paper.

Cell line	Tissue	Description	# ChIP-seq TFs	# DNase peaks
A549	Lung	Alveolar carcinoma	19	176,870
H1HESC	Stem cell	Male embryo stem cell	35	258,188
HELAS3	Cervix	Cervical adenocarcinoma	38	199,188
HEPG2	Liver	Hepatocellular carcinoma	45	192,959
GM12878	Blood	B-lymphoblastoid cells	58	183,953
K562	Blood	Erythrocytic leukemia	59	202,266

For each cell line we show the number of transcription factors (TFs) with ChIP-seq data and the number of DNase-seq peaks (open chromatin regions).
