HS II was weak in hematopoietic cell lines , absent in Hela , and greatly enhanced in Jurkat , suggesting that this region might be implicated in the cis-activation of tal-1 promoter 1b in this cell line.
 ( DNA: tal-1, None) , ( cell line: hematopoietic cell lines, None) , ( DNA: HS II, None) , ( cell line: Hela, None) , ( cell line: Jurkat, None) , ( DNA: tal-1 promoter 1b, None)
