A 5' control region of the human epsilon-globin gene is sufficient for embryonic specificity in transgenic mice.


When introduced as part of DNA constructions containing the human beta-globin locus control region (LCR), the human embryonic beta-globin gene, epsilon, is expressed in primitive but not definitive erythroid cells of recipient transgenic mice. In contrast to this pattern, the human fetal beta-globin gene, gamma, has been shown to be expressed in both… (More)
