Almost all cells underwent gene recombination within the first 10 h and as endoglin is a relatively stable protein with a half-life estimated as around 17 h [50], homogeneous endothelial cell cultures were obtained within the first 60 h after infection with endoglin levels ranging from normal and half reduced to complete loss as shown by staining and Western blot analyses (Figure 5C–E). The gene discussed is ENG; the disease is infection.
