Figure 1. The potential latency phenotypes in CD34⁺ hematopoietic progenitor cell model.

Pre-reactivation is the virus produced prior to the reactivation as determined by measuring infectious centers in the lysate controls (light grey bars). The frequency of reactivation (dark grey bars) is determined by infectious centers obtained by the co-culture of viable, latently infected CD34⁺ cells with fibroblast monolayers.
