Virus titer was determined using routine plaque assay with HEL cells. Supernatants from HCMV-infected and mock-infected CD34+-derived macrophages were cocultured with HEL cells for 14 days. Virus titer recovered from the supernatants of the macrophages derived from CD34+ cells infected with clinical isolate was 3 × 10 PFU/mL. No virus was recovered from the supernatants of the macrophages derived from CD34+ cells infected with recombinant laboratory strain.
