Objective: To investigate the apoptosis and its gene expression in bone marrow cells induced by Human parvovirus B19 (HPVB19).

Methods: In situ end-labeling (ISEL) was used to detect the apoptosis in bone marrow cells of 13 patients with aplastic anemia, and Immunohistochemical method was used to investigate the expression of the Bcl-2, Bax and Fas gene.

Results: The cell death by apoptosis is observed in 8 HPVB19-DNA positive patients, the expression of Bax and Fas are present in 3 patients (3/6). The apoptosis is not found in 5 HPVB19-DNA negative patients, the expression of Fas is present in only 1 patient (1/5). The expression of Bcl-2 is not found in 11 patients.

Conclusions: The HPVB19 may induce the overexpression of Bax and Fas, thus results in the apoptosis of bone marrow cells.
