Transfected BOECs detected in mouse marrow and spleen.
tBOECs are identified in murine tissues by peroxidase staining using an antibody to human β2-microglobulin. (A, C) Human tBOECs in murine marrow and spleen, respectively, at 156 days after administration. (B) Negative control—marrow from a NOD-SCID mouse that did not receive BOEC. (D) Positive control—monolayer culture of BOEC. Original magnification, × 600.
