Metastasis of MM cells within SCID-hu mice. SCID-hu mice were treated with irradiation (400 cGy), injected directly into the marrow cavity of the left fetal human bone implant with 5 × 104 ARH-77 MM cells, and killed 12 weeks later. H&E (original magnification × 100 [A] and × 400 [B]) and immunoperoxidase staining with anti-κ Ig Ab (original magnification × 100 [C] and × 1,000 [D]) of the right-sided human fetal bone marrow implant is shown.
Mediastinum (original magnification × 40 [E]) and murine vertebral BM (original magnification × 400 [F ]) were also stained with H&E.
