Morphology of bone marrow cells in Tg mice.
Myeloid cells at various stages of differentiation were observed in bone marrow of wild-type (WT) G-CSFR Tg mice and littermates. In contrast, immature myeloid cells were prominent in truncation-mutant Tg mouse marrow. Original magnification × 1000; May-Grünwald-Giemsa stain.
