Morphology of peripheral CD11b⁺ cells.

Microscopic appearance of representative cytospins revealed by May-Grünwald-Giemsa (original magnification, × 600) showing transgenic (Tg) and wild-type (Wt) peripheral CD11b⁺myeloid cells (monocyte, mature granulocyte, Ring form granulocyte). Transgenic myeloid cells expressed the Sca-1 antigen. No difference in the morphology between wild-type and transgenic mature myeloid cells could be seen. Straight arrow indicates a monocyte; marked arrow, mature granulocyte; herringbone arrow, ring-form granulocyte.
