In monopoiesis, which stage shows a kidney bean nucleus with lacy chromatin and vacuoles in the cytoplasm?

The stage described is the monocyte. During monopoiesis, the nucleus evolves from round in earlier precursors to a kidney-shaped (reniform) form in circulating monocytes. The chromatin becomes fine and lace-like, and the cytoplasm shows vacuoles as the cell becomes phagocytic. Macrophages in tissues derive from these monocytes and can have more cytoplasm and different nuclear contours, but the distinctive kidney-shaped nucleus with lacy chromatin and cytoplasmic vacuoles points to the monocyte stage.
