The cell indicated by the arrow is an orthochromic normoblast. It is about 8 - 10 micrometers in diameter. It is the last stage of red cell maturation with a nucleus. The nucleus is small and dense. The cytoplasm is mostly pink due to its high hemoglobin content. The cell below the nucleated red blood cell is a lymphocyte. The lymphocte chromatin is smoother and the cytoplasm is bluer.
