Osteoblasts in Bone Marrow Aspirate: Morphology

Morphological features of osteoblasts in bone marrow aspirate: eccentric nucleus, perinuclear zone, and differential diagnosis with carcinoma cells.

Bone marrow smear: cluster of normal osteoblasts
Bone marrow smear: cluster of normal osteoblasts

The correct answer to the closed club of laboratory hematologists challenge. B. Cluster of normal osteoblasts. Osteoblasts are cells with an eccentrically located nucleus, abundant basophilic cytoplasm, and a clear zone (Golgi apparatus), which in clusters can mimic carcinoma cells. The clear zone is located behind a “layer” of basophilic cytoplasm. 🏆 Congratulations to the winners!

👉To join the closed group of laboratory hematologists, winners simply need to write to the instructor: “I want to join the elite club of specialists.” Then Evgeny Gennadievich will send a private invitation in response. WRITE TO THE INSTRUCTOR→ The winners of this week’s challenge are:
