Endothelial Cells in Bone Marrow Aspirate
How endothelial cells of blood vessels appear in bone marrow aspirate smears: morphological features and differential diagnosis.
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
