Morphology of Giant Nucleated Axolotl Erythrocytes
Morphology of axolotl (Ambystoma mexicanum) erythrocytes: giant nucleated cells with dense chromatin and an average MCV of 8000–12000 fL.
Articles
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.
