Abstract

Bone marrow biopsy is useful for diagnosis of hematopoietic diseases. We have recently reported that bone marrow biopsy from the flipper might be useful for diagnosis of hematopoietic diseases in dolphins. In this study, to demonstrate whether biopsy from the flipper is useful for clinical diagnosis, we investigated the gene expression profiles and proliferation and differentiation of bone marrow mononuclear cell (BMMC) isolated from the humeral bone marrow of bottlenose dolphins. BMMC exhibited gene expression profiles considered to be characteristic of hematopoietic cells. Similarly, a colony forming unit assay showed that dolphin BMMC possessed vigorous colony forming ability. The proliferation of hematopoietic progenitor cells resulted in the formation of three types of colonies, containing neutrophils, monocytes/macrophages and eosinophils with or without megakaryocytes, all of which could be identified based on the morphological characteristics and gene expression profiles typically associated with hematopoietic markers. Thus, dolphin BMMCs from humeral bone marrow contain many hematopoietic progenitor cells, and bone marrow biopsy from the flipper is suggested useful for clinical diagnosis for the dolphins. © 2011 Elsevier B.V.
