Low Power View of Biopsy

This low power view of a hematoxyln and eosin stained bone marrow biopsy shows fat cells as clear circles, and the darker intervening areas as blood cell precursors. This biopsy is about 25% cellular, or mildly hypocellular. A normal marrow in a middle aged adult is about 50% cellular.
