Marrow biopsy. Fat cells are the clear ovoid or circular spaces and compose about three-quarters of the area of this section. Most of the remaining area is a clear pink matrix. No megakaryocytes are evident. Hematopoietic cells are profoundly decreased in number. In the aplastic marrow most of the cells are lymphocytes and occasional plasma cells.
