  • Title: Splenic haematopoiesis in patients with cirrhosis of the liver.
    Author: Palitzsch KD, Falk S, Müller H, Stutte HJ.
    Journal: Virchows Arch A Pathol Anat Histopathol; 1987; 411(2):179-83. PubMed ID: 3111081.
    Abstract:
    Hitherto it has generally been assumed that splenic haematopoiesis in adult humans occurs very infrequently and is predominantly associated with haematological disorders. In the present study of patients with cirrhosis of the liver, a marked splenic haematopoiesis was a constant finding. Moreover, low-level splenic erythro- and granulopoiesis was highly prevalent even in haematologically normal controls, while splenic thrombopoiesis was conspicuously absent in both groups. We suggest that splenic haematopoiesis results from entrapment and proliferation of circulating haematopoietic precursor cells in the splenic red pulp. This would account for the presence of splenic haematopoiesis in normal controls as well as in patients with cirrhosis of the liver. In the latter, stimulation of bone marrow haematopoiesis and increased splenic pooling of haematopoietic precursor cells may contribute to the marked increase of splenic haematopoiesis observed.
