  • Title: [Study on the stroma of patients with paroxysmal nocturnal hematoglobinuria].
    Author: Han B, Wu Y, Zhang Z.
    Journal: Zhonghua Yi Xue Za Zhi; 2001 Dec 10; 81(23):1430-3. PubMed ID: 11930614.
    Abstract:
    OBJECTIVE: To investigate the relationship between the stroma of bome marrow and the abnormality of hematopoiesis in patients with paroxysmal nocturnal hematoglobinuria (PNH). METHODS: The bone marrow stromata from PNH patients was compared with those from normal volunteers in aspects of their CFU-F formation and hematopoietic sustentation for normal CD34+ cells. The stromal IL-6 and TNF-alpha mRNA expression in patients and normal volunteers was also measured by RT-PCR(self beta-actin as contrast). RESULTS: (1) The CFU-F formation ability in PNH patients was very similar to that in normal volunteers (P > 0.05). (2) The bone marrow stromata from patients with PNH had the same hematopoietic maintenance compared to those from normal controls (P > 0.05). (3) The stomal IL-6 and TNF-alpha mRNA expression was similar in PNH patients and in normal volunteers (P > 0.05). CONCLUSION: The CFU-F formation capacity of bone marrow fibroblast was normal in PNH patients. The stromata in patients with PNH had normal hematopoietic maintainence to the normal CD34+ cells. The mRNA expression of IL-6 and TNF-alpha in PNH stromata was almost normal.
