(English) Using flow cytometry we analyzed absolute and relative proportions of hematopoietic stem and progenitors cells (HSPC) populations including hematopoietic stem cells (HSC), multipotent progenitors (MPP), multilymphoid progenitors (MLP) and pro B cells from bone marrow of patients with mature B cell malignancies and in healthy controls. We found lower absolute and relative numbers of MLP and higher relative numbers of HSC were observed in patients when compared to age-matched controls irrespective of bone marrow (BM) involvement. On the other hand significantly decreased absolute numbers of MPP were observed only in patients who had their BM infiltrated by disease. We also confirmed published data showing increasing absolute and relative percentages of MLP with increasing age, decreasing relative percentages of HSC with increasing age, and decreasing absolute and relative pro B cell frequencies with increasing age in healthy subjects. While decreased absolute and relative pro B cell numbers were also found in patient samples as age increased, no significant correlations were detected in patients HSC, MPP or MLP populations. Age-related sub-analysis of PTs samples demonstrated that most of the disease associated changes in HSPC frequencies were observable more prominently in the elderly (>45...
