Abstract Background This study investigates the effect of autologous bone marrow transfusion (BMT) on the reconstruction of both bone marrow and the immune system in patients with AIDS-related lymphoma (ARL). Methods A total of 32 patients with ARL participated in this study. Among them, 16 participants were treated with conventional surgery and chemotherapy (control group) and the remaining 16 patients were treated with chemotherapy followed by autologous bone marrow transfusion via a mesenteric vein (8 patients, ABM-MVI group) or a peripheral vein (8 patients, ABM-PI group). Subsequently, peripheral blood and lymphocyte data subsets were detected and documented in all patients. Results Before chemotherapy, no significant difference in indicators was observed between three groups of ARL patients. Unexpectedly, 2 weeks after the end of 6 courses of chemotherapy, the ABM-MVI group, and the ABM-PI group yielded an increased level of CD8+T lymphocytes, white blood cells (WBC), and platelet (PLT) in peripheral blood in comparison to the control group. Notably, the number of CD4+T lymphocytes in the ABM-PI group was significantly higher than that in the other two groups. Additionally, no significant difference in haemoglobin levels was observed before and after chemotherapy in both the ABM-MVI and ABM-PI groups, while haemoglobin levels in the control group decreased significantly following chemotherapy. Conclusions Autologous bone marrow transfusion after chemotherapy can promote the reconstruction of both bone marrow and the immune system. There was no significant difference in bone marrow recovery and reconstruction between the mesenteric vein transfusion group and the peripheral vein transfusion group.

Background: Mesenchymal stem cells (MSCs) improve the cardiac function and remodeling in patients with ischemic heart disease. However, their presence in the circulating peripheral blood and post-transplantation has not been fully elucidated. We aimed to investigate the effects of intravenous transplantation of mobilized autologous peripheral blood on the number of MSCs in patients with ischemic heart disease. Methods: Granulocyte-colony stimulating factor (G-CSF, 5.0 μg/kg/day) was given subcutaneously once a day for five days to 7 patients (4 women and 3 men, aged 54-69 years) with ischemic heart disease. Leukapheresis procedure was started on the day 5 of G-CSF using the Spectra Optia cell separator. Circulating and intravenous transplantation of autologous MSCs after leukapheresis were analyzed by flow cytometry. MSCs were identified on the basis of dual positive cells (CD73 + /CD105 + or CD90 + /CD73 + or CD90 + /CD105 + ) and detected as MSCs if a cluster of at least 10 cells could be found. Results: MSCs in the circulating peripheral blood and after transplantation were detected in 2 (28%) and 6 (85%) patients, respectively. The frequency of intravenous peripheral blood MSCs increased significantly after transplantation (from 32.57 ± 22.76 x10 -4 % to 58.57 ± 28.49 x 10 -4 % , p<0.001). Moreover, there were significant rise in the total white blood cells count (from 10.25 ± 4.86 x 10 3 /μl to 35.81 ± 7.07 x 10 3 /μl, p<0.001) and the levels of CD34 + cells (from 1.17 ± 0.93 cells/μL to 138.30 ± 11.26 cells/μL, p<0.001) after the infusion. Conclusions: The results show that intravenous transplantation of mobilized autologous peripheral blood increases the number of MSCs in patients with ischemic heart disease. Leukapheresis product of peripheral blood MSCs could therefore be a potential source for autologous transplantation in ischemic heart disease.

Hereditary hemorrhagic telangiectasia (HHT) is a rare vascular disorder inherited in an autosomal dominant manner. Patients with HHT can develop vascular dysplasias called telangiectasias and arteriovenous malformations (AVMs). Our objective was to profile and characterize micro-RNAs (miRNAs), short noncoding RNAs that regulate gene expression posttranscriptionally, in HHT patient-derived peripheral blood mononuclear cells (PBMCs). PBMCs, comprised mostly of lymphocytes and monocytes, have been reported to be dysfunctional in HHT. A total of 40 clinically confirmed HHT patients and 22 controls were enrolled in this study. PBMCs were isolated from 16 mL of peripheral blood and purified for total RNA. MiRNA expression profiling was conducted with a human miRNA array analysis. Select dysregulated miRNAs and miRNA targets were validated with reverse transcription–quantitative polymerase chain reaction. Of the 377 miRNAs screened, 41 dysregulated miRNAs were identified. Both miR-28-5p and miR-361-3p, known to target insulin-like growth factor 1 (IGF1), a potent angiogenic growth factor, were found to be significantly downregulated in HHT patients. Consequently, IGF1 mRNA levels were found to be significantly elevated. Our research successfully identified miRNA dysregulation and elevated IGF1 mRNA levels in PBMCs from HHT patients. This novel discovery represents a potential pathogenic mechanism that could be targeted to alleviate clinical manifestations of HHT.
