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.

Introduction At Hiwa Cancer Hospital (Sulaymaniyah, Iraqi Kurdistan) after the center was started by a cooperative project in June 2016, autologous transplantation was developed. Patients and Methods To develop the project, the capacity-building approach was adopted, with on-site training and coaching of personnel, educational meetings, lectures, on-the-job training, and the implementation of quality management planning. Results Here, we report initial results of peripheral-blood stem-cell mobilization and collection of the first 27 patients (age 12 to 61 years; 19 males and 8 females; multiple myeloma, n = 10; plasma cell leukemia, n = 1; Hodgkin lymphoma, n = 12; non-Hodgkin lymphoma, n = 3; and acute myeloid leukemia, n = 1). Only three (11.5%) of 26 patients experienced a failure of mobilization. A median of 6.1 × 106/kg CD34-positive cells per patient were collected (range, 2.4 to 20.8), with two apheretic runs. Twenty-four patients underwent autologous transplantation. All but one transplantation engrafted fully and steadily, with 0.5 and 1.0 × 109/L polymorphonucleates on day 10.5 (range, 8 to 12) and day 11 (range, 9 to 15), respectively, and with 20 and 50 × 109/L platelets on day 13 (range, 10 to 17) and day 17 (range, 2 to 44), respectively. More than 95% of patients are projected to survive 1 year after autograft. Conclusion These data are the result of an Italian effort to establish in Iraqi Kurdistan a leading center for hemopoietic stem-cell transplantation. The capacity building approach was used, with on-site training and coaching as instruments for the development of provider ability and problem solving. With future limitations for immigration, this method will be helpful, especially in the field of high-technology medicine.

Abstract Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired hemolytic anemia resulting from a somatic mutation in a hemopoietic stem cell. In most cases of hemolytic PNH, the majority of the marrow cells are derived from the PNH clone. Recent evidence has indicated, however, that the majority of the most primitive peripheral blood stem cells (PBSCs) in PNH appear to be of normal phenotype. This has led to tentative suggestions that normal PBSCs could be collected and used for autologous transplantation. We have investigated this possibility in four PNH patients by treating them with granulocyte colony-stimulating factor (G-CSF) in an attempt to mobilize normal progenitors. The expression of glycosylphosphatidylinositol (GPI)-linked proteins was analyzed by flow cytometry on mature neutrophils, late stem cells (CD34+/CD38+), and primitive stem cells (CD34+/CD38−). The phenotyping and stem cell quantitation was performed in steady-state blood and post–G-CSF administration. The most primitive PBSCs (CD34+/CD38−) were almost all normal before G-CSF treatment, even when the patients' neutrophils were mainly PNH. However, after G-CSF, the cells that were mobilized into the peripheral blood were of a similar phenotype to the mature neutrophils, ie, mainly PNH. It is possible that PNH-stem cells are preferentially destroyed by complement in the peripheral blood leaving only normal cells in the circulation. After G-CSF, the PNH cells in the marrow are released into the blood. Our findings suggest that it would be difficult to collect sufficient numbers of normal stem cells for autologous transplantation.

Abstract Chemotherapy has been used clinically to mobilize hematopoietic progenitor cells into the peripheral blood so that they can be harvested for autologous transplantation. In humans, this is demonstrated by the presence of circulating granulocyte-macrophage colony-forming cells (CFU-GM) and CD34-positive cells, but it has not been possible to confirm the presence of marrow-repopulating stem cells. In this study, we treated mice with 200 mg/kg cyclophosphamide (CY) and measured the numbers of white blood cells, day 12 CFU-S (CFU- S12), and CFU-GM in the peripheral blood. There was a peak in the numbers of CFU-S12 and CFU-GM 8 days after treatment with cyclophosphamide. Peripheral blood cells taken at this time rescued lethally irradiated mice and engraftment of donor cells was confirmed after 140 days in sex mismatched recipients using a Y chromosome- specific probe. In vitro culture of the blood cells harvested after cyclophosphamide showed that they proliferated in suspension cultures for at least a year in the presence of interleukin-3. The cultured cells rapidly lost their abilities to rescue irradiated mice and to form colonies in vitro, but they did not become leukemic. Also, CY- treated mice were irradiated with a leukemogenic dose of x-rays to coincide with peak circulating cell numbers but these animals did not develop an excess of leukemias over mice given irradiation alone.

After myeloablative regimens, combined reinfusion of peripheral blood hematopoietic circulating progenitor cells (CPC) and bone marrow, yields a very rapid hematopoietic recovery. Therefore, based on the knowledge that CPC express the CD34 and CD33 differentiation antigen, we have developed a direct immunofluorescence flow cytometry assay to detect the peak of CPC in the peripheral blood of patients treated with high dose chemotherapy and growth factors. This assay, compared to CFU-GM assay, has the following advantages: 1) easy to do 2) standardized method 3) real time information on CPC number. This work illustrates the practical aspects of this assay and substantiate the widespread use of the CD34/33 flow cytometry assay to guide harvesting of circulating hematopoietic progenitors for autologous transplantation.
