Abstract Primary graft failure is usually associated with a high mortality rate despite infusion of back up graft and haematopoietic growth factors. In animal models mesenchymal stem cells (MSC) stimulate haematopoiesis recovery after TBI and enhance engraftment of haematopoietic stem cells (Almeida-Porada et al, Exp hematol 1999). Co-infusion of autologous blood stem cells and MSC in cancer patients receiving high dose chemotherapy speed up haematopoietic recovery (Koç et al, JCO 2000). We have previously shown that MSC can engraft and improve the bone marrow microenvironment in a patient with end stage severe aplastic anaemia (Fouillard et al, Leukemia 2003). We report a patient treated with MSC for aplastic anemia secondary to engraftment failure. A 40 year old nulliparous woman with acute myeloid leukaemia received an autologous bone marrow transplantation; conditioning regimen combined a 12 Gray TBI and cyclophosphamide (120 mg/kg). Primary graft failure occurred and persited despite back up marrow infusion. Partial recovery on polymorphonuclear (PMN) and haemoglobin (Hb) was obtained with granulocyte colony stimulating factor (G-CSF) and EPO. Thrombocytopenia remained below 50x109/l. No residual leukaemic cells were detected Three years after ABMT, allogeneic MSC were infused at a dose of 2,78x106/kg. MSC were isolated from a HLA mismatched brother bone marrow (Osiris Therapeutics Inc Baltimore, MD). At time of MSC infusion, the marrow aspirate was hypocellular with no leukaemic blast cells. Blood cell counts were: PMN: 0.8x109/l, platelets: 45x109/l and Hb: 10.5 g/dl. No conditioning regimen and no prophylaxis of GVHD was given. Growth factors were discontinued. After MSC infusion, a rapid haematopoietic recovery was observed on both PMN and platelet which reached a normal level. With a follow up of 18 months, the patient is alive and well. Recovery of haematopoiesis was corroborated by an improvement of in vitro haematopoietic and stromal clonogenic assays. CFU-GM and CFU-F studied the day before MSC infusion, one month and one year after MSC infusion, increased strikingly (p<0.05). LTC-IC increased significantly one year after MSC infusion (p<0.05). There was no change in BFUE. To further characterize the effects seen on haematopoiesis, we utilized a custom RayBiotech antibody array and compared proteins secreted by MSC of recipient before and one year after infusion. This array evidenced an increased secretion of proteins implied in haematopoiesis (Flt3l, GM-CSF, G-CSF, IL1, IL6, TPO, SDF1) one year after MSC infusion. Real time PCR confirmed an up-regulation of gene expression for GCSF, GM-CSF, IL1, IL6. We studied MSC engraftment. We analysed the bone marrow biopsy extracted DNA for mesenchymal chimerism before MSC infusion, one month and one year post MSC infusion by real time quantitative PCR of the Y specific SRY gene: male DNA was not detected before infusion; a level of male DNA of 1/105 was detected one month after MSC infusion. This observation shows that MSC can induce haematopoietic tissue repair. MSC should be considered in the treatment of engraftment failure and other bone marrow failure states including severe idiopathic aplastic anaemia and accidental irradiation.

Abstract Mesenchymal stem cells (MSC) are multipotent cells that are considered one of the most promising product for cellular therapy in regenerative medicine. MSC have been obtained and expanded from bone marrow and umbilical cord blood in adequate amounts for clinical applications. Under the right conditions, MSC could migrate from bone marrow into the peripheral circulation; however MSC have not been routinely isolated from peripheral blood, and studies are rare and not conclusive. The aim of the present study was to evaluate mobilised peripheral blood (MPB), obtained from patients undergoing apheresis collection of circulating hematopoietic progenitor cells, as a potential source of MSC for clinical applications. MPB samples (500–900 × 106 cells, N = 17) were separated by negative lineage-depletion immunoselection (RosetteSep). Selected cells were seeded in multi-well plates at low density in MesenCult Basal Medium without and with different combinations of growth factors (EGF, PDGF-BB, b-FGF). On reaching confluence, adherent cells were detached by 0.25% trypsin-EDTA treatment and replated for at least two passages. At each passage, surface antigen expression was analyzed by flowcytometry (CD45, CD34, CD105, CD44, CD73, CD166, CD31, HLA-DR and VE-caderine). Following immunoselection 9.5–17.1 × 106 cells were recovered from MPB samples. Cultured cells reached confluency in 3–4 weeks on first passage and in two weeks thereafter. Immunophenotyping showed negativity for CD45 antigen. The absence of growth factors in culture medium conditioned MSC growth capability, while the addition of PDGF-BB+EGF or b-FGF was able to boost the number of CD45−/CD73+/CD90+ cells in culture (see figure). However expansion remains still sub-optimal, having been reached in 8/17 samples. In conclusion, we demonstrate that MSC can be obtained from MPB, but expansion requires longer time period and appears more difficult compared to bone marrow. Therefore, further studies need to be conducted to find better culture conditions and optimal growth factor combinations to support MPB-derived MSC expansion. Figure Figure

Background: Bone marrow mononuclear cells (BM-MNCs), as a collection of hematopoietic and mesenchymal stem cells (MSCs), are capable of producing all blood cell lineages. The use of cytokines, growth factors, or cells capable of secreting these factors will help in stimulating the proliferation and differentiation of these cells into mature cell lines. On the other hand, MSCs are multipotent stromal cells that can be differentiated into various cell lineages. Moreover, these cells can control the process of hematopoiesis by secreting cytokines and growth factors. The present study aimed to investigate the effect of BM-derived MSCs on the differentiation of MNCs based on the assessment of cell surface markers by flow cytometry analysis. Methods: For this purpose, the MNCs were purified from rat BM using density gradient centrifugation. After that, they were cultured, expanded, and characterized. Next, BM-derivedMSCs were co-cultured with MNCs and then were either cultured with MNCs alone (control group) or co-cultured MNCs with BM derived-MSCs (experimental group). Finally, they were collected on day 7 and subjected to flow cytometry analysis for granulocyte markers and ERK protein’s investigation. Results: It was found that the expression levels of CD34, CD16, CD11b, and CD18 granulocyte markers, as well as protein expression of ERK, have significantly increased in the experimental group compared to the control group. Conclusion: Therefore, it can be concluded that MSCs could affect the granulocyte differentiation of MNCs via ERK protein expression, which is a key component of the ERK signaling pathway.
