2.Progress of research and application on hematopoietic stem cell transplantation by intra-bone marrow injection--review.
Journal of Experimental Hematology 2006;14(1):179-182
The purpose of hematopoietic stem cell transplantation by intra-bone marrow injection (IBM-HSCT) is to facilitate the homing of HSC. It has been recently proven in many animal experiments that different kinds of donor cells could efficiently home and engraft into the bone marrow by IBM-HSCT, which led to the rapid hemopoietic and immune recovery of recipients, preventing the development of GVHD, inducing the donor-specific tolerance in allogeneic organ transplantation, and promoting the survival rate of recipients. In this review, the effect of IBM-BMT and IBM-UCBT, the application of IBM injection technique in the study on HSC's biological characteristics, and its prospect for clinical HSCT were summarized.

In order to explore the security and feasibility of double autologous peripheral blood stem cell transplantation (APBSCT) for treatment of multiple myeloma, a 49 years old female patient with multiple myeloma was therapied with double APBSCT. The first peripheral blood stem cell (PBSC) mobilization regimen included CTX 2 g/m(2) x 1d and G-CSF [10 microg/(kgxd)] x 5 d. The conditioning regimen was given melphalan 200 mg/m(2). The transplanted number of mononuclear cells was 6.1 x 10(8)/kg and that of CD34(+) cells was 4.7 x 10(6)/kg. The second APBSCT was performed six months later. PBSC mobilization regimen was G-CSF [10 microg/(kgxd)] x 5 d. The conditioning regimen was melphalan 200 mg/m(2). The transplanted number of mononuclear cells was 10.2 x 10(8)/kg and that of CD34(+) cells was 5.9 x 10(6)/kg. The results showed that the absolute neutrophil count (ANC) rose to above 0.5 x 10(9)/L on day 17 and platelet count exceeded 20 x 10(9)/L on day 15 after first transplantation. After second transplantation ANC rose to above 0.5 x 10(9)/L on day 22 and platelet count exceeded 20 x 10(9)/L on day 13. There were neither obvious adverse reaction nor severe complication during the double transplantations. The patient's ostealgia and anemia were healed through above therapy. In the follow-up of 7 months, the patient's general status was good and she remained in complete remission phase. It is concluded that double APBSCT is safe, effective and feasible for the treatment of multiple myeloma.

This study was purposed to explore the effectiveness of mixed transplantation of HLA mismatched bone marrow hematopoietic stem cells(HSC), peripheral blood HSC and umbilical cord blood HSC for treatment of pediatric blood diseases. From August 2012 to December 2012, five children with refractory hematological diseases in our hospital received allogeneic hematopoietic stem cell transplantation. The mixed grafts consisting of HLA-mismatched bone marrow HSC, peripheral blood HSC and umbilical cord blood HSC were used to observe the effects of umbilical cord blood HSC on the time of hematopoietic reconstruction of bone marrow, STR chimeric degrees, incidence of GVHD. and early transplant-associated complications. The results showed that all 5 children patients were grafted successfully with the median grafted time of 11 d for ANC>0.5×10(9)/L and 10 d for Plt>20×10(9)/L, respectively. On day 30, the STR-PCR test of peripheral blood showed a stable complete chimera. Five cases suffered from mild to moderate symptoms of GVHD, showing with I-II grade of skin GVHD and in which two cases suffered from diarrhea, showing I-II grade of intestinal GVHD. All the 5 patients had no liver function damage. One patient died of severe hemorrhagic cystitis and multi-site infection, and the remaining four cases survived so far on the current median follow-up time of 137 d (130 d-250 d). It is concluded that transplantation of the mixed HLA mismatched bone marrow HSC, peripheral blood HSC, with third-party cord blood HSC can increase the survival rate for pediatric patients with blood disease.

To evaluate the yield of the blood cell separator for collection of peripheral blood stem cells (PBSC) from ABO major and (or) minor incompatible allogeneic donors and the feasibility of PBSC component infusion to the recipients without removal of erythrocytes or plasma, the Cobe Spectra (Version 6.1) blood cell separator was utilized to collect PBSC component from 9 allogeneic donors. Of all the donors, 4 were ABO major incompatible, 2 were minor incompatible and the other 3 were both major and minor incompatible to corresponding recipients. In each cycle, different amount of PBSC component was harvested, and the variable volume plasma chased the cells into the bag was adjusted according to the ABO incompatibility. The nucleated cell count, percentage of mononuclear cell, number of CD34(+) cell and percentage of viable cell (trypan blue excluding rate) in the component were detected. At the time of infusion, a series of protective measures to the renal function of recipients were taken. The results showed that apheresis was twice performed on these eight donors to collected enough PBSC for transplantation or cryopreservation, except one apheresis was enough for cell amount needed by transplantation, as the donor's body weight was much heavier than that of the recipient. Altogether 17 apheresises were performed, the mean yield of nucleated cells was 3.77 x 10(10), in which 97% to 99% were mononuclear cells (MNC). The harvested number of CD34(+) cell was 8.62 x 10(6)/kg. All the trypan blue exclusion rate was 100%. In ABO major incompatible or both major and minor incompatible component, there were 8 - 10 ml packed erythrocytes; in ABO minor incompatible component, there were 80 - 120 ml of plasma. These components were infused into the recipients without removal of erythrocytes or plasma and no haemolytic reaction was observed in any recipient, and their hematopoietic functions soon recovered. Results suggest that enough PBSC can be acquired by using blood cell separator Cobe Spectra (Version 6.1), with the modified separation factors, and the collected PBSC component can be safely infused into the ABO incompatible recipients without removal of erythrocytes or plasma.

OBJECTIVETo analyze the efficacy and its correlation with species of transplant cells of autologous mobilized peripheral blood (PB) mononucleated cells (MNCs) transplantation on 59 patients with lower limbs ischemia.
METHODSFifty-nine patients were evaluated with symptoms scores and after that their PBMNCs were mobilized and collected and then injected into the ischemic area at equal distance. They effectiveness and scores were evaluated at 7th day and 4th month after therapy. The correlation of CD34(+) cells and of MNCs with effectiveness was analysed respectively, and formula for correlations between them and effectiveness was calculated.
RESULTSAfter MNCs injection, the effectiveness was observed both at 7th day and 4th month. The correlation of MNCs with effectiveness was stronger than that of CD34(+) cells (the effectiveness was represented by nimodipine value), According to the formula of nimodipine value, the value of the latter = 0.484 + 1.055 × CD34(+) cells number and the former = 0.288 + 0.401 × MNCs number with a correlation coefficient of R = 0.461 (P = 0.047) and R = 0.473 (P = 0.000) respectively.
CONCLUSIONAutologous mobilized PBMNCs number is a better indicator for effectiveness than CD34(+) cells number.

Depletion of T and B cells from the graft is prerequisite for haploidentical transplantation to decrease the risk of GVHD and EBV-associated lymphoproliferative disease. This study was aimed to investigate the performance of T-cell and B-cell simultaneous depletion from mobilized peripheral blood stem cells (PBSCs) for the first time in China, using anti-CD3 and anti-CD19 antibodies conjugated to magnetic microbeads by the CliniMACS device. The depletion efficiency of T-cell and B-cells was analyzed by flow cytometry; the function of the stem cells after depletion was evaluated using colony assays. The results indicated that the mononuclear cell count prior to T- and B-cell depletion was 4.88 x 10(10). After depletion, the percentage of T cells was 0.02% with a log (10) depletion of 4.4. The percentage of B cells was less than 0.01% with a log (10) depletion of at least 3.3. The product contained not only CD34(+) stem cells, but also NK cells, monocytes and granulocytes. After T- and B-cell depletion the purity of CD34(+) cells was 0.98%, the number of CD34 cells was 1.84 x 10(8) and their recovery rate was 69.7%. The number of NK cells was 2.54 x 10(9) and the recovery rate of NK cells was 71.7%. In vitro colony assays showed no negative impact on function of the hematopoietic stem cells. In conclusion, the CliniMACS system can be used to efficiently deplete T and B cells from PBSCs simultaneously, without adverse effect on biological function of hematopoietic stem cells. This study provides technical platform for haploidentical hematopoietic stem cell transplantation.

OBJECTIVETo compare the hemopoietic reconstitution, immune reconstitution, infection, incidence of graft-versus-host disease (GVHD) and clinical outcome between unrelated donor peripheral blood stem cell (PBSC) transplantation and bone marrow (BM) transplantation for leukemias.
METHODSThe clinical results of 21 leukemia patients receiving G-CSF mobilized PBSC graft from unrelated donors were compared with that of 32 patients receiving unrelated BM transplants.
RESULTSCompared with BM grafts, the PBSC graft contained significantly more nucleated cells (P = 0.000), and resulted in a significantly shorter time-to-neutrophil (12.43 +/- 3.67 vs 16.16 + 2.99 days) and platelet engraftment (14.67 +/- 6.19 vs 21.23 +/- 8.25 days), (P = 0.000 and 0.003, respectively). T cell reconstitution between the two groups differed little after transplantation. The incidences of early-stage infection (42.86% vs 53.13%), the probabilities of acute graft-versus-host disease (aGVHD) (61.90% vs 71.88%), the grades III to IV aGVHD (23.81% vs 15.63%), the chronic GVHD (47.06% vs 43.48%) and the probabilities of relapse (6.90% vs 12.50%) between PBSC and BM groups all has no statistical significance (NS). The 2-year disease free survival (DFS) rates of the two groups were (50.14 +/- 12.00) % and (59.81 +/- 8.99)%, respectively also have no NS.
CONCLUSIONG-CSF-mobilized unrelated donor PBSCs engraft more rapidly in the recipients as compared with conventional BM grafts. The T cell reconstitution, the incidence of infection, the incidence and severity of aGVHD and cGVHD, and the 2-year DFS rates between the two groups all have no significant differences.

The purpose of this study was to compare the efficacy of CEP plus G-CSF and CVP plus G-CSF regimens in the mobilization and collection of peripheral blood hematopoietic stem cells (PBHSC), and in the hematopoietic recovery. 57 patients with non-Hodgkin's lymphoma (NHL) underwent autologous PBHSC transplantation were analyzed retrospectively. The PBHSC were mobilized and collected by using CEP plus G-CSF and CVP plus G-CSF respectively, and were retransfused into these NHL patients after preconditioning, then the mobilization efficacy, adverse reactions and hematopoietic recovery were analyzed. The results showed that the WBC count decreased to ≤ 1.0 × 10(9)/L, platelet amount dropped to ≤ 40 × 10(9)/L during peripheral blood stem cell mobilization of all patients, which indicated successful collection of PBHSC. The mean value of (4.38 ± 3.40) × 10(8)/kg mononuclear cells (MNC) containing (2.79 ± 2.53) × 10(6)/kg CD34(+) cells were collected in CEP plus G-CSF group, while the mean value of (3.31 ± 1.23) × 10(8)/kg MNC containing (2.02 ± 0.87) × 10(6)/kg CD34(+) cells were collected in CVP plus G-CSF group. The efficacy of mobilization in CEP plus G-CSF group was significantly higher than that in CVP plus G-CSF group (p < 0.05). After preconditioning, bone marrow was suppressed in all patients. The average time of WBC count recovery to ≥ 1.0 × 10(9)/L was 11.4 days in CEP plus G-CSF group and 12.3 days in CVP plus G-CSF group; the average time of platelet amount recovery to ≥ 50 × 10(9)/L was 18.6 days in CEP plus G-CSF group and 19.3 days in CVP plus G-CSF group. The statistical analysis showed no significant difference in the average time of hematopoietic recovery between 2 groups. It is concluded that autologous PBHSC transplantation shows significant effect for treatment of patients with NHL. Either modified CEP or CVP plus G-CSF regimen is safe and effective in PBHSC mobilization. The CEP plus G-CSF regimen is better than CVP plus G-CSF regimen.
