Abstract
Pyruvate kinase deficiency (PKD) is a rare erythroid metabolic disease caused by mutations in the PKLR gene. Erythrocytes from PKD patients show an energetic imbalance causing chronic non-spherocytic hemolytic anemia, as pyruvate kinase defects impair ATP production in erythrocytes. We generated PKD induced pluripotent stem cells (PKDiPSCs) from peripheral blood mononuclear cells (PB-MNCs) of PKD patients by non-integrative Sendai viral vectors. PKDiPSCs were gene edited to integrate a partial codon-optimized R-type pyruvate kinase cDNA in the second intron of the PKLR gene by TALEN-mediated homologous recombination (HR). Notably, we found allele specificity of HR led by the presence of a single-nucleotide polymorphism. High numbers of erythroid cells derived from gene-edited PKDiPSCs showed correction of the energetic imbalance, providing an approach to correct metabolic erythroid diseases and demonstrating the practicality of this approach to generate the large cell numbers required for comprehensive biochemical and metabolic erythroid analyses. Patient-specific PKDiPSCs are generated from PB-MNCs by a non-integrative system PKDiPSCs are gene edited to insert a partial co-RPK in the PKLR locus mediated by TALEN An SNP in the homology arm leads to allele-specific homologous recombination Gene-edited PKDiPSCs generate a high number of metabolically corrected erythroid cells

Abstract
BACKGROUND The introduction of molecular methods into routine blood typing is prompting the identification of new blood group alleles. Discrepancies between the results of genotyping and serology or chance events uncovered during genotyping prompted additional investigations, which revealed six new RHCE variant alleles. STUDY DESIGN AND METHODS Samples from eight blood donors, two patients (one prenatal), and a patient's relative, all of diverse racial origin, were analyzed by standard serology methods, targeted genotyping arrays, DNA sequencing, and allele-specific polymerase chain reaction. RESULTS Six new RHCE alleles were identified, namely, RHCE*cE84A, RHCE*ce202G, RHCE*ce307T, RHCE*Ce377G, RHCE*ce697G,712G,733G,744C, and RHCE*Ce733G. CONCLUSION While implementation of new assays in commercial genotyping platforms to detect the polymorphisms reported here may not be justified given their apparent rarity, software interpretative algorithms may benefit from the identification of new alleles for a more accurate determination of genotypes and prediction of phenotypes.

Abstract
We analyze the origin of the electrical resistance arising in domain walls of perpendicularly magnetized materials by considering a superposition of anisotropic magnetoresistance and the resistance implied by the magnetization chirality. The domain wall profiles of L1(0)-FePd and L1(0)-FePt are determined by micromagnetic simulations based on which we perform first-principles calculations to quantify electron transport through the core and closure region of the walls. The wall resistance, being twice as high in L1(0)-FePd than in L1(0)-FePt, is found to be clearly dominated in both cases by a high gradient of magnetization rotation, which agrees well with experimental observations.

Abstract
Autologous bone marrow transplantation is an alternative therapeutic option for acute myeloid leukemia patients lacking a compatible donor. However, bone marrow from these patients may contain residual leukemic cells that should be ideally eliminated prior to the infusion of the graft. With the aim of developing more efficient protocols of graft purging, adenoviral-mediated gene transfer protocols have been conducted. We studied whether suicide adenoviral vectors expressing the cytosine deaminase gene (AdCD) could be used for selectively killing leukemic WEHI-3B cells. The AdCD transduction followed by the 5-fluorocytosine exposure abrogated the growth of WEHI-3B cells in vitro, with a minimal effect on normal hematopietic progenitors. To test the efficacy of the purging protocol in vivo, bone marrow cells were mixed with syngenic WEHI-3B cells and this chimeric cell population was transduced with AdCD vectors. Infected cells were injected into myeloablated Balb-c mice, which then received a 5-fluorocytosine treatment for 4 days. All mice transplanted with unpurged bone marrow developed leukemia and died. However, 90% of recipients receiving the purging treatment were healthy up to 9 months post-transplantation and had a perfectly re-established hematopoietic system, without any signal of leukemic cell presence. In conclusion, suicide adenoviral vectors are proposed as a tool for the purging of Adenoviral-susceptible myeloid leukemia cells contaminating autologous bone marrow grafts.

Abstract
HLA-C has been described as a transplantation locus in the unrelated bone marrow transplantation setting, and noticeably the number of mismatches between HLA-A,-B,-DRB1 compatible pairs is considerably high. Sequencing based typing (SBT) is an accurate and efficient methodology utilised in the HLA class I and II allele level of resolution. SBT for HLA-C locus was applied on a sample of 40 HLA-A,B,DRB1,DRB3/4/5,DQB1-compatible bone marrow recipient-donor pairs, and 3 new HLA-C alleles have been found. Cw*0307, well defined by serology as Cw3, showed two amino acid changes at the NK motif 77-80 regarding all described Cw*03 alleles, N77K80 instead of S77N80. Two new Cw*05 alleles were described, Cw*0502 properly typed by serology, and Cw*0504 that behaves as a short antigen. Cw*0502 differed from Cw*0501 by only one nucleotide at exon 3, that generated an amino acid replacement at codon 177, K to E. Cw*0504 differs from Cw*0501 by two clustered amino acid positions (114 and 116) placed at the peptide binding site. The rate of new HLA-C alleles found in this small series evidences a high grade of hidden HLA-C diversity in the Spanish population, particularly in the well-defined serologic specificities.

Abstract
BACKGROUND AND OBJECTIVES We analyzed the relationship between long-term hematopoietic recovery and the number of CD34+ cells infused in order to determine the optimal dose of CD34+ cells for rapid and stable engraftment. PATIENTS AND METHODS Between November 1993 and December 1998, 96 consecutive autologous transplantations were performed in 92 pediatric patients with different malignancies. Peripheral blood progenitor cells (PBPC) were mobilized by G-CSF alone (12 microg/kg/day s.c., Neupogen((R)); Amgen, Thousand Oaks, Calif., USA) and collected using a Cobe Spectra blood cell separator (Cobe, Denver, Colo., USA) through a central venous catheter with double lumen. The CD34+ cell contents of apheresis products were assessed by means of flow-cytometric analysis using an Epics Elite flow cytometer (Coulter, USA). RESULTS The median number of CD34+ cells infused was 3.2 x 10(6)/kg (range 0.17-44.4). The median times for short-term engraftment (neutrophil count >0.5 x 10(9)/l and platelet count >20 x 10(9)/l) was 9 (range: 7-16) and 13 days (range: 7-91), respectively. The median times for long-term engraftment (platelet count >50 x 10(9)/l and >100 x 10(9)/l) was 21 (range: 10-249) and 45 days (range: 12-288). When the infused CD34+ cell dose was >/=5 x 10(6)/kg (median 7.99, range 5.01-44.4), there was a statistically significant increase in the rate of short- and long-term hematopoietic recovery compared to patients transplanted with a lower number of CD34+ cells (p < 0.0001). The earlier recovery in the high CD34+ cell group resulted in less transfusional support, fewer days on intravenous antibiotics and shorter hospitalization. CONCLUSIONS This study confirms that G-CSF-mobilized PBPC provide rapid short- and long-term hematopoietic engraftment in pediatric patients undergoing autologous transplantation if a CD34+ cell dose >/=5.0 x 10(6)/kg is infused. As this PBPC dose seems to have clinical and potentially economic implications, it should be considered the optimal dose for apheresis.

Abstract
The study of HLA class II polymorphism by direct exon 2 DNA sequencing analysis has been established to be a reliable and accurate high-resolution typing procedure. This approach shows some advantages in relation to previous methods, polymerase chain reaction using sequence-specific oligonucleotides (PCR-SSO) and sequence-specific primers (PCR-SSP), basically due to the capability of analysis for the complete sequenced genomic region, including non-polymorphic motifs. DRB3 and DQB1 sequencing based typing (SBT) in unrelated bone marrow donor searching allowed us to detect three new alleles. The complete coding region sequences were characterised from cDNA. Two new DRB3 alleles, DRB3*0210 and DRB3*0211, were described in two Caucasian bone marrow donors. Both sequences showed single point mutations regarding DRB3*0202, producing amino acid replacements at positions 51 (Asp to Thr) and 67 (Leu to Ile), respectively. These two point mutations can be found in other DRB alleles, and suggest that gene conversion would be involved in the origin of both alleles. A new DQB1 sequence was found in a Spanish patient that showed two nucleotide differences, positions 134 and 141, with regard to its close similar DQB1*03011 allele. Only substitution at position 134 provoked amino acid replacement at residue 45, Glu to Gly. This single amino acid change would be involved in the lack of serologic recognition of this new molecule by DQ7-specific reagents.

METHODS Tissue culture, integrin expression vectors, gene transfer, polymerase chain reaction (PCR), apoptosis analyses and cytometic analysis were made on hematopoietic cells. RESULTS The beta 5 integrin cDNA was not expressed in hematopoietic cells following exposure to the beta 5 integrin retrovirus vector pG beta 5CHT. Unbalanced expression of the alpha v beta 3 and alpha v beta 5 integrins occurred during apoptosis induced by serum depletion and upon differentiation. The treatment of hematopoietic cells with anti-alpha v beta 5 monoclonal antibody inhibited apoptosis induced by serum depletion. Inducible expression of the beta 5 integrin cDNA in the hematopoietic cell line K562 caused cellular proliferation inhibition. CONCLUSION The alpha v beta 5 integrin cDNA in hematopoietic cells can inhibit the proliferation of the hematopoietic cell, cause the differentiation of the hematopoietic cells and induce the apoptosis of the hematopoietic cells.

Abstract
BACKGROUND AND OBJECTIVE In children it is very important to optimize PBPC harvesting and to reduce the number of leukaphereses per patient. The value of pre-apheresis peripheral blood CD34+ cell concentration as a predictor of PBPC yield was studied in 23 pediatric patients with hematologic and non-hematologic malignancies in order to optimize duration of PBPC collection. DESIGN AND METHODS The patients underwent 25 stem-cell mobilization episodes with G-CSF alone and 40 large-volume leukapheresis procedures. Peripheral blood and harvested CD34+ cell concentrations were analyzed by means of flow cytometry. RESULTS Using linear regression analysis, a highly significant correlation was found between the peripheral blood CD34+ cell count and the CD34+ cells/kg patient body weight collected on the apheresis day (r = 0.826, p = 0.0001). The results indicate that at least 1 x 10(6)/kg CD34+ cells can be harvested during one leukapheresis procedure in all patients if the pre-apheresis blood CD34+ cell count is > or = 30/microL and a CD34+ cell target of > or = 5 x 10(6)/kg is achieved in at least 80% of patients if this value is > or = 50 CD34+ cells/microL processing a median blood volume of 438.7 mL/kg (range, 207-560) over a median time of 232.5 minutes (range, 182-376). INTERPRETATION AND CONCLUSIONS Our results suggest that the number of CD34+ cells harvested in a single large-volume leukapheresis can be predicted from the measurement of peripheral blood CD34+ cell concentration on the collection day.

Abstract
We conducted a double retroviral vector (RV) gene marking trial to test for the possible contribution to relapse of follicular non-Hodgkin's lymphoma (FNHL) cells present in bone marrow (BM) and peripheral blood (PB) grafts used for hematopoietic reconstitution of patients undergoing myelaoblative chemotherapy and autologous transplant. CD34 positive selection using the CellPro Ceprate CD34 column was performed on PB mononuclear cells obtained after cyclophosphamide/G-CSF mobilization. CD34 positive cells were exposed for 4-6 hours to the LNL6 or G1 Na RV in the absence of growth factors or stromal monolayers. One week later, BM mononuclear cells were similarly processed. Patients then received total body irradiation (TBI), cyclophosphamide, and etoposide followed by infusion of both PB and BM CD34 positive cells. Semiquantitative Southern blot analysis of DNA t(14;18) amplification products showed approximately a three log reduction in t(14;18) positive cells after CD34 positive selection. The first patient showed evidence of engraftment with RV positive BM and PB cells for 9 months. He relapsed one year after transplant. At relapse, one year after transplant, he had lost evidence of RV positive cells in ficolled mononuclear BM and PB cells as well as in CD19 positive cells. The second and third patients showed evidence of engraftment with RV positive cells up to 9 and 6 months post BMT respectively. The second and third patients are still in clinical remission. Our results demonstrate engraftment of RV transduced hematopoietic cells in the PB and BM for up to 9 months.

Abstract
Ad.CMV-CD is a replication incompetent adenoviral vector carrying a cytomegalovirus (CMV)-driven transcription unit of the cytosine deaminase (CD) gene. The CD transcription unit in this vector catalyzes the deamination of the nontoxic pro-drug, 5-fluorocytosine (5-FC), thus converting it to the cytotoxic drug 5-fluorouracil (5-FU). This adenoviral vector prodrug activation system has been proposed for use in selectively sensitizing breast cancer cells, which may contaminate collections of autologous stem cells products from breast cancer patients, to the toxic effects of 5-FC, without damaging the reconstitutive capability of the normal hematopoietic cells. This system could conceivably kill even the nondividing breast cancer cells, because the levels of 5-FU generated by this system are 10 to 30 times that associated with systemic administration of 5-FU. The incorporation of 5-FU into mRNA at these high levels is sufficient to disrupt mRNA processing and protein synthesis so that even nondividing cells die of protein starvation. To test if the CD adenoviral vector sensitizes breast cancer cells to 5-FC, we exposed primary explants of normal human mammary epithelial cells (HMECs) and the established breast cancer cell (BCC) lines MCF-7 and MDA-MB-453 to the Ad.CMV-CD for 90 minutes. This produced a 100-fold sensitization of these epithelial cells to the effects of 48 hours of exposure to 5-FC. We next tested the selectivity of this system for BCC. When peripheral blood mononuclear cells (PBMCs), collected from cancer patients during the recovery phase from conventional dose chemotherapy-induced myelosuppression, were exposed to the Ad.CMV-CD for 90 minutes in serum-free conditions, little or no detectable conversion of 5-FC into 5-FU was seen even after 48 hours of exposure to high doses of 5-FC. In contrast, 70% of 5-FC was converted into the cytotoxic agent 5-FU when MCF-7 breast cancer cells (BCCs) were exposed to the same Ad.CMV-CD vector followed by 5-FC for 48 hours. All of the BCC lines tested were shown to be sensitive to infection by adenoviral vectors when exposed to a recombinant adenoviral vector containing the reporter gene betagalactosidase (Ad.CMV-betagal). In contrast, less than 1% of the CD34-selected cells and their more immature subsets, such as the CD34+CD38- or CD34(+)CD33- subpopulations, were positive for infection by the Ad.CMV-betagal vector, as judged by fluorescence-activated cell sorting (FACS) analysis, when exposed to the adenoviral vector under conditions that did not commit the early hematopoietic precursor cells to maturation. When artificial mixtures of hematopoietic cells and BCCs were exposed for 90 minutes to the Ad.CMV-CD vector and to 5-FC for 10 days or more, a greater than 1 million fold reduction in the number of BCCs, as measured by colony-limiting dilution assays, was observed. To test if the conditions were damaging for the hematopoietic reconstituting cells, marrow cells collected from 5-FU-treated male donor mice were incubated with the cytosine deaminase adenoviral vector and then exposed to 5-FC either for 4 days in vitro before transplantation or for 14 days immediately after transplantation in vivo. There was no significant decrease in the reconstituting capability of the male marrow cells, as measured by their persistence in female irradiated recipients for up to 6 months after transplantation. These observations suggest that adenovirus-mediated gene transfer of the Escherichia coli cytosine deaminase gene followed by exposure to the nontoxic pro-drug 5-FC may be a potential strategy to selectively reduce the level of contaminating BCCs in collections of hematopoietic cells used for autografts in breast cancer patients.

Abstract
HLA-B14 serological subtyping is very limited probably due to the internal position of the unique amino acid residue that differentiates B64 and B65 molecules. In order to carry out an accurate B14 subtyping we have designed a semi-nested PCR-SSP procedure that can differentiate B*1401 and B*1402 in any HLA-A, -B or -C antigen combination. A panel of 133 B14-positive and 31 B14-negative healthy and unrelated Spanish individuals were studied. Additionally, 45 B14-bearing haplotypes (-A,-B,-C,-DRB1,-DRB3/DRB4/DRB5,-DQA1,- DQB1) were available through family studies. The relative frequencies of HLA-B14 subtypes were 74% for B*1402 and 26% for B*1401, in agreement with those found in other Central European populations, but differing from those in Wales, where the relative presence of B64 goes to 41%. A total of 11/17 and 18/28 different haplotypes for B*1401 and B*1402, respectively, were identified. Both alleles showed the strongest association to Cw8 (43/45), indicating a primary ancestral B14-Cw8 association. However, B14 subtypes evidenced very distinguishable haplotype distributions. B*1401 is strongly associated with the common HLA class II haplotype DRB1*0701-DQA1*0201-DQB1*02 (13/17), while B*1402 is mainly associated to DRB1*0102 (16/28). Three major haplotypes were identified: A32-Cw8-B*1401-DR7-DQ2 (5/17), A33-Cw8-B*1402-DRB1*0102-DQ5 (5/28) and A2-Cw8-B*1402-DRB1*0102-DQ5 (5/28).

Abstract
The large majority of childhood B-precursor cell acute lymphoblastic leukaemia cases present IgH and TCRdelta gene rearrangements. These rearrangements have been widely used as specific markers for monitoring minimal residual disease. However, their prognostic value still remains unclear. In order to determine whether IgH and TCRdelta gene rearrangements have any influence on relapse and event-free survival (EFS), we analysed the clinical impact of these genetic characteristics in 51 B-precursor acute lymphoblastic leukaemia patients. 46/51 patients (90.2%) showed IgH gene rearrangements by Southern blot and/or polymerase chain reaction (PCR) analysis. No statistically significant associations were found between IgH gene rearrangement pattern and age, sex, WBC count, immunophenotype, risk factor, relapse or EFS. 27/41 patients (66%) showed Vdelta2Ddelta3 recombination by Southern blot and/or PCR analysis. At a median follow-up of 53 months the estimated 5-year EFS probability was 78 +/- 3% for the whole group. The EFS probability among patients with a Vdelta2Ddelta3 recombination pattern in the TCRdelta locus was 90 +/- 3%, whereas for patients without Vdelta2Ddelta3 recombination was 39 +/- 13% (P < 0.005). IgH rearrangement patterns do not appear to influence relapse or EFS probability. However, TCRdelta gene rearrangement patterns have a relevant impact on the relapse rate and the EFS probability. Patients with Vdelta2Ddelta3 recombination have better clinical outcome than patients without this recombination, independent of any other prognostic factors.

Abstract
The 3' flanking region of the interleukin-6 gene is polymorphic due to the existence of a hyper-variable region consisting of a number of A + T rich variable repeated DNA sequences (VNTR). We used specific primers to amplify this particular VNTR system by PCR in 222 unrelated normal Spaniards from Madrid, Spain. A model of inheritance comprising of five different allele classes was proposed and frequencies evaluated as follows: B4, 0.635; B3.1, 0.029; B3, 0.270; B2, 0.038; B1, 0.027. Also, examples of inheritance of mendelian microheterogeneity are shown. Heterozigosity index was calculated (H = 0.5) and no departure from Hardy-Weinberg equilibrium was observed (chi 2 = 0.091, d. f. 1, p > 0.75).

Abstract
We report the first case of T-cell gamma delta+ hepatosplenic malignant lymphoma in childhood. Tumour-specific oligoprobes were developed against the single V1-J1 rearrangement of the delta T-cell receptor (TCR) gene in order to perform minimal residual disease (MRD) studies. Molecular analysis in serial bone marrow samples proved to be of predictive value concerning the clinical outcome. Clonotypic DNA was not detected in peripheral blood during the course of the disease until a refractory terminal leukaemic phase took place 18 months after the diagnosis. This case demonstrates the usefulness of MRD studies to monitor the course of disease in at least some subsets of peripheral T-cell lymphomas.
