Abstract
BACKGROUND increased serum alpha fetoprotein (AFP) levels are often found in patients with advanced hepatocellular carcinoma (HCC). Cluster Differentiation 44 (CD44) and CD90 are stem cell biomarkers that have been assumed as the early HCC markers and associated with onset and progressivity of HCC. The study related to HCC stem cell has not been available in Indonesia. The present study aimed to evaluate the expression of cancer stem cell markers (CD44, CD90) and AFP levels in patients with advanced liver disease. METHODS an observational study was conducted in 41 patients with chronic hepatitis B and/or C infection, liver cirrhosis, and HCC at dr. Saiful Anwar General Hospital. CD44 and CD90 expressions were measured with flow cytometry, and AFP serum levels with ELISA. Data on patient characteristics were evaluated using bivariate and multivariate statistical analysis (One-way ANOVA, Mann-Whitney, Chi-Square, Kruskal-Wallis). Data of CD44, CD90 and AFP were analyzed using Kruskal Wallis test with a significance value of p<0.05, and diagnostic power was analyzed using receiver operating characteristic (ROC). RESULTS the subjects of our study were 16 patients with chronic hepatitis, 15 patients with liver cirrhosis, and 10 patients with HCC. There was a significant difference regarding CD44+CD90+ and AFP among those three groups (p=0.001; p=0.000) specifically in chronic hepatitis compared to liver cirrhosis (p=0.002; p=0.000) and HCC (p=0.002; p=0.000) respectively. ROC analysis showed the best diagnostic power for the combination of CD44+CD90+ and AFP (AUC=0.981; p=0.000). CONCLUSION there are higher expressions of CD44+CD90+ and serum AFP levels in patients with HCC compared to the other two groups (those with chronic hepatitis and liver cirrhosis). The combination of both parameters has the best diagnostic power of HCC.

Abstract
OBJECTIVE To investigate the changes in circulating bone marrow stem cells in pregnant rabbits after AMI (AMI) and their relationship with estradiol. METHODS Three groups of rabbits were used, namely pregnancy and AMI group, AMI group without pregnancy, and sham operation group with pregnancy. The ratio of CD90(+) cells in the peripheral blood was determined with flow cytometry in all the rabbits, and serum estradiol level measured. Four weeks after AMI, hemodynamic measurements were carried out. The morphological changes of the myocardial tissues were examined with ImageJ 1.31. RESULTS AND CONCLUSION Four weeks after AMI, the two pregnancy groups showed a higher Left ventricular end systolic pressure(LVESP) and+dp/dtmax, lower left ventricular end-diastolic pressure (LVEDP) and -dp/dtmax and high levels of CD90(+) cells in peripheral blood than AMI group without pregnancy (P<0.01). The ratio of circulating CD90(+) cells increased gradually with gestational age and peaked at the end stage of pregnancy. After delivery the circulating CD90+ cell ratio decreased sharply, showing a significant correlation with serum estradiol level (r=0.725, P<0.01). Four weeks after AMI, the pregnancy group had smaller myocardial infarction (MI) volume than the non-pregnant group (22.17+/-6.34% vs 38.86+/-5.97%, P<0.05). Circulating bone marrow stem cells increased during pregnancy with gestational age and peaked at the end stage of pregnancy. Ten days after delivery, the stem cells resumed basically the normal level. The proportion of circulating bone marrow stem cells was significantly correlated with the level of serum estradiol during pregnancy, and mobilization of the bone marrow stem cells induced by acute ischemic event in pregnant rabbits was advanced. 4 weeks after AMI, the pregnant rabbits showed better heart contraction and diastolic function than the non-pregnant ones.

Abstract
A fetus diagnosed with X-linked chronic granulomatous disease was transplanted with Thy-1(+)CD34(+) cells of paternal origin. The transplant was performed at 14 weeks gestation by ultrasound guided injection into the peritoneal cavity. The fetus was delivered at 38 weeks gestation after an otherwise uneventful pregnancy. Umbilical cord blood was collected and used to determine the level of peripheral blood chimerism as well as levels of functional engrafted cells. Flow cytometry was used to detect donor leukocytes identified as HLA-A2(-)B7(+) cells, whereas recipient cells were identified as HLA-A2(+)B7(-) cells. No evidence of donor cell engraftment above a level of 0.01% was found. PCR was used to detect HLA-DRB1*15(+) donor cells among the recipient's HLA-DRB1*15(-) cells, but no engraftment was seen with a sensitivity of 1:1000. The presence of functional, donor-derived neutrophils was assessed by flow cytometry using two different fluorescent dyes that measure reactive oxygen species generated by the phagocyte NADPH oxidase. No evidence of paternal-derived functional neutrophils above a level of 0.15% was observed. Peripheral blood and bone marrow samples were collected at 6 months of age. Neither sample showed engraftment by HLA typing using both flow cytometry and PCR. Functional phagocytes were also not observed. Furthermore, no indication of immunological tolerance specific for the donor cells was indicated by a mixed lymphocyte reaction assay performed at 6 months of age. While there appears to be no engraftment of the donor stem cells, the transplant caused no harm to the fetus and the child was healthy at 6 months of age. Analyses of fetal tissues, obtained from elective abortions, revealed that CD3(+) T cells and CD56(+)CD3(-) NK cells are present in the liver at 8 weeks gestation and in the blood by 9 weeks gestation. The presence of these lymphocytes may contribute to the lack of donor cell engraftment in the human fetus.

Abstract
BACKGROUND AND OBJECTIVE CD34+ hematopoietic progenitor cells (HPCs) constitute a heterogeneous population both in size and in immunological features. Lack of CD38, HLA-DR and lineage committed antigens as well as the co-expression of Thy-1 (CDw90) and c-kit receptor (CD117), are able to identify the so-called stem cells. A flow cytometric study was carried out to investigate the co-expression of Thy-1 and c-kit receptors, both members of Ig superfamily adhesion molecules, involved in cell to cell and cell to stroma interactions, on bone marrow (BM), mobilized peripheral blood (PB) and human umbilical cord blood (HUCB) CD34+ HPCs. DESIGN AND METHODS Lysed whole blood from 15 BM, 25 mobilized PB and 25 HUCB samples were used to perform a five-dimensional flow cytometric evaluation of both CDw90 and CD117 on CD34+ cells. RESULTS Few CD34+ cells co-expressed Thy-1 antigen in all three compartments (BM: 11.2 +/- 7.2%; PB: 6.2 +/- 3.6%; HUCB: 6 +/- 2.9%; BM vs PB < 0.04; BM vs HUCB < 0.008; PB vs HUCB ns). c-kit receptor was detected on the majority of CD34+ HPCs, particularly in HUCB (HUCB: 80.7 +/- 8.2%; BM: 72.3 +/- 13.1%; PB: 64.2 +/- 17%; HUCB vs BM < 0.03; HUCB vs PB < 0.0001; BM vs PB ns). CD34+Thy-1+ and CD34+c-kit+ HPCs generally displayed HLA-DR antigen, as expression of early cell commitment. However, the most immature CD34+Thy-1+HLA-DR- (HUCB: 1 +/- 0.6%; BM: 0.4 +/- 03%; PB: 0.7 +/- 0.5%; HUCB vs BM < 0.0001; BM vs PB < 0.04; HUCB vs PB ns) and CD34+c-kit+HLA-DR- HPCs (HUCB: 6.5 +/- 4.4%; BM: 6.3 +/- 4.8%; PB: 2.2 +/- 1.8%; HUCB vs BM ns; BM vs PB < 0.0001; HUCB vs PB < 0.0001) were mainly detected in HUCB. Finally, the greatest percentage of CD34+Thy-1+c-kit+ cells was found in BM (6.9 +/- 4.1%) followed by leukapheretic samples (4.4% +/- 2.7) and then by HUCB (3.7 +/- 1.2%; BM vs PB ns; BM vs HUCB < 0.001; HUCB vs PB ns). INTERPRETATION AND CONCLUSIONS Since the blood release or HPCs is probably due to a perturbation of the adhesive interactions between these cells and the marrow stroma, the different pattern of Thy-1 and c-kit receptor expression on CD34+ HPCs found in the three hemopoietic compartments evaluated can lead to new knowledge about the mobilization kinetics in which the Ig superfamily adhesion molecules are involved.

Abstract
Repeated exposure to mercury causes various autoimmune effects in rats of the Brown Norway (BN) strain. Previous studies from our laboratory have shown that on day 15 of HgCl2 treatment BN rats exhibit a relative decrease in RT6.2+ T cells. At the same time, they produce high levels of autoantibodies to renal antigens and experience a membranous glomerulonephropathy. In contrast, Lewis (LEW) rats are resistant to autoimmunity caused by mercury and do not demonstrate a decrease in RT6+ cells after administration of HgCl2. In the present paper we provide novel information on the correlation between changes in RT6.2+ lymph node T cells and the production of autoantibodies to laminin 1, obtained by detailed kinetic studies of HgCl2-treated BN rats. We have confirmed a decrease in the percentage of RT6.2+ lymphocytes on day 15 of mercury treatment, despite a significant increase in the number of peripheral lymphocytes. No such changes were observed in LEW rats. We have determined that on day 15 the percentage decrease in RT6+ cells is evident in both RT6.2+CD4+ and RT6.2+CD8+ T cell subsets. Kinetic studies demonstrated that significant changes in the percentage of RT6.2+ cells are first observed by day 8 and continue through days 11 and 15. We have also observed a significant percent decrease in CD4+ T lymphocytes as well as an increase in CD4-CD8- cells. The dramatic increase in the percentage of these double negative cells at the level of peripheral lymphoid tissues does not appear to be due to higher thymic output, since there was a decrease in the percentage of TCR+Thy1+ cells, a phenotype that is associated with recent thymic emigrants. Finally, we have demonstrated that 100% of HgCl2-treated BN rats had circulating antibodies that reacted with both mouse and rat laminin 1, i.e. are autoantibodies to laminin 1. These autoantibodies were predominantly of the IgG1 and IgG2a isotype, possibly as the result of a polarized autoimmune response driven by Type 2 cytokines. A kinetic investigation showed that significant levels of IgG1 and IgG2a autoantibodies to laminin 1 were first presentin the circulation by day 11. The inverse correlation between levels of RT6.2+ T lymphocytes and autoantibodies to laminin 1 suggests that mercury may induce autoimmune responses in BN rats by its effects on these immunoregulatory cells.

Abstract
OBJECTIVE To estimate the amount of peripheral blood stem cells(PBSC) right during mobilization and determine the optimal time for PBSC collection. METHODS A serial measurement of circulating CD34+ Thy-1(+) cells were carried out during PBSC mobilization by chemotherapy and granulocyte colony stimulating factor(G-CSF) using dual-color direct immunofluorescence flow cytometry. Colony-culture in vitro was performed at the same time to evaluate the clonogenic capacity of the peripheral blood progenitor cells (PBPCs). RESULTS Circulating CD34+ Thy-1(+) cells, CD34+ cells and colony-forming cells increased by 48.6-, 50- and 53.1- fold, respectively, after mobilization. The peak levels were reached at 12 approximately 14 days after chemotherapy. The proportion of CD34+ cells and the candidate stem cells, CD34+ Thy-1(+) subset, in mononuclear cells (MNCs) exceeded baseline by 10.5- and 13.8- fold, respectively. The percentage of CD34+ cells coexpressing Thy-1 was highest in the earlist phase of mobilization. CONCLUSION PBSCs, especially primitive progenitor cells, increased significantly during mobilization with chemotherapy and G-CSF. Flow cytometric assay of circulating CD34 Thy-1(+) cells promptly provides a more reliable indicator for clinical collection of PBSC.

Abstract
Bone marrow and peripheral blood from 28 adult patients with acute myeloid leukemia (AML) were analyzed for the surface expression of the Thy-1 antigen by dual-colour flow cytometry. The Thy-1 antigen was expressed on greater than 5% of cells from seven patients with the proportions of Thy-1 positive cells ranging from 8.1% to 85.0%. The CD34+ Thy-1+ phenotype was present in all seven cases. The expression of Thy-1 on leukemia cells from patients with AML may need to be considered in the development of methods of normal stem cell isolation from these patients.

Abstract
Acute myeloid leukaemia (AML) is thought to be maintained by a small population of leukemic progenitor cells. To define the phenotype of such cells with long-term proliferative capacity in vitro and in vivo, we have used the production of leukemic clonogenic cells (CFU) after 2 to 8 weeks in suspension culture as a measure of these cells in vitro and compared their phenotype with that of cells capable of engrafting nonobese diabetic severe combined immune deficient (NOD/SCID) mice. Leukemic blast peripheral blood cells were evaluated for expression of CD34 and Thy-1 (CD90) antigens. The majority of AML blast cells at diagnosis lacked expression of Thy-1. Most primary CFU-blast and the CFU detected at up to 8 weeks from suspension cultures were CD34+/Thy-1-. AML cells that were capable of engrafting NOD/SCID mice were also found to have the CD34+/Thy-1- phenotype. However, significant engraftment was achieved using both CD34+/Thy-1- and CD34- subfractions from one AML M5 patient. These results suggest that while heterogeneity exists between individual patients, the leukemic progenitor cells that are capable of maintaining the disease in vitro and in vivo differ from normal hematopoietic progenitor cells in their lack of expression of Thy-1.

Abstract
Donor and host T cells were distinguished by T cell antigen marker Thy-1 isotype and cytoplasmic isozyme Gpi-1 in this study of bone marrow transplantation between congenic mice. During the first 3-6 weeks after irradiation and marrow transfer, percentages of cells bearing the donor Thy-1 isotype in the periphery are much lower than percentages of T cells bearing the donor Gpi-1 marker. Apparently a population of Thy-1- donor T cells exists for several weeks after bone marrow transplantation. Further study showed that this population of CD3+, Thy-1- donor T cells expressed CD4+ or CD8+ and was found in peripheral blood and spleen but not in the thymus. This finding suggests their extrathymic origin.

Abstract
In rats, RT6 and CD45RC are expressed by mature peripheral T cells. The underrepresentation of T cells expressing these markers in the T lymphocytopenic BB rat might therefore be a reflection of a relatively immature T cell population. With the use of Thy-1 as a marker for recent thymic migrants, it was demonstrated that BB rats indeed have a phenotypically less mature T cell population than age-matched control rats. However, this could not account for the reduced percentages of RT6+ and CD45RC+ T cells, as these were also decreased among mature Thy-1- T cells of BB rats. Although relatively overrepresented, absolute numbers of Thy-1+ T cells were reduced in BB rats. Absolute numbers of mature Thy-1- T cells were also reduced in BB rats, but to a much larger degree than would proportionally be expected. Our findings taken together led us to conclude that both reduced thymic output and a defect in peripheral expansion are involved in the T lymphocytopenia of BB rats.
