Knee and hip intra-articular adipose tissues (IAATs) compared with autologous subcutaneous adipose tissue: a specific phenotype for a central player in osteoarthritis.

Compared with subcutaneous adipose tissue (SCAT), infrapatellar fat pad (IFP), the main knee intra-articular adipose tissue (IAAT), has an inflammatory phenotype in patients with osteoarthritis (OA). We phenotyped suprapatellar fat pad (SPFP) and hip acetabular fat pad (AFP), two other IAATs, to determinate the unique signature of IAATs compared with SCAT.

The effect of dimethyl sulfoxide on hepatic differentiation of mesenchymal stem cells.

Adipose tissue-derived mesenchymal stem cells (AT-MSCs) are suitable choices in autologous stem cell treatment of liver-associated diseases due to their hepatic differentiation potential. Dimethyl sulfoxide (DMSO) is an amphipathic molecule with potential of delivering both lipophilic and hydrophilic agents into cells, also a common cryoprotectant for freezing of the cells. DMSO was used in some protocols for induction of AT-MSCs towards hepatocyte like cells. However, the effect of DMSO on hepatogenic differentiation of AT-MSCs were not surveyed, previously. In the present study, we aimed at evaluation of the effect of DMSO on differentiation of AT-MSCs into hepatic lineage.

The use of a polyelectrolyte fibrous scaffold to deliver differentiated hMSCs to the liver.

Liver transplantation as a therapy for liver failure is often hampered by a shortage of donor tissue. The delivery of liver-differentiated human mesenchymal stem cells (hMSCs) is a potential therapy to aid in liver regeneration. In this study, an RGD-modified chitosan-alginate polyelectrolyte complex (PEC) fibrous non-woven scaffold was employed to deliver differentiated hMSCs in vivo. Bone marrow-derived hMSCs were differentiated in vitro by a combination of extracellular matrix (ECM) and conditioned medium and seeded onto the RGD-modified chitosan-alginate fibrous scaffolds. The cell/scaffold construct was then implanted into the livers of a rat model, where 70% of the liver had been removed. Post-implantation analysis of the cell/scaffold constructs showed positive periodic acid-Schiff (PAS) staining for glycogen, and expression of the hepatic markers, AFP, CK19, CK18, albumin, HNF-3beta and MRP-2 by immunofluorescence labeling. In addition, human albumin was detectable in the rat serum by spot blot. These findings demonstrated that the RGD-modified chitosan-alginate fibrous scaffold was useful for delivering transdifferentiated hMSCs into the liver and maintaining the differentiated phenotype of the cells.

The differentiation of hepatocyte-like cells from monkey embryonic stem cells.

Embryonic stem cells (ESC) hold great potential for the treatment of liver diseases. Here, we report the differentiation of rhesus macaque ESC along a hepatocyte lineage. The undifferentiated monkey ESC line, ORMES-6, was cultured in an optimal culture condition in an effort to differentiate them into hepatocyte-like cells in vitro. The functional efficacy of the differentiated hepatic cells was evaluated using RT-PCR for the expression of hepatocyte specific genes, and Western blot analysis and immunocytochemistry for hepatic proteins such as alpha-fetoprotein (AFP), albumin and alpha1-antitrypsin (alpha1-AT). Functional assays were performed using the periodic acid schiff (PAS) reaction and ELISA. The final yield of ESC-derived hepatocyte-like cells was measured by flow cytometry for cells that were transduced with a liver-specific lentivirus vector containing the alpha1-AT promoter driving the expression of green fluorescence protein (GFP). The treatment of monkey ESC with an optimal culture condition yielded hepatocyte-like cells that expressed albumin, alpha1-AT, AFP, hepatocyte nuclear factor 3beta, glucose-6-phophatase, and cytochrome P450 genes and proteins as determined by RT-PCR and Western blot analysis. Immunofluorescent staining showed the cells positive for albumin, AFP, and alpha1-AT. PAS staining demonstrated that the differentiated cells showed hepatocyte functional activity. Albumin could be detected in the medium after 20 days of differentiation. Flow cytometry data showed that 6.5 +/- 1.0% of the total differentiated cells were positive for GFP. These results suggest that by using a specific, empirically determined, culture condition, we were able to direct monkey ESC toward a hepatocyte lineage.

Quantitative proteomic signature of liver cancer cells: tissue transglutaminase 2 could be a novel protein candidate of human hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common diseases worldwide, with extremely poor prognosis due to failure in diagnosing it early. Alpha-fetoprotein (AFP) is the only available biomarker for HCC diagnosis; however, its use in the early detection of HCC is limited, especially because about one-third of patients afflicted with HCC have normal levels of serum AFP. Thus, identifying additional biomarkers that may be used in combination with AFP to improve early detection of HCC is greatly needed. A quantitative proteomic analysis approach using stable isotope labeling with amino acids in cell culture (SILAC) combined with LTQ-FT-MS/MS identification was used to explore differentially expressed protein profiles between normal (HL-7702) and cancer (HepG2 and SK-HEP-1) cells. A total of 116 proteins were recognized as potential markers that could distinguish between HCC and normal liver cells. Certain proteins, such as AFP, intercellular adhesion molecule-1 (ICAM-1), IQ motif containing GTPase activating protein 2 (IQGAP2), claudin-1 (CLDN1) and tissue transglutaminase 2 (TGM2), were validated both in multiple cell lines and in 61 specimens of clinical HCC cases. TGM2 was overexpressed in some of the AFP-deficient HCC cells (SK-HEP-1 and Bel-7402) and in about half of the tumor tissues with low levels of serum AFP (17/32, AFP-negative HCC). Trace amounts of TGM2 were found to be expressed in the samples with high serum AFP (26/29, AFP-positive HCC). Moreover, TGM2 expression in liver tissues showed an inverse correlation with the level of serum AFP in HCC patients. Notably, TGM2 existed in the supernatant of the AFP-deficient SK-HEP-1, SMMC-7721 and HLE cells, and it was found to be induced in AFP-producing cells (HepG2) by specific siRNA silence assay. Serum TGM2 levels of 109 HCC patients and 42 healthy controls were further measured by an established ELISA assay; the levels were significantly higher in HCC patients, and they correlated with the histological grade and tumor size. These data suggest that TGM2 may serve as a novel histological/serologic candidate involved in HCC, especially for the individuals with normal serum AFP. These novel findings may provide important clues to identify new biomarkers of HCC and indirectly improve early detection of the disease.

Validating a custom multiplex ELISA against individual commercial immunoassays using clinical samples.

The measurement of multiple antigens in a single sample poses clinical and methodological challenges. Here we describe the validation of a multiplexed sandwich enzyme-linked immunosorbent assay (ELISA) array (microELISA) of nine antigens. The antigens tested simultaneously were: alpha-fetoprotein (AFP), prostate specific antigen (PSA), carcinoembryonic antigen (CEA), cancer antigen 125 (CA 125), CA 15-3, CA 19-9, beta-human chorionic gonadotropin (beta-hCG), luteinizing hormone (LH), and follicle stimulating hormone (FSH). At least 44 clinical samples were tested for each antigen. microELISA results for the nine antigens were then compared with clinical laboratory results obtained for the same antigens in individual chemiluminescent immunoassays. The microELISA had a coefficient of variation (cv) of 7.3% within an assay and 12.6% for assays run at different times. A statistical comparison of results from the microELISA with results from the clinical laboratory showed that the assays had correlation coefficients ranging from 0.99 to 0.76, and Deming regression demonstrated that four of the nine assays were high-quality assays and not statistically different to the individual assays. To determine if the differences in the assays were due to methodology, the microELISA was also compared with conventional ELISAs using identical antibodies and reagents. Deming regression demonstrated that five of the eight assays were high-quality, indicating that a poor correlation between a microELISA and an individual immunoassay are partly due to antibody differences.
