P63. Autologous tumour cells and SW742 allogeneic cell line have comparable stimulating effect on PBMCs of gastrointestinal malignant patients in vitro
نویسندگان
چکیده
Materials and methods Malignant autologous epithelial cells of 10 colorectal carcinoma patients were separated by cell culture procedures. Peripheral blood mononuclear cells (PBMCs) were stimulated with their mitomycin treated autologous tumour cells or allogeneic SW742 colorectal carcinoma cell line. The expression of CD3, CD56, NKG2D and NKp44 were detected with flowcytometry and reverse transcriptionPCR. NK activity of PBMCs against K562 target cell line was measured by MTT colorimetric assay.

Mesenchymal Stem Cells Do Not Suppress Lymphoblastic Leukemic Cell Line Proliferation
Background: Several studies have demonstrated the immunosuppresive effects of mes-enchymal stem cells (MSCs) in allogeneic or mitogenic interactions. Cell-cell contact inhibition and secretion of suppressive soluble factors have been suggested in this re-gard. Objective: To investigate if adipose derived MSCs could inhibit Jurkat lym-phoblastic leukemia T cell proliferation during coculture. Me...
متن کاملAntiproliferative Effect of Aspirin on Colorectal Cancer Cell Line
Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as Aspirin may have anticancer properties, and can be effective as a novel strategy for the treatment of colorectal cancer (CRC). The aim of this study was to assess the cytotoxic effects of Aspirin drug in CRC cell lines compared with Oxaliplatin drug in vitro. Methods: Cell viability was assessed after treatment of SW742 and SW48...
متن کاملEffect of Myeloma-Derived Microparticles on in Vitro Proliferation and Viability of Alloimmune Human Peripheral Blood Mononuclear Cells
Background: Microparticles (MPs) are small vesicles released from the cell membrane. Accordingly, these contain active molecules to mediate biological processes, including cell proliferation and cell cycle progression. The fusion of myeloma cell lines with immunized B lymphocytes is a critical step of hybridoma technology. MPs modulate lymphoproliferation, thereby facilitating B cell expansion ...
متن کاملEffect of Anti-CD3/CD28 Dynabeads and Allogeneic PBMCs on Expansion of Anti-MUC1 Chimeric Receptor T Cells
Background and purpose: In recent years, immunotherapy using chimeric antigen receptor T cells (CAR T cells) has been considered as a novel and promising treatment for some diseases, especially cancer. The CAR T cell production is a multi-step, complex, time-consuming, and costly process. One of the most important steps in production of CAR T cells is expansion of these cells at appropriate num...

Neospora caninum is a coccidian protozoan parasite which is a major cause of bovine abortions and neonatal mortality in cattle, sheep, goat and horse. Occasionally, cultured cells are used for isolation and multiplication of the agent in vitro with several purposes. In this study the tachyzoite yields of N. caninum were compared in various cell cultures as the host cell lines. Among the cell cu...
