Cryopreservation of Cultured Plant Cells
Undifferentiated cell cultures of higher plants are important genetic resources used extensively in cytological, physiological, and molecular biological studies. The development of a reliable and cost-effective method for the maintenance of cultured cells is required to minimize the risk of losing cell lines to disease, contamination, and technical errors, as well as the risk of changes in morp...
متن کاملActivation of 2-aminofluorene by cultured plant cells.
Cultured tobacco plant cells activated 2-aminofluorene to an agent mutagenic to Salmonella typhimurium strain TA98. The plant activation of 2-aminofluorene is heat-inactivated and may not involve solely cytochrome P-450. The kinetics of activation demonstrated both time- and concentration-dependent responses.
متن کاملMeasuring NO production by plant tissues and suspension cultured cells.
We describe an inexpensive and reliable detector for measuring NO emitted in the gas phase from plants. The method relies on the use of a strong oxidizer to convert NO to NO2 and subsequent capture of NO2 by a Griess reagent trap. The set-up approaches the sensitivity for NO comparable to that of instruments based on chemiluminescence and photoacoustic detectors. We demonstrate the utility of o...
متن کاملConditioned Medium from Cultured Colorectal Cancer Cells Affects Peripheral Blood Mononuclear Cells Inflammatory Phenotype in Vitro
Background: Colorectal cancer (CRC) is the third most common cancer worldwide. Studies have indicated that immune cells and soluble factors play a key role in maintaining the balance between tumor-promoting inflammation and anti-tumor immunity. It has been shown that secreted cytokines from CRC cell lines could affect peripheral blood mononuclear cells (PBMCs), monocytes, and macrophages phenot...
متن کاملIncreased mir33 Expression in Expanded Hematopoietic Stem Cells Cultured on Adipose Stem Cells Feeder layer
Bachgroun: Hematopoietic stem cell derived from umbilical cord blood (UCB) has been used for regenerative medicine in hematological abnormalities. MicroRNAs are important regulators of gene expression that control both physiological and pathological processes such as development of tissue and cancer. Some studies have shown that miR-33, has a critical role in control of self-renewal cells. He...
