The genes regulating maintenance of cellular protein location are differentially expressed in porcine epithelial oviductal cells during longterm in vitro cultivation

fertilization, our aim was to gain a better insight into genetic changes that underlie these cells’ function. We established a long-term primary culture of porcine OECs and performed microarray analysis, checking gene expression in specific time periods. Our results revealed a set of genes belonging to “maintenance of location”, “maintenance of protein location in cell” and “maintenance of protein location” that were differentially expressed, indicating that they may be possible marker genes of biochemical and morphological changes in OECs.

Simple lipoaspirate washing using a coffee filter

Abstract

Background: Lipoaspirate contains noxious substances derived from liposuction. Therefore, extensive washing is recommended before the lipoaspirate is processed further for culture or fat grafting. Washing a small amount of lipoaspirate may not pose a problem, but washing a large volume of lipoaspirate may be cumbersome, time consuming, and requires a lot of phosphate buffered saline (PBS).

Objective: To introduce a simple method for lipoaspirate washing using fine-mesh stainless-steel tea or coffee filter, a small tea spoon, and a porcelain bowl.

Methods: The filter was used to collect the adipose tissue fragments. Further washing of the fragments was achieved by soaking the adipose tissue containing filter in a PBS containing porcelain bowl and stirring using a small tea spoon to transfer the contaminating materials to the PBS. Enzymatic processing to dissociate the cells from the tissue and primary cultures was conducted as usual in MesenCult.

Results: Using the equipment mentioned above, the adipose tissue fragments were readily separated from the blood, free lipids, anesthetics, and other noxious material in the liquid portion. This simple method saves time and PBS compared with previously described methods. Further enzymatic processing produced sufficient cells to be cultured, and culture results showed plastic adherent cells on day 2 that became confluent on day 6.

Conclusion: Lipoaspirate washing using a fine mesh stainless steel filter is time saving and produced cells that grow well in MesenCult.

Review Article. Technical aspects of oxygen level regulation in primary cell cultures: A review

Abstract

Oxygen (O2) is an essential element for aerobic respiration. Atmospheric concentration of O2 is approximately 21%. Mammalian cells, however, are generally adapted to O2 levels much lower than atmospheric conditions. The pericellular levels of O2 must also be maintained within a fairly narrow range to meet the demands of cells. This applies equally to cells in vivo and cells in primary cultures. There has been growing interest in the performance of cell culture experiments under various O2 levels to study molecular and cellular responses. To this end, a range of technologies (e.g. gas-permeable technology) and instruments (e.g. gas-tight boxes and gas-controlled incubators) have been developed. It should be noted, however, that some of these have limitations and they are still undergoing refinement. Nevertheless, better results should be possible when technical concerns are taken into account. This paper aims to review various aspects of O2 level adjustment in primary cell cultures, regulation of pericellular O2 gradients and possible effects of the cell culture medium.

The Effect of Laurel Leaf Extract Against Toxicity Induced by 2,3,7,8-Tetrachlorodibenzo-P-Dioxin in Cultured Rat Hepatocytes

The Effect of Laurel Leaf Extract Against Toxicity Induced by 2,3,7,8-Tetrachlorodibenzo-P-Dioxin in Cultured Rat Hepatocytes

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a very toxic environmental pollutant that raises great public concern about its impact on human health. Recent studies indicate that laurel leaf extract exhibits antioxidant properties that can counter the toxic effects of certain compounds in the liver. The aim of this study was to assess how effective LE is against the toxicity of TCDD in a primary culture of rat hepatocytes. The extract (50 mg L-1, 100 mg L-1, and 200 mg L-1) was added to cultures alone or with TCDD (1.61 mg L-1 and 3.22 mg L-1) for 48 hours. Cell viability was measured using the [3-(4,5-dimethyl-thiazol-2-yl) 2,5-diphenyltetrazolium bromide] (MTT) assay and the lactate dehydrogenase (LDH) cytotoxicity assay, while oxidative damage was assessed by measuring total antioxidant capacity (TAC) and total oxidative stress (TOS). DNA damage was also analysed using the micronucleus (MN) assay of the cultured hepatocytes. TCDD alone lowered, and laurel extract had no effect on cell viability. TCDD also increased TOS and significantly decreased TAC. It significantly increased the frequency of micronucleated hepatocytes in a dose-dependent manner. In cultures exposed to LE alone, TOS did not change and TAC significantly increased in a dose-dependent manner. Added to TCDD, laurel countered its toxic effects and showed protective effects against TCDD-mediated DNA damage. This points to the therapeutic potential of laurel against TCDD toxicity in the liver.
