ASTM E1881-2012 用次级离子质谱法 (SIMS) 对细胞培养分析的标准指南
简介:5. Significance and UseTop Bottom 5.1 The presence of cell growth medium complicates a direct analysis of cells with SIMS. Attempts to wash out the nutrient medium results in the exposure of cells to unphysiological reagents that may also alter their chemical composition. This obstacle is overcome by using a sandwich freeze-fracture method (1). This cryogenic method has provided a unique way of sampling individual cells in their native state for SIMS analysis. 5.2 The procedure described here has been successfully used for imaging Na+ and K+ ion transport (3), calcium alterations in stimulated cells (4,5), and localization of therapeutic drugs and isotopically labeled molecules in single cells (6). The frozen freeze-dried cells prepared according to this method have been checked for SIMS matrix effects (7). Ion image quantification has also been achieved in this sample type (8). 5.3 The procedure described here is amenable to a wide variety of cell cultures and provides a way for studying the response of individual cells for chemical alterations in the state of health and disease and localization of isotopically-labeled molecules and theraputic drugs in cell culture models. 1.1 This guide provides the Secondary Ion Mass Spectrometry (SIMS) analyst with a cryogenic method for analyzing individual tissue culture cells growing in vitro. This guide is suitable for frozen-hydrated and frozen-freeze-dried sample types. Included are procedures for correlating optical, laser scanning confocal and secondary electron microscopies to complement SIMS analysis. 1.2 This guide is not suitable for cell cultures that do not attach to the substrate. 1.3 This guide is not suitable for any plastic embedded cell culture specimens. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM F895-2011 细胞培养及毒素屏蔽的标准试验方法
简介:This test method is useful for assessing the cytotoxic potential of new materials and formulations and as part of a quality control program for established medical devices and components. This test method assumes that assessment of cytotoxicity provides useful information to aid in predicting the potential clinical applications in humans. Cell culture methods have shown good correlation with animal assays and are frequently more sensitive to cytotoxic agents. This cell culture test method is suitable for incorporation into specifications and standards for materials to be used in the construction of medical devices that are to be implanted into the human body or placed in contact with tissue fluids or blood on a long-term basis. Some biomaterials with a history of safe clinical use in medical devices are cytotoxic. This test method does not imply that all biomaterials must pass this assay to be considered safe for clinical use (Practice F748).1.1 This test method is appropriate for materials in a variety of shapes and for materials that are not necessarily sterile. This test method would be appropriate in situations in which the amount of material is limited. For example, small devices or powders could be placed on the agar and the presence of a zone of inhibition of cell growth could be examined. 1.1.1 This test method is not appropriate for leachables that do not diffuse through agar or agarose. 1.1.2 While the agar layer can act as a cushion to protect the cells from the specimen, there may be materials that are sufficiently heavy to compress the agar and prevent diffusion or to cause mechanical damage to the cells. This test method would not be appropriate for these materials. 1.2 The L-929 cell line was chosen because it has a significant history of use in assays of this type. This is not intended to imply that its use is preferred, only that the L-929 is an established cell line, well characterized and readily available, that has demonstrated reproducible results in several laboratories. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and UseTop Bottom 4.1 This practice is useful for assessing cytotoxic potential both when evaluating new materials or formulations for possible use in medical applications, and as part of a quality control program for established medical materials and medical devices. 4.2 This practice assumes that assessment of cytotoxicity potential provides one method for predicting the potential for cytotoxic or necrotic reactions to medical materials and devices during clinical applications to humans. In general, cell culture testing methods have shown good correlation with animal assays and are frequently more sensitive to toxic moieties. 4.3 This cell culture test method is suitable for adoption in specifications and standards for materials for use in the construction of medical devices that are intended to be implanted in the human body or placed in contact with tissue, tissue fluids, or blood on a long-term basis. However, care should be taken when testing materials that are resorbable to be sure the method is applicable. 4.4 Since cells in this direct contact test method are not protected by an overlying agarose layer, they are more susceptible to potential mechanical damage imparted by the overlying test sample. Investigators wishing to evaluate the cytotoxic response of cells underlying the test sample should consider agarose-based methods similar to Test Method F895. Alternatively, depending on sample characteristics, extraction methods such as Practice F619 may also be considered. 1.1 This practice covers a reference method of direct contact cell culture testing which may be used in evaluating the cytotoxic potential of materials for use in the construction of medical materials and devices. 1.2 This practice may be used either directly to evaluate materials or as a reference against which other cytotoxicity test methods may be compared. 1.3 This is one of a series of reference test methods for the assessment of cytotoxic potential, employing different techniques. 1.4 Assessment of cytotoxicity is one of several tests employed in determining the biological response to a material, as recommended in Practice F748. 1.5 The L-929 cell line was chosen because it has a significant history of use in assays of this type.

ASTM F2997-2013 采用荧光图像分析量化祖细胞成骨培养钙沉积的标准实施规程
简介:5.1x00a0;In-vitro osteoblast differentiation assays are one approach to screen progenitor stem cells for their capability to become osteoblasts. The extent of calcified deposits or mineralized matrix that form in-vitro may be an indicator of differentiation to a functional osteoblast; however, gene expression of osteogenic genes or proteins is another important measurement to use in conjunction with this assay to determine the presence of an osteoblast. 5.2x00a0;This test method provides a technique for staining, imaging, and quantifying the fluorescence intensity and area related to the mineralization in living cell cultures using the non-toxic calcium-chelating dye, xylenol orange. The positively stained area of mineralized deposits in cell cultures is an indirect measure of calcium content. It is important to measure the intensity to assure that the images have not been underexposed or overexposed. Intensity does not correlate directly to calcium content as well as area. 5.3x00a0;Xylenol orange enables the monitoring of calcified deposits repeatedly throughout the life of the culture without detriment to the culture. There is no interference on subsequent measurements of mineralized area due to dye accumulation from repeated application (1).3 Calcified deposits that have been previously stained may appear brighter, but this does not impact the area measurement. Calcein dyes may also be used for this purpose (1) but require a different procedure for analysis than xylenol orange (i.e., concentration and filter sets) and are thus not included here. Alizarin Red and Von Kossa are not suitable for use with this procedure on living cultures since there is no documentation supporting their repeated use in living cultures without deleterious effects. 5.4x00a0;The test method may be applied to cultures of any cells capable of producing calcified deposits. It may also be used to document the absence of mineral in cultures where the goal is to avoid mineralization. 5.5x00a0;During osteoblast differentiation assays, osteogenic supplements are provided to induce or assist with the differentiation process. If osteogenic supplements are used in excess, a calcified deposit may occur in the cell cultures that is not osteoblast-mediated and thus is referred to as dystrophic, pathologic, or artifactual (2). For example, when higher concentrations of beta-glycerophosphate are used in the medium to function as a substrate for the enzyme alkaline phosphatase secreted by the cells, there is a marked increase in free phosphate, which then precipitates with Ca++ ions in the media to form calcium phosphate crystals independently of the differentiation status of the progenitor cell. Alkaline phosphatase production is associated with progenitor cell differentiation, and is frequently stimulated by dexamethasone addition to the medium, which enhances the formation of calcified deposits. These kinds of calcified/mineral deposits are thus considered dystrophic, pathologic, or artifactual because they were not initiated by a mature osteoblast. The measurement obtained by using this practice may thus result in a potentially false interpretation of the differentiation status of osteoprogenitor cells if used in isolation without gene or protein expression data (3,4). 5.6x00a............

简介:The presence of cell growth medium complicates a direct analysis of cells with SIMS. Attempts to wash out the nutrient medium results in the exposure of cells to unphysiological reagents that may also alter their chemical composition. This obstacle is overcome by using a sandwich freeze-fracture method (1). This cryogenic method has provided a unique way of sampling individual cells in their native state for SIMS analysis. The procedure described here has been successfully used for imaging Na+ and K+ ion transport (3), calcium alterations in stimulated cells (4,5), and localization of therapeutic drugs and isotopically labeled molecules in single cells (6). The frozen freeze-dried cells prepared according to this method have been checked for SIMS matrix effects (7). Ion image quantification has also been achieved in this sample type (8). The procedure described here is amenable to a wide variety of cell cultures and provides a way for studying the response of individual cells for chemical alterations in the state of health and disease and localization of isotopically-labeled molecules and theraputic drugs in cell culture models.1.1 This guide provides the Secondary Ion Mass Spectrometry (SIMS) analyst with a cryogenic method for analyzing individual tissue culture cells growing in vitro. This guide is suitable for frozen-hydrated and frozen-freeze-dried sample types. Included are procedures for correlating optical, laser scanning confocal and secondary electron microscopies to complement SIMS analysis.1.2 This guide is not suitable for cell cultures that do not attach to the substrate.1.3 This guide is not suitable for any plastic embedded cell culture specimens.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
