Manual measurement and manipulation of the cell surface requires access to the cells, usually in an open chamber. Temperature-controlled chambers or stage inserts are preferred for maintaining physiological activity during the experiment. For example, heated culture dishes with coverslip glass bottoms (Bioptechs) permit high-resolution fluorescence microscopy of living cells during force application. - [Read Chambers for Examination of Live Cells under Mechanical Stress Protocol]
Protocol describes how to set up microdrop cultures to produce embryos which can then be used for making chimeras. The microdrop culture should be set up several hours to 1 day before the experiment to permit temperature and gas equilibration. - [Read Setting Up Microdrop Cultures Protocol]
Two distinct modes of cell death, apoptosis and necrosis, can be distinguished on the basis of differences in
morphological, biochemical, and molecular changes occurring in the dying cells. Report the development of flow cytometric techniques that permit concomitant detection of apoptosis and cellular DNA content or BrdU content analysis. - [Read The Use of Flow Cytometry for Concomitant Detection of Apoptosis and Cell Cycle Analysis]
