    Methods for Synchronizing Cells at Specific Stages of the Cell Cycle The protocols presented here describe procedures used to synchronize cells in various stages of the cell cycle (Fig. 8.3.1). Synchronization is particularly useful for investigating a particular cell cycle–regulated event or preparing cells for extraction of transient factors whose expression is dependent on cell cycle stage. Exponentially growing cultures are generally asynchronous; i.e.‚ each cell progresses through the cell

    have the remarkable potential to develop into many different cell types in the body. Stem cells are distinguished from other cell types by two important characteristics. First‚ they are unspecialised cells capable of renewing themselves through cell division‚ sometimes after long periods of inactivity. Second‚ under certain physiologic or experimental conditions‚ they can be induced to become tissue‚ or organ-specific‚ cells with special functions. In some organs‚ such as the gut and bone marrow‚ these
