The disadvantages of histology and histological staining include: Preparation of the slides using the paraffin technique can be time-consuming; frozen slides are faster to prepare, but this can affect the resolution, especially when using light microscopy. A differentiation stage-specific promoter can be included, which becomes activated when a stem cell differentiates into other cells, and then real-time imaging of a fluorescent protein, and hence . Table 5. The microscopic observation is that it helps in identifying the cell through the color change. Differential staining allows one to differentiate G+ from G- cells, whereas simple staining only shows cell size and morphology. It use along with the Haematoxylin in staining to demonstrate the cytoplasm of different types of cells,connective tissues, muscles, RBCs etc. The most basic reason that cells are stained is to enhance visualization of the cell or certain cellular components under a microscope.
