Histologists use a variety of techniques to study cell population dynamics. Histological staining methods, such as Hematoxylin and Eosin (H&E) staining, allow for the visualization of different cell types and structures within a tissue. Immunohistochemistry uses antibodies to detect specific proteins, providing insights into cell differentiation and function. Advanced imaging techniques, such as confocal microscopy, enable detailed examination of cell behavior in live tissues.
