Histologists study cell growth using various techniques, including: - Microscopy: Light and electron microscopes are used to observe cell morphology and structure. - Histological Staining: Stains like hematoxylin and eosin (H&E) highlight different cellular components, aiding in the identification of growth patterns. - Immunohistochemistry: This technique uses antibodies to detect specific proteins involved in cell growth, providing insight into the molecular mechanisms at play.
