How are Extracellular Signals Studied in Histology?
Histologists use various techniques to study extracellular signals, including:
Immunohistochemistry: This technique involves using antibodies to detect specific proteins or signaling molecules in tissue sections. Fluorescence microscopy: Fluorescent tags are used to visualize signaling molecules and pathways in cells and tissues. In situ hybridization: This method allows for the localization of specific nucleic acid sequences within tissue sections, providing insights into gene expression related to signaling pathways.
