This study investigates the distribution of intermediate filaments such as vimentin and cytokeratin in cellular structures, focusing on desmosomes situated in intercellular spaces. Using DAPI overlay for nucleus visualization, we analyzed fluorescence intensity through double staining techniques. The presence of desmin was also explored within the context of antibody staining. Results highlight the importance of these structures in cell integrity and communication, revealing key insights into their roles in cellular architecture.
