Which epidermal component forms cell-to-cell junctions that bind keratinocytes together?

Desmosomes are specialized intercellular junctions that anchor adjacent keratinocytes in the epidermis, linking their keratin networks across cells to form a strong, cohesive layer that resists mechanical stress. Keratinocytes are the main skin cells that produce keratin themselves; Langerhans cells are immune cells in the epidermis; and the stratum germinativum (basal layer) is the living layer where keratinocytes originate and proliferate. The desmosomes’ role in binding keratinocytes together makes them the correct component for cell-to-cell junctions in the epidermis.
