1. Structural Support: It provides a stable platform for cells to adhere to, maintaining tissue integrity. 2. Filtration: In tissues like the kidney glomerulus, the basal lamina acts as a filtration barrier, controlling the passage of molecules. 3. Cell Migration: During processes such as wound healing and embryonic development, the basal lamina guides cell movement. 4. Tissue Repair: It plays a role in tissue repair by regenerating the extracellular matrix. 5. Signaling: Through interactions with cell surface receptors, it influences cell differentiation, proliferation, and survival.
