The fatty membranes of cells are capable of self-repair using a mechanism that involves Ca2+-dependent exocytosis.

"Self-repair: Our bodies are packages within packages. Every cell has a fatty membrane that self-assembles when placed in water, then reassembles when a breach occurs. Imagine a polymer wrapper that would heal when ripped during use, but would eventually decompose when placed in a compost heap." (Biomimicry Guild unpublished report)
