Why humans have puzzle-shaped cells

The shapes of these cells are puzzling. They have wavy edges and protrusions that fit together a bit like puzzle pieces. But what is it for? New research looking at the lymph capillary cells, found throughout human tissues, has determined exactly how these tiny vessels are able to let fluid and immune cells pass through between them while also being strong enough to resist rupturing under pressure.
