So laminin came up and the structure of it is interesting. Looks like the caduceus, cross, unfolded tesseract, sword, and probably more.

Laminins are high-molecular weight (~400kDa) proteins of the extracellular matrix. They are a major component of the basal lamina (one of the layers of the basement membrane), a protein network foundation for most cells and organs. The laminins are an important and biologically active part of the basal lamina, influencing cell differentiation, migration, and adhesion.
