What is the shape of RBC?

The shape of the human red blood cell (RBC) is known to be a biconcave disc. The experiments in this paper identify some of the underlying determinates. RBC ghosts were made such that they were spheres in hypo-osmotic solutions and biconcave discs in iso-osmotic solutions.
