Abstract

Endothelial cells (ECs) grow as single layers on the bottom surface of cell culture flasks under normal (1g) culture conditions. In numerous experiments using simulated microgravity we noticed that the ECs formed three-dimensional, tube-like cell aggregates resembling the intima of small, rudimentary blood vessels. The SPHEROIDS project has now shown that similar processes occur in space. For the first time, we were able to observe scaffold-free growth of human ECs into multicellular spheroids and tubular structures during an experiment in real microgravity. With further investigation of the space samples we hope to understand endothelial 3D growth and to improve the in vitro engineering of biocompatible vessels which could be used in surgery.
