Summary

Reinhard Lipowsky presents a seminar on the modular route to synthetic cells, focusing on two main topics: division of synthetic cells and the synthetic endoplasmic reticulum. He begins by introducing the concept of bottom-up assembly of synthetic cells, contrasting with top-down minimal cells. He emphasizes the importance of understanding membrane elasticity, particularly spontaneous curvature, for controlling cell division. He presents experimental results using GFP binding to tune spontaneous curvature and induce fission in giant unilamellar vesicles (GUVs). He then discusses the morphology of the endoplasmic reticulum (ER), a network of membrane nanotubes, and the role of membrane proteins like atlastin in generating curvature and forming three-way junctions. He explains the physical principles behind the stability of three-way junctions and the fragmentation of ER tubes. The talk concludes with recent results from students, highlighting the ongoing research in the field.
