How Does Liquid-Liquid Phase Separation in Model Membranes Reflect Cell Membrane Heterogeneity?

It contains figures from Sych et al, Membranes, 2021. <br>First figure shows visualization of phase separation in synthetic and cell-derived membrane systems using phase selective probesSecond figure shows membrane order in liquid-ordered and liquid-disodered phases of synthetic and cell-derived membranes.Figures are provided in Inkscape svg format. Images are taken with confocal microscopy, and generalized polarization map was generated by using custom FiJi software (Sezgin et al, ChemPhysChem, 2015). <br><br>## Abstract of the paper<br>Although liquid–liquid phase separation of cytoplasmic or nuclear components in cells has<br>been a major focus in cell biology, it is only recently that the principle of phase separation has been<br>a long-standing concept and extensively studied in biomembranes. Membrane phase separation<br>has been reconstituted in simplified model systems, and its detailed physicochemical principles,<br>including essential phase diagrams, have been extensively explored. These model membrane systems<br>have proven very useful to study the heterogeneity in cellular membranes, however, concerns have<br>been raised about how reliably they can represent native membranes. In this review, we will discuss<br>how phase-separated membrane systems can mimic cellular membranes and where they fail to<br>reflect the native cell membrane heterogeneity. We also include a few humble suggestions on which<br>phase-separated systems should be used for certain applications, and which interpretations should<br>be avoided to prevent unreliable conclusions.<br>Researchers are welcome to use the data contained in the dataset for any projects.
