Overview
Jennifer Lippincott-Schwartz's Section on Organelle Biology continued to investigate new features of cellular processes by using novel fluorescence imaging approaches combined with quantitative analysis and mathematical modeling. Among the areas of investigation are (i) membrane partitioning and its role in protein sorting and transport in the Golgi apparatus, (ii) mitochondrial morphology and its regulation of cell cycle progression, (iii) control of primary cilia dynamics, (iv) intercellular transfer between stem and niche cells, (v) the origin of autophagosomes, (vi) live-cell photoactivation localization microscopy (PALM) for single-particle tracking, and (vii) cytoskeletal and endomembrane cross-talk in three-dimensional polarized cells and developing Drosophila syncytial blastoderm embryos.
