Form follows function – Correlative volumeEM studies of organelles

One defining feature of eukaryotic cells is the presence of diverse set of membrane bound organelles, each hosting unique set of functions. The dynamic and complex organization of organelles poses a major challenge on understanding how organelle functioning – maintenance of the characteristic structure, distribution of its functions, and communication with other organelles – is orchestrated and how the organelle size, quantity and position within cell are determined and controlled.

In this talk, I will showcase our application of correlative volumeEM techniques, combined with custom-developed software, to quantitatively analyze the morphology of various organelles and their membrane contact sites. I will highlight our recent findings on the dynamics and structural organization of the ER in dendritic spines and the impact of Golgi organization on stem cell function in the small intestine.
