The human macula is a highly specialized retinal region with pit‐like morphology and rich in cones. How Müller cells, the principal glial cell type in the retina, are adapted to this environment is still poorly understood. We compared proteomic data from cone‐ and rod‐rich retinae from human and mice and identified different expression profiles of cone‐ and rod‐associated Müller cells that converged...
Cell shape has long been thought to be the main cue for spindle positioning in mitotic cells, but new evidence suggests that, in the context of an epithelium, tricellular junctions encode positional information that helps orient mitotic spindles.
Accurate animal cell division requires precise coordination of changes in the structure of the microtubule-based spindle and the actin-based cell cortex. Here, we use a series of perturbation experiments to dissect the relative roles of actin, cortical mechanics, and cell shape in spindle formation. We find that, whereas the actin cortex is largely dispensable for rounding and timely mitotic progression...
Minimally Invasive Surgery (MIS) is widespread in medical procedures aiming to provide incision-less surgery. Conventional MIS provides limited tissue manipulation, because of the constrained directionality of force application and low number of Degrees of Freedom (DoFs). Robotic systems have been proposed to overcome the limitation of this approach, but still require the same number of incisions...
