Here is a curated selection of preprints published recently. In this post, we focus specifically on preprints using microscopy tools in different fields such as cell biology, neuroscience, and development.
These two preprints were selected by Pablo J. Sáez who also participated in our Hot Reads post this month:
An anti-inflammatory activation sequence governs macrophage transcriptional dynamics during tissue injury. Nicolas Denans, Nhung T. T. Tran, Madeleine E. Swall, Daniel C. Diaz, Jillian Blanck, Tatjana Piotrowski
“Using beautiful in vivo imaging in zebrasifsh, the authors show that macrophage are sequentially activated to migrate towards the injury site and resolve inflammation. Elegant use of photoconversion to show that it is the same population of macrophages that perform this function.”
Mechanical intercellular communication via matrix-borne cell force transmission during vascular network formation. Christopher D. Davidson, Samuel J. DePalma, William Y. Wang, Jordan L. Kamen, Danica Kristen P. Jayco, Brendon M. Baker
“The authors show that mechanical intercellular communication between endothelial cells depends on calcium signaling and focal adhesion by using hydrogels. Cellular alignment of the fibers allows force transmission and cluster formation.”
A cellular and molecular atlas reveals the basis of chytrid development. Davis Laundon, Nathan Chrismas, Kimberley Bird, Seth Thomas, Thomas Mock, Michael Cunliffe
Quantitative live-imaging of Aquilegia floral meristems reveals distinct patterns of floral organ initiation and cell-level dynamics of floral meristem termination. Ya Min, Stephanie J. Conway, Elena M. Kramer
High definition DIC imaging uncovers transient stages of pathogen infection cycles on the surface of human adult stem cell-derived intestinal epithelium. Jorik M. van Rijn, Jens Eriksson, Jana Grüttner, Magnus Sundbom, Dominic-Luc Webb, Per M. Hellström, Staffan G. Svärd, Mikael E. Sellin
Optogenetic EB1 inactivation shortens metaphase spindles by disrupting cortical force-producing interactions with astral microtubules. Alessandro Dema, Jeffrey van Haren, Torsten Wittmann
