New preprint! Another piece from @gaparicio.bsky.social thesis, now exploring the role of PALS1 (aka Nok, or MPP5) in lamination and photoreceptor progenitors positioning in the developing zebrafish retina and retinal organoids: tinyurl.com/yya754tf
tinyurl.com
Reduction of PALS1/Nok disrupts retinal lamination through altered cell positioning while preserving photoreceptor self-organization capacity
The vertebrate neural retina is composed of several neuronal types that precisely organize into layers, with photoreceptors facing the outer surface and the projection neurons, retinal ganglion cells,...

Neurulation is mechanically expensive where shape and positional changes of the cell sheet take place. Using a vertex model, @fzolessi.bsky.social shows that it is the relative difference in surface tension between apical-basal vs lateral side that controls this process. doi.org/10.1016/j.cd...

I made this to demonstrate that for data visualization it's not only the color scheme, but the colors chosen for each channel, that matter. Here is the same image of rods and cones represented in RGB and simulated color blindness, showing how small changes can make a huge difference in what you see.
An image of a frog retina with photoreceptor labeling. The same image is shown 6 times in different colors. In the far left image, the small cones are difficult to detect in both the RGB and the color-blind simulated version. The middle image is the best representation of the data for fully sighted and color blind people, since the cones are easy to detect for both. The image on the right is better than the image on the far left to see the cones in RGB, but is still not color blind friendly.

Paper alert! Mechanical conditions preventing live cell extrusion during primary neurulation in amniotes. @sabr-bio.bsky.social article published as pre-proof in @cellsdev.bsky.social! doi.org/10.1016/j.cd...
Above: transverse sections of neurulating chick embryos stained for DNA (methyl green) and F-actin (TRITC-phalloidin), without and with the addition of the phorbol ester PMA. Below: computational simulations of pseudostratified epithelia, with different apicobasal/lateral tension ratios. Either PMA treatment in embryos, or lower ratios in simulations, cause epithelial instability evidenced by extensive cell extrusion.

Reaffirming the value of model organisms in training scientific minds - Nature Cell Biology
As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed. Here we argue that they have a lasting value, both in enabling discovery and in cultivating scientific thinking, by training researchers in systems reasoning, integrative thinking and independent inquiry.
