Felix Zhou's u-Segment3D is out:
www.nature.com/articles/s41...
It leverages 2D cell segmentations from orthoviews to generate a ‘consensus’ 3D segmentation.
It does a great job on segmenting densely packed samples, and we have used the algorithm in many applications.

We have observed a beautifully strange phenomenon of phase separation by human monocytes placed on soft matrix, which do it for survival.
We model it by incorporating the Cahn–Hilliard equation with a Turing mechanism of local activation/global inhibition
