Figure 1. Profile of spheroid formation with the SUM1315 cell line in light microscopy.
Aggregates and spheroids were observed by light microscopy at Day 1, using ToupView® software. Spheroid formation was considered when cells were compacted in a unique and opaque to light aggregate. Magnification = 100X, scale bar = 200μm. (A) SUM1315 loose cell aggregates, (B) scattered spheroids, (C) single compact spheroid.
