Growth of low grade CSA spheroids. Cell line SW1353 and three patient-derived primary cells CS15, S26, S564 were seeded into ULA plates at initial density of 20,000 cells per well. The formed spheroids were representatively imaged at time point of day 1, day 3, day 7 and day 10 respectively. For each sample, n = 10, scale bar = 100 μm. Red arrows indicates the transparent matrix secreted by S564 spheroid.
