Fig. 1From: Patient-derived organoids (PDOs) as a novel in vitro model for neuroblastoma tumoursEstablishment of NB-PDOs. Bright-field images of PDOs morphological changes on day 7, day 14 and day 40. The isolated cells formed compact 3D structure (left panel, magnification 10x, scale bar 100 μm) and PDOs increase in size along with the cultivation time (middle and right panel, magnification 4x, scale bar 600 μm)Back to article page
