“…Organoids and other advanced 'engineered tissue' 3D models permit real-time, quantitative monitoring of genome organization (Lu et al, 2008;Hoppe et al, 2008;Wollman et al, 2020), self-organization of cellular processes (Lu et al, 2008;Hoppe et al, 2008;Wollman et al, 2020), metabolism, intracellular trafficking (Skruzny et al, 2020) and organelle-organelle interactions, as well as cancer cell migration, invasion and metastasis (Alexander et al, 2013;Steuwe et al, 2020), enabling an integrated understanding of the molecular biology of the cell in health and disease. Furthermore, metabolic FLIM and PLIM imaging are valuable tools in developmental biology and research into assisted reproductive technologies (Ma et al, 2019;Sosnik et al, 2016;Stringari et al, 2011Stringari et al, , 2012, and hold promise for improving tissue engineering, recreating stem cell niches and tumor microenvironments and developing advanced tissues-on-a-chip systems (Okkelman et al, 2020b;Ozturk et al, 2020;Floudas et al, 2020;Barron et al, 2020).…”
