No, it’s not The Grinch, but organoids are a great Christmas in July gift for the preclinical researchers in your life. Drugmakers spend tons just to get their drugs to Phase I research but could lose big if too many side effects occur in these first rounds of human trials. For instance, only 6.6% of Phase I cardiovascular INDs make it to Phase II. Wouldn’t it be nice if we could test a drug’s effects on say, a model of the human heart? Some biotech companies have recently developed the means to create 3D assays known as organoids—artificially-grown cell structures that can actually mimic organ functions instead of just the compositions of those organs (i.e. older 3D assays.) Watch out for more companies contracting their services to cut down on investment and—more importantly—patient risk.
