Characterisation of directed maturation in human cardiac organoids

Cardiac maturation is an important developmental phase where there are profound biological and functional changes after birth in mammals. Herein, we use our profiling of human heart maturation in vivo to identify key drivers of maturation in our human cardiac organoid (hCO) model. After screening of various metabolism modulating factors, we established a directed maturation (DM) protocol to induce mature cardiac expression and compared the proteomic changes to our original serum free (SF) protocol. In this dataset, we compared 4 replicates of DM to 4 replicates of SF derived cardiac organoids using global DIA-MS/MS.
