Molecular and Proteomic Profiling of Human Cerebral Organoid‑Derived Small Extracellular Vesicles
Developmental Neurobiology, Volume 86, Issue 4, October 2026.ABSTRACT Organoids are self‐organized, in vitro 3D structures derived from progenitor or pluripotent stem cells. During culture, these tissues secrete small extracellular vesicles (sEVs)—functional bioactive molecules—into their microenvironment. Here, we differentiated iPSC‐derived cerebral organoids (COs) under three culture conditions (static ...
