Human brain organoids help researchers study neurodevelopmental disorders that are difficult to examine directly in developing brain tissue. Giorgia Quadrato, USC, uses cortical organoids derived from human pluripotent stem cells to examine SYNGAP1, an autism risk gene associated in the transcript with intellectual disability, epilepsy, and global developmental delay. Quadrato describes how SYNGAP1 appears in progenitor cells as well as neurons, and how SYNGAP1 haploinsufficiency is linked to disrupted radial glia organization, altered cell division, and faster maturation of cortical projection neurons. She also discusses newer work focused on enteric neurons, gastrointestinal symptoms, and gut motility. By connecting brain development, autism genetics, and the enteric nervous system, this research points to models that may help test therapies and better understand symptoms that affect families.

Heart regeneration faces two connected challenges: replacing lost muscle and keeping transplanted cells safe and accepted by the body. Charles Murry, M.D., Ph.D., of USC explains why the adult heart heals major cardiomyocyte loss with scar tissue rather than new muscle, leading to progressive heart failure. Murry describes how stem cell derived cardiomyocytes can be manufactured at scale, transplanted into injured hearts, and tested for function in animal models. He also examines major barriers, including graft related arrhythmias, calcium handling stress, immune rejection, and the need for practical immunosuppression or immune edited cells. By connecting cell manufacturing, electrophysiology, immunology, and clinical trial planning, this research shows why heart regeneration is difficult and why careful translation matters for patients with severe heart injury.
