    Hydrogel-in-Hydrogel Live Bioprinting for Guidance and Control of Organoids and Organotypic Cultures

    Modulation of hydrogel characteristics over time and according to culture evolution is often not possible. These limitations were overcome using a hydrogel-in-hydrogel live bioprinting approach that enabled the dynamic fabrication of instructive hydrogel elements within pre-existing hydrogel-based organ-like cultures.

    Cerebral Organoids Transplantation Repairs Infarcted Cortex and Restores Impaired Function after Stroke

    Scientists cultured human cerebral organoids derived from human pluripotent stem cells and transplanted them into the junction of the infarct core and the peri-infarct zone of NOD-SCID mice subjected to stroke.

    NIH Toughens Enforcement of Delayed Clinical Trials Reporting

    The US National Institutes of Health (NIH) delivered a stern warning to two in-house clinical researchers who had broken an important rule. They had failed to submit the results of two clinical trials they had overseen to ClinicalTrials.gov, a database meant to inform the public about human studies and their results.
