GDF10 and Stroke: For instance, (1) the ages of the models were different in that they used adult animals whereas we used immature pups; (2) the pathophysiology of the models was different in that theirs was stroke with photothrombosis whereas ours was HI; and (3) because the mortality rate observed in our study was high, it is possible that only inherently resilient sur‘rs remained for evaluation (the mortality rate in the BMP-3b knock-down used in the report by Li and colleagues was not provided).
