> Directly after LAD ligation during MI surgery, hearts were injected twice with 15 μl of AAV9(CMV:GFP) or AAV9(CMV:HA-Hmga1) (1 × 1012 virus particles per mouse) in opposing regions bordering the area at risk of ischemic injury.
The paper doesn't say whether the viral vector (AAV9) used the murine or zebrafish Hmga1 sequence, but it is more likely that they used the murine.
