MPO and intracranial hemorrhage: Larvae from heterozygous adult bbh Tg[mpo:GFP;mpeg1:mcherry] (referred to as mpo:mpeg) in-crosses were collected and light microscopy used to identify brain hemorrhages (ICH+) in homozygotes, which were separated from non-hemorrhaged (ICH–) heterozygous and wild-type siblings at ~52 hpf.
