First person – Antonio Barral and Isabel Rollan

First Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping early-career researchers promote themselves alongside their papers. Antonio Barral and Isabel Rollan are co-first authors on ‘Nanog regulates Pou3f1 expression at the exit from pluripotency during gastrulation’, published in BiO. Antonio is a PhD student in the lab of Miguel Manzanares at Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), Spain, investigating embryonic development, pluripotency and reprogramming. Isabel is a technical officer at the European Molecular Biology Laboratory (EMBL), Germany, in the lab of Alexander Aulehla, investigating gene editing, embryonic development and gene regulation.
