The people behind the papers – Nathalia Azevedo Portilho, Rebecca Scarfò, Andrea Ditadi and Momoko Yoshimoto

Blood cells emerge in several waves through a number of different progenitors during embryonic development. A new paper in Development investigates whether the development of B1 lymphocytes, a type of B cell, is dependent on the differentiation of hematopoietic stem cells. To hear more about the story, we caught up with joint first authors Nathalia Azevedo Portilho and Rebecca Scarfò, and their respective supervisors Momoko Yoshimoto, Associate Professor at the University of Texas Health Science Center in Houston, USA, and Andrea Ditadi, Group Leader at the IRCCS Ospedale San Raffaele in Milan, Italy.
