An exceptional progress
Pr McGuckin’s and Dr Forraz’s team (University of Newcastle) achieved to create a model of tiny liver from stem cells taken from umbilical cord blood. Umbilical cord blood is taken after the delivery without danger neither for the mother nor for the child. Scientists have placed these cord blood stem cells taken from newborn babies in a bioreactor designed by Nasa. The reproduced effects of weightlessness enabled cells to develop more rapidly and to transform with growth factors into 3D liver tissues. Thus, this team would be the first to made tissues of non-negligible size (few millimetres) in 3D from umbilical cord blood stem cells.
