Shaping up : Two papers in 'Development' from the Martinez Arias Group

last modified Nov 06, 2014 09:07 AM
Members of the Martinez Arias Lab in the Department of Genetics have been able to reconstruct the early stage of mammalian development using embryonic stem cells, showing that a critical mass of cells is needed for the cells to being self-organising into the correct structure for an embryo to form.

The research is published in two papers in 'Development':

Susanne C Van den Brink, Peter Baillie-Johnson, Tina Balayo, Anna-Katerina Hadjantonakis, Sonja Nowotschin, David A. Turner and Alfonso Martinez Arias : Symmetry breaking, germ layer specification and axial organisation in aggregates of mouse ES cells. Development; 4 Nov 2104.

David A. Turner, Penelope C. Hayward, Peter Baillie-Johnson, Pau Rue, Rebecca Broome, Fernando Faunes and Alfonso Martinez Arias :  Wnt/β-catenin and FGF signalling direct the specification and maintenance of a neuromesodermal axial progenitor in ensembles of mouse ES cells. Development; 4 Nov 2104.

Image : Mouse Embryonic Stem cells bearing a reporter for Wmt signalling. The left picture shows a group of ES cells displaying Wnt signalling (red)  in adherent culture, the middle one is the same cells in an elongating ‘organoid” which we call a ‘gastruloid” -notice the localized expression of the reporter-; finally the picture on the right is an embryo bearing the Wnt reporter at a stage we reckon mimics that of the aggregates in the middle.
