[HTML][HTML] Loss of FGF-dependent mesoderm identity and rise of endogenous retinoid signalling determine cessation of body axis elongation

I Olivera-Martinez, H Harada, PA Halley… - PLoS biology, 2012 - journals.plos.org

regulation; however, little is known about how such organisation alters during embryonic …

FGF-dependent Notch signaling maintains the spinal cord stem zone

J Akai, PA Halley, KG Storey - Genes & development, 2005 - genesdev.cshlp.org
Generation of the spinal cord relies on proliferation of undifferentiated cells located in a caudal
stem zone. Although fibroblast growth factor (FGF) signaling is required to maintain this …

Wnt regulates amino acid transporter Slc7a5 and so constrains the integrated stress response in mouse embryos

N Poncet, PA Halley, C Lipina, M Gierliński, A Dady… - EMBO …, 2020 - embopress.org
Amino acids are essential for cellular metabolism, and it is important to understand how nutrient
supply is coordinated with changing energy requirements during embryogenesis. Here, …

Human spinal cord in vitro differentiation pace is initially maintained in heterologous embryonic environments

A Dady, L Davidson, PA Halley, KG Storey - Elife, 2022 - elifesciences.org
