Abstract:
Stem cell models for early mammalian development offer new experimental opportunities to access spatio-temporal details of the cell-cell interactions that govern cell differentiation and tissue patterning. This review summarizes recent studies that have used stem cell models to investigate the spatial range of developmental cell-cell communication systems. A key message from these works is that important biochemical signals for cell differentiation in these systems, such as Nodal and fibroblast growth factors (FGFs), often act over short distances of only a few cell diameters. The formation of long-range patterns at the tissue scale associated with these signals then results from signal relays and cell rearrangements. The modular view of differentiation and patterning emerging from research on stem cell models can offer a fresh perspective on the corresponding processes in the embryo.
