Positional data is supplemented with a range of information including the relative location of the closest ureteric tip and a correction for drift due to bulk movement and tip growth. …”

We found that progenitors are dependent on p57(KIP2)-mediated slowing of replication forks for self-renewal, a novel function for cyclin-dependent kinase inhibitors. …”

36296por Horn, John P.“…A recent developmental study of gene expression by Espinosa-Medina, Brunet and colleagues sparked controversy by asserting a revised nomenclature for divisions of the autonomic motor system. Should we re-classify the sacral autonomic outflow as sympathetic, as now suggested, or does it rightly belong to the parasympathetic system, as defined by Langley nearly 100 years ago? …”
