Top-bottom patterning of leaves is not specified by an asymmetry in the distribution of the plant hormone auxin, in contrast to a previous proposal.

Blastocyst complementation of rat embryos with donor mouse embryonic stem cells was used to simultaneously produce multiple, donor-derived hematopoietic and stromal cells in the interspecies bone marrow that exhibited normal gene expression signatures, cell surface markers, and functional characteristics.

A signal amplifier network that transmits mechanical pain is delineated through characterising an excitatory interneuron population in the spinal cord dorsal horn and defining the postsynaptic populations they regulate.

Pyramidal cells of the subiculum, a major output cell type of the hippocampus, can be deconstructed into distinct subtypes that exhibit a patchwork-like organization in space.

Functional neuroimaging in the human brain reveals the neurocognitive mechanisms that underpin the experience of mind-wandering during reading, explaining why comprehension is impaired.

Regional differences in activator and inhibitor signals alter hair cycle pace across mouse skin and produce unique fur renewal 'landscapes', with fastest renewal on the ventrum and slowest renewal on the ear pinnae.

Novel genetic fate-mapping strategies enabled re-analysis of cortical oligodendrocytes derived from dorsal pallium, LGE/CGE, and MGE/POA, challenging the canonical view of substantial LGE/CGE contributions and the elimination of MGE/POA-derived populations.

Secreted Vax1 homeodomain protein supports the development of optic chiasm by directly acting at the retinal ganglion cell axon.

Mathematical modeling of mutagenesis data for a suite of enhancers uncovers new relationships between the binding sites of transcription factors that help in genome-wide prediction of enhancers.

Dorsal raphe Pet1 neurons are molecularly heterogeneous, comprising as many as fourteen distinct subtypes that show biased cell body distributions across dorsal raphe subdomains.
