Specification of cell identity during development depends on exposure of cells to sequences of extrinsic cues delivered at precise times and concentrations. Identification of combinations of patterning molecules that control cell fate is essential for the effective use of human pluripotent stem cells (hPSCs) for basic and translational studies. Here we(More)
We report that Emx2 homeogene is expressed at the mRNA and protein levels in the adult mouse olfactory neuroepithelium. As expected for a transcription factor, Emx2 is present in the nucleus of immature and mature olfactory sensory neurons. However, the protein is also detected in the axonal compartment of these neurons, both in the olfactory mucosa axon(More)
Engrailed1 (En1) is a homeoprotein transcription factor expressed throughout adulthood in several midbrain cells, including the dopaminergic neurons of the substantia nigra. Here we report the presence of Engrailed protein and En1 mRNA in proximal dendrites of these neurons and of En1 mRNA in ventral midbrain synaptoneurosomes. We show that the 3'(More)
The main organization and gross morphology of the mammalian olfactory primary pathway, from the olfactory epithelium to the olfactory bulb, has been initially characterized using classical anatomical and ultrastructural approaches. During the last fifteen years, essentially thanks to the cloning of the odorant receptor genes, and to the characterization of(More)
