Localization and fate of Fgf10-expressing cells in the adult mouse brain implicate Fgf10 in control of neurogenesis.

We used Fgf10-lacZ reporter mice to investigate the distribution and fate of Fgf10-expressing cells in the developing and adult mouse brain. We find that the domain of Fgf10 expression expands post-natally and new niches emerge in the adult brain. Fgf10 is expressed in the adult cerebellum, thalamic, mid- and hindbrain nuclei and hippocampal CA fields, as previously reported in the rat brain. In addition though, we have discovered expression in: the hippocampal dentate gyrus; a discrete trail linking the ventral telencephalon with the olfactory bulbs; ventral ependyma of the third ventricle from where cells appear to disperse into the hypothalamus; and in the pituitary gland. Most Fgf10-expressing cells or their immediate descendants appear immature but a subset differentiates into neurons and glial cells. The manner in which Fgf10 is expressed in these active and quiescent neurogenic niches implicates it in control of neurogenesis and/or conservation of neurogenic potential

CMS physics technical design report: Addendum on high density QCD with heavy ions

This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies ,will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction - Quantum Chromodynamics (QCD) - in extreme conditions of temperature, density and parton momentum fraction (low-x). This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include "bulk" observables, (charged hadron multiplicity, low pT inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high pT hadrons which yield "tomographic" information of the hottest and densest phases of the reaction.0info:eu-repo/semantics/publishe
