Insight into pericytes in glioblastoma angiogenesis: In vivo tracking by two‐photon microscopy and proteomic profiling [PDF]

open access: yesAnimal Models and Experimental Medicine
Background Glioblastoma (GBM) is a highly aggressive brain tumor characterized by aberrant angiogenesis and an immunosuppressive microenvironment. Pericytes are aberrantly recruited but their spatiotemporal roles and molecular changes remain unclear ...

A new phase for two-photon microscopy [PDF]

open access: yesFrontiers in Neuroscience, 2009
Two-photon excitation has enabled remarkable advances in our understanding of the nervous system. Its three-dimensional resolution, superior depth penetration, and minimal phototoxicity for out-of-focus portions of the sample have made it the technique of choice for an impressive array of applications.
