Journal ArticleDOI
A novel multistep mechanism for initial lymphangiogenesis in mouse embryos based on ultramicroscopy.
René Hägerling,Cathrin Pollmann,Martin Andreas,Christian Schmidt,Harri Nurmi,Ralf H. Adams,Kari Alitalo,Volker Andresen,Stefan Schulte-Merker,Friedemann Kiefer +9 more
TL;DR: A significantly more detailed view and novel model of early lymphatic development is presented and vascular endothelial growth factor C (VEGF‐C) and the matrix component CCBE1 indispensable for LEC budding and migration are found.
Journal ArticleDOI
The Power of Single and Multibeam Two-Photon Microscopy for High-Resolution and High-Speed Deep Tissue and Intravital Imaging
TL;DR: A multifocal scanhead splitting a laser beam into a line of 64 foci is utilized, allowing sample illumination in real time at full laser power, and it is found that the point-spread function of both devices strongly depends on tissue constitution and penetration depth.
Journal ArticleDOI
Parallelized TCSPC for dynamic intravital fluorescence lifetime imaging: quantifying neuronal dysfunction in neuroinflammation.
Jan Leo Rinnenthal,Christian Börnchen,Helena Radbruch,Helena Radbruch,Volker Andresen,Agata Mossakowski,Volker Siffrin,Volker Siffrin,Thomas Seelemann,Heinrich Spiecker,Ingrid Moll,Josephine Herz,Josephine Herz,Anja E. Hauser,Frauke Zipp,Frauke Zipp,Martin J. Behne,Raluca Niesner,Raluca Niesner +18 more
TL;DR: The new technology allows us to perform time-lapse 3D intravital FLIM (4D FLIM) in the brain stem of CerTN L15 mice affected by experimental autoimmune encephalomyelitis and, thereby, to truly quantify neuronal dysfunction in neuroinflammation.
Journal ArticleDOI
Intravital two-photon microscopy of lymphatic vessel development and function using a transgenic Prox1 promoter-directed mOrange2 reporter mouse.
TL;DR: The Prox1 (prospero homeobox protein 1) promoter-driven expression of the fluorescent protein mOrange2 allows the specific intravital visualization of lymph vessel growth and behaviour during mouse fetal development and in adult mice.
Journal ArticleDOI
Intravital two-photon microscopy: focus on speed and time resolved imaging modalities.
TL;DR: Current available two‐photon microscopy techniques are described with a focus on novel approaches that allow very high image acquisition rates compared with state‐of‐the‐art systems, and the analysis of endogenous fluorophores such as NAD(P)H as a way to analyze the redox status in cells with subcellular resolution.
