In 2013, Doudna and her colleagues developed the CRISPR-Cas9 gene expression system that, when introduced into animal cells, makes site-specific changes to intact genomes. CRISPR-Cas9 is more precise, more efficient, and less expensive than other genome editing tools and, as a result, has facilitated a wide range of studies that were previously unachievable. https://www.leica-microsystems.com//science-lab/video-genome-engineering-with-crispr-cas9/ Fri, 09 Jun 2017 06:50:00 +0000 https://www.leica-microsystems.com/19530 CRISPR-Cas9 Video: Genome Editing with CRISPR-Cas9 Jennifer Doudna tells the story of how studying the way bacteria fight viral infection turned into a genomic engineering technology that has transformed molecular biology research.

Correlation of phenotype (what you can see) and genotype (genetic background) is highly desired but often biased by whole tissue approaches as no real solution is available to reliably separate the single cells of interest and surrounding tissue. Thus, results of DNA mutation analysis (sequencing), gene expression profiling (quantitative real-time PCR, qPCR, microarray, digital PCR), next generation sequencing (NGS) or mass spectrometry (MS) approaches can give mixed results as no pure starting material for the biomolecular methods of choice is available. https://www.leica-microsystems.com//science-lab/correlation-of-phenotype-and-genotype-microscopic-samples-and-their-biomolecular-backgrounds/ Thu, 20 Apr 2017 07:08:00 +0000 Dr. Falk Schlaudraff https://www.leica-microsystems.com/18921 Super-Resolution The Molecular Architecture of Hemidesmosomes as Revealed by Super-Resolution Microscopy Hemidesmosomes have been extensively studied by immunofluorescence microscopy, but due to its limited resolution, their precise organization remained poorly understood. We studied hemidesmosome organization in cultured keratinocytes by 2- and 3-color super-resolution microscopy. We observed that in the cell periphery, nascent hemidesmosomes are associated with individual keratin filaments and that β4 is distributed along rather than under keratin filaments. By applying innovative methods to quantify molecular distances, we demonstrate that the hemidesmosomal plaque protein plectin interacts simultaneously and asymmetrically with β4 and keratin. https://www.leica-microsystems.com//science-lab/the-molecular-architecture-of-hemidesmosomes-as-revealed-by-super-resolution-microscopy/ Fri, 10 Feb 2017 09:11:00 +0000 MSc Leila Nahidiazar https://www.leica-microsystems.com/18278 Super-Resolution Live-Cell Imaging Super-Resolution Optical Microscopy of Lipid Plasma Membrane Dynamics Plasma membrane dynamics are an important ruler of cellular activity, particularly through the interaction and diffusion dynamics of membrane-embedded proteins and lipids. FCS (fluorescence correlation spectroscopy) on an optical (confocal) microscope is a popular tool for investigating such dynamics. Unfortunately, its full applicability is constrained by the limited spatial resolution of a conventional optical microscope. The present chapter depicts the combination of optical super-resolution STED (stimulated emission depletion) microscopy with FCS, and why it is an important tool for investigating molecular membrane dynamics in living cells. Compared with conventional FCS, the STED-FCS approach demonstrates an improved possibility to distinguish free from anomalous molecular diffusion, and thus to give new insights into lipid–protein interactions and the traditional lipid ‘raft’ theory. https://www.leica-microsystems.com//science-lab/super-resolution-optical-microscopy-of-lipid-plasma-membrane-dynamics/ Fri, 23 Dec 2016 14:16:00 +0000 Prof. Christian Eggeling https://www.leica-microsystems.com/18885 Fluorescence Microscopy CRISPR-Cas9 Gene Editing with CRISPR/Cas9 - Breakthrough in Genome Engineering The CRISPR/Cas9 system is one of several different bacterial systems for defense against viral attacks. It consists of two main components. One is a small piece of RNA which binds to the viral target sequence via Watson-Crick base pairing. It serves as a marker for the foreign nucleic acid. The second component is the Cas9 protein. It binds to the marked sequence and cuts it due to its nuclease activity. Because the base pairing RNA can be synthesized easily and then used to determine a target region, researchers have utilized this system in the laboratory for genome editing. https://www.leica-microsystems.com//science-lab/gene-editing-with-crisprcas9-breakthrough-in-genome-engineering/ Thu, 17 Nov 2016 18:54:00 +0000 Dr. Christoph Greb https://www.leica-microsystems.com/18806 Super-Resolution Practical Guide for Excellent GSDIM Super-Resolution Images Do you know that most protists and bacteria lack in one feature that each of our body cell has? Our cells are touch and communicate with one another. They send and receive a variety of signals that coordinate their behavior to act together as a functional multicellular organism. Exploring the way of cellular communication and the ways how the cell surface interacts to organize tissues and body structures is of great interest. Kees Jalink and his team of scientists at the Netherlands Cancer Institute (NKI) in Amsterdam obtained new scientific insights into the molecular architecture of hemidesmosomes, cytoskeletal components, cell surface receptors and vesicular proteins with the help of Ground-State-Depletion (GSD)/ dSTORM microscopy. In this interview, Kees Jalink comments on their developments in imaging chambers, buffer conditions and image analysis to get the perfect super resolution image. https://www.leica-microsystems.com//science-lab/practical-guide-for-excellent-gsdim-super-resolution-images/ Wed, 26 Oct 2016 06:58:00 +0000 PhD Kees Jalink, PhD Tamara Straube, MSc Leila Nahidiazar, MSc Daniela Leyton Puig https://www.leica-microsystems.com/18919 Super-Resolution Initiation of Lamellipodia and Ruffles Involves Cooperation Between mDia1 and the Arp2/3 Complex Protrusion of lamellipodia and ruffles requires polymerization of branched actin filaments by the Arp2/3 complex. Although regulation of Arp2/3 complex activity has been extensively investigated, the mechanism of initiation of lamellipodia and ruffles remains poorly understood. Here, we show that mDia1 acts in concert with the Arp2/3 complex to promote initiation of lamellipodia and ruffles. https://www.leica-microsystems.com//science-lab/initiation-of-lamellipodia-and-ruffles-involves-cooperation-between-mdia1-and-the-arp23-complex/ Mon, 24 Oct 2016 11:47:00 +0000 https://www.leica-microsystems.com/18876 Super-Resolution Abstracts of the 6th European Super-Resolution User-Club Meeting The 6th European Super-Resolution User Club Meeting was held in collaboration with Dr. Timo Zimmermann, CRG, and Dr. Pablo Loza-Alvarez, ICFO, Barcelona.

During limb development, the apical ectodermal ridge (AER) is a key-signaling center responsible for early proximal–distal growth and patterning. In search for the mechanism, we examined the non-canonical Wnt signaling, considering that Dwnt-5 is a target of distalless in Drosophila and the knockout of Wnt5, Ryk, Ror2 and Vangl2 in the mouse causes severe limb malformations. https://www.leica-microsystems.com//science-lab/the-apical-ectodermal-ridge-of-the-mouse-model-of-ectrodactyly-dlx5dlx6-shows-altered-stratification-and-cell-polarity-which-are-restored-by-exogenous-wnt5a-ligand/ Wed, 07 Sep 2016 07:18:00 +0000 https://www.leica-microsystems.com/13942 Fluorescence Microscopy Quantitative Fluorescence Video Talk by Roger Tsien: Fluorescent Protein Indicators In this talk, Roger Tsien discusses how fluorescent proteins have been turned into indicators for a wide variety of biological molecules, including pH, ions, redox potential, and signaling molecules like phosphoinositides. The talk also covers reporters used to measure the activity of enzymes like kinases, phosphatases, and proteases. It covers both single proteins whose intensity or wavelength change, as well as reporters using Förster resonance energy transfer (FRET). https://www.leica-microsystems.com//science-lab/video-talk-by-roger-tsien-fluorescent-protein-indicators/ Tue, 16 Aug 2016 10:29:00 +0000 PhD Roger Y.

During this talk, given at Leica Microsystems in Wetzlar, Dr. Lennart Randau, MPI Marburg, presents this simple and fascinating system in detail. Furthermore, he introduces the adaption of the CRISPR-Cas system into a potent molecular biology tool, which is used heavily for genome editing. In addition to its influence on molecular biology, meanwhile the Cas9 nuclease also stimulates microscopy techniques e.g. to fluorescently label genomic loci in living cells. https://www.leica-microsystems.com//science-lab/video-talk-crispr-cas-from-a-bacterial-adaptive-immune-system-to-a-genome-engineering-tool/ Tue, 12 Jul 2016 04:13:00 +0000 Dr. Lennart Randau https://www.leica-microsystems.com/18271 Super-Resolution Quantitative Fluorescence Live-Cell Imaging STED-FLCS: An Advanced Tool to Reveal Spatiotemporal Heterogeneity of Molecular Membrane Dynamics Heterogeneous diffusion dynamics of molecules play an important role in many cellular signaling events, such as of lipids in plasma membrane bioactivity. However, these dynamics can often only be visualized by single-molecule and super-resolution optical microscopy techniques. Using fluorescence lifetime correlation spectroscopy (FLCS, an extension of fluorescence correlation spectroscopy, FCS) on a super-resolution stimulated emission depletion (STED) microscope, we here extend previous observations of nanoscale lipid dynamics in the plasma membrane of living mammalian cells. https://www.leica-microsystems.com//science-lab/sted-flcs-an-advanced-tool-to-reveal-spatiotemporal-heterogeneity-of-molecular-membrane-dynamics/ Mon, 11 Jul 2016 08:53:00 +0000 Ph.D. Giuseppe Vicidomini https://www.leica-microsystems.com/18431 Quantitative Fluorescence Live-Cell Imaging Individual Macromolecule Motion in a Crowded Living Cell There is solid evidence for analyzing fluorescence correlation and dual color fluorescence crosscorrelation spectroscopy data (FCS and dual color FCCS) in cellular applications by equations based on anomalous subdiffusion. Using equations based on normal diffusion causes artifacts of the fitted biological system response parameters and of the interpretations of the FCS and dual color FCCS data in the crowded environment of living cells. Equations based on normal diffusion are not valid in living cells. The original article embraces the status of the experimental situation and touches obstacles that still hinder the applications of single molecules in the cellular environment. https://www.leica-microsystems.com//science-lab/individual-macromolecule-motion-in-a-crowded-living-cell/ Mon, 27 Jun 2016 04:57:00 +0000 https://www.leica-microsystems.com/17977 Confocal Microscopy Live-Cell Imaging The Bimodally Expressed MicroRNA miR‐142 Gates Exit from Pluripotency A stem cell's decision to self‐renew or differentiate is thought to critically depend on signaling cues provided by its environment. It is unclear whether stem cells have the intrinsic capacity to control their responsiveness to environmental signals that can be fluctuating and noisy. Using a novel single‐cell microRNA activity reporter, we show that miR‐142 is bimodally expressed in embryonic stem cells, creating two states indistinguishable by pluripotency markers. https://www.leica-microsystems.com//science-lab/the-bimodally-expressed-microrna-mir-142-gates-exit-from-pluripotency/ Fri, 13 May 2016 13:47:00 +0000 https://www.leica-microsystems.com/16593 Super-Resolution Neuroscience Super-Resolution Microscopy of the Synaptic Active Zone At the presynaptic active zone (AZ) a variety of specialized proteins are assembled to complex architectures, which set the basis for speed, precision and plasticity of synaptic transmission. Recently, super-resolution microscopy (SRM) techniques have begun to enter the neurosciences. These approaches combine high spatial resolution with the molecular specificity of fluorescence microscopy. Here, we discuss how SRM techniques can be used to obtain information on the organization of AZ proteins. https://www.leica-microsystems.com//science-lab/super-resolution-microscopy-of-the-synaptic-active-zone/ Tue, 15 Dec 2015 10:15:00 +0000 Nadine Ehmann https://www.leica-microsystems.com/16814 Laser Microdissection Neuroscience Workflows & Protocols: Connecting Microscopy and Molecular Biology in Neuroscience The main topic during this course was how to apply laser microdissection in neuroscience.

Plants possess three types of DNA methyltransferases (MTases), namely Methyltransferase (MET), Chromomethylase (CMT) and Domains Rearranged Methyltransferase (DRM), which maintain methylation at CG, CHG and CHH sites. DNA MTases have not been studied in legumes so far. Here, we report the identification and analysis of putative DNA MTases in five legumes, including chickpea, soybean, pigeonpea, Medicago and Lotus. MTases in legumes could be classified in known MET, CMT, DRM and DNA nucleotide methyltransferases (DNMT2) subfamilies based on their domain organization. https://www.leica-microsystems.com//science-lab/genomic-survey-gene-expression-analysis-and-structural-modeling-suggest-diverse-roles-of-dna-methyltransferases-in-legumes/ Fri, 14 Mar 2014 11:29:00 +0000 https://www.leica-microsystems.com/12768 Neuroscience Confocal Microscopy Multiphoton Microscopy Map the Brain with CLARITY Imaging whole brains with CLARITY and multiphoton microscopy.
