Generation of a Gal4-dependent gene recombination and illuminating mouse

Cell labeling technologies, including the Cre/loxP system, are powerful tools in developmental biology. Although the conventional Cre/loxP system has been extensively used to label the expression of specific genes, it is less frequently used for labeling p ...

Intestinal organoid cocultures with microbes

Devanjali Dutta

This protocol comprises various methods to coculture organoids (particularly human small intestinal and colon organoids) with microbes, including microinjection into the lumen and periphery of 3D organoids and exposure of organoids to microbes in a 2D laye ...

Optogenetic Dissection of the Basal Forebrain Neuromodulatory Control of Cortical Activation, Plasticity, and Cognition

Carl Petersen

The basal forebrain (BF) houses major ascending projections to the entire neocortex that have long been implicated in arousal, learning, and attention. The disruption of the BF has been linked with major neurological disorders, such as coma and Alzheimer's ...

AFM Based Single Cell Microinjection

Joanna Katarzyna Bitterli

The development of atomic force microscopy (AFM) has enabled a major breakthrough in the study of individual biological objects, such as nucleic acids, proteins and protein complexes. More recently the use of AFM to investigate eukaryotic cells has been ex ...

Role of non-specific DNA in reducing coding DNA requirement for transient gene expression with CHO and HEK-293E cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Divor Kiseljak, Sagar Shashidhar Manoli

Transient gene expression (TGE) is a rapid method for the production of recombinant proteins in mammalian cells. While the TGE volumetric productivity has improved significantly over the past decade, the amount of plasmid DNA (pDNA) needed for transfection ...

Assessing the cellular uptake pathway for poly-Lysine analogues using triplet lifetime imaging

Dimitri Nestor Alice Van De Ville, Theo Lasser, Harm-Anton Klok, Iwan Märki, Zuzana Kadlecova

Research on synthetic delivery vectors is of major interest for cell imaging and manipulation, as they allow an efficient transfer of nucleic acids, therapeutic proteins or small drugs into the cells. We have developed a library of L-lysine analogues that ...

Lentiviral Vector Mediated Transgenesis

Didier Trono, Isabelle Barde, Sonia Verp, Sandra Eloise Kjeldsen

The genetic manipulation of rodents through the generation of fully transgenic animals or via the modification of selective cells or organs is a procedure of paramount importance for biomedical research, either to address fundamental questions or to develo ...

Dll1- and Dll4-mediated Notch signaling is required for homeostasis of intestinal stem cells

Freddy Radtke, Ute Koch, Luca Pellegrinet, Shuang Chen

BACKGROUND & AIMS: Ablation of Notch signaling within the intestinal epithelium results in loss of proliferating crypt progenitors, due to their conversion into post-mitotic secretory cells. We aimed to confirm that Notch was active in stem cells (SC), inv ...

RhoV, a Potential Notch Target Gene in Murine Skin, Does not Play an Essential Role in Epidermis Development and Homeostasis

April Bezdek Pomey

The evolutionarily conserved Notch signaling cascade plays a pivotal role in the regulation of many fundamental processes such as stem cell maintenance, proliferation, and differentiation. Recently, we aimed to identify downstream target genes regulated by ...

Studies on lentiviral-mediated transgenesis

Marc-Olivier Sauvain

Transgenic animals are essential research tools, whether to address basic biological questions or to develop preclinical models of human diseases. Their generation through the injection of naked plasmid DNA into the male pronucleus of a fertilized oocyte h ...
