Device and method for sorting biological entities

Francesco Mondada, Frank Bonnet, Norbert Crot, Marcin Antoni Sylwestrzak

A device for sorting biological entities is disclosed. The device comprises a channel to canalize the biological entities and a selector having slots to accommodate said entities. Means for detecting and analysing an optical parameter of the biological ent ...

Role of Cnot6l in maternal mRNA turnover

Jun Ma, Radek Jankele

Removal of poly(A) tail is an important mechanism controlling eukaryotic mRNA turnover. The major eukaryotic deadenylase complex CCR4-NOT contains two deadenylase components, CCR4 and CAF1, for which mammalian CCR4 is encoded by Cnot6 or Cnot6l paralogs. W ...

8-Channel Single Embryo Pipette For Accurate C-Elegans Bioassays

Martinus Gijs, Thomas Lehnert, Li Dong, Jingwei Zhang

The nematode Caenorhabditis elegans (C. elegans) is a powerful model organism for addressing fundamental biological questions related to human disease and aging. Accurate control of the number of worms is a primary step for quantitative biological or bioch ...

The double-edged toxins : how Spiroplasma Ribosome-Inactivating Proteins affect Drosophila melanogaster life history traits

Mario Gonzalo Garcia Arraez

Many insect species are associated with endosymbiotic bacteria which have the particularity of living within host tissues. Endosymbionts benefit from this stable and nutritious environment, while providing ecological advantages to their host, such as prote ...

In vivo pulse labeling of isochronic cohorts of cells in the central nervous system using FlashTag

Subashika Govindan

The tracing of neuronal cell lineages is critical to our understanding of cellular diversity in the CNS. This protocol describes a fluorescence birth-dating technique to label, track and isolate isochronic cohorts of newborn cells in the CNS in vivo in mou ...

Common and unique strategies of male killing evolved in two distinct Drosophila symbionts

Bruno Lemaitre, Toshiyuki Harumoto

Male killing is a selfish reproductive manipulation caused by symbiotic bacteria, where male offspring of infected hosts are selectively killed. The underlying mechanisms and the process of their evolution are of great interest not only in terms of fundame ...

An Integrated Microfluidic Device For C-Elegans Early Embryogenesis Studies And Drug Assays

Martinus Gijs, Pierre Gönczy, Thomas Lehnert, Matteo Cornaglia, Li Dong, Radek Jankele, Jingwei Zhang

The Caenorhabditis elegans embryo is a widely used model for the functional analysis of dynamic cellular processes, such as chromosome segregation, cytokinesis or lineage analysis. However, the conventional embryo preparation method that relies on manually ...

Ovary-specific depletion of the nuclear receptor Nr5a2 compromises expansion of the cumulus oophorus but not fertilization by intracytoplasmic sperm injection

Kristina Schoonjans

The orphan nuclear receptor, liver receptor homolog-1 (aka Nuclear receptor subfamily 5, Group A, Member 2 (Nr5a2)), is widely expressed in mammalian tissues, and its ovarian expression is restricted to granulosa cells of activated follicles. We employed t ...

DUX-family transcription factors regulate zygotic genome activation in placental mammals

Didier Trono, Andrea Coluccio, Evaristo Jose Planet Letschert, Julien Léonard Duc, Alberto De Iaco, Sonia Verp

In animal embryos, transcription is mostly silent for several cell divisions, until the release of the first major wave of embryonic transcripts through so-called zygotic genome activation (ZGA). Maternally provided ZGA-triggering factors have been identif ...

Segmentation of Developing Human Embryo in Time-lapse Microscopy

Mathieu Salzmann

Being able to efficiently segment a developing embryo from background clutter constitutes an important step in automated monitoring of human embryonic cells. State-of-the-art automatic segmentation methods remain ill-suited to handle the complex behavior a ...
