A biphasic growth model for cell pole elongation in mycobacteria

Georg Fantner, John McKinney, Haig Alexander Eskandarian, Mélanie Thérèse Marie Hannebelle, Chiara Toniolo, Joëlle Xiao Yuan Ven, Gaëlle Madeleine Vuaridel

Mycobacteria grow by inserting new cell wall material in discrete zones at the cell poles. This pattern implies that polar growth zones must be assembled de novo at each division, but the mechanisms that control the initiation of new pole growth are unknow ...

High-speed multiplane structured illumination microscopy of living cells using an image-splitting prism

Theo Lasser, Aleksandra Radenovic, Vytautas Navikas, Tomas Lukes, Adrien Charles-François Raymond Descloux

Super-resolution structured illumination microscopy (SR-SIM) can be conducted at video-rate acquisition speeds when combined with high-speed spatial light modulators and sCMOS cameras, rendering it particularly suitable for live-cell imaging. If, however, ...

Centriole foci persist in starfish oocytes despite Polo-like kinase 1 inactivation or loss of microtubule nucleation activity

Pierre Gönczy, Nils Kalbfuss, Marie Juliette Ségolène Pierron

Centrioles must be eliminated or inactivated from the oocyte to ensure that only the two functional centrioles contributed by the sperm are present in the zygote. Such removal can occur during oogenesis, as in Drosophila, where departure of Polo kinase fro ...

Mechano-modulatory synthetic niches for liver organoid derivation

Kristina Schoonjans, Matthias Lütolf, Giovanni Sorrentino, Saba Rezakhani, Ece Yildiz

The recent demonstration that primary cells from the liver can be expanded in vitro as organoids holds enormous promise for regenerative medicine and disease modelling. The use of three-dimensional (3D) cultures based on ill-defined and potentially immunog ...

Traceable Impedance-Based Dispensing and Cloning of Living Single Cells

Philippe Renaud, Yann Barrandon, Ariane Rochat, David Vincent Bonzon, Stéphanie Claudinot, Georges Muller

Single-cell cloning is essential in stem cell biology, cancer research, and biotechnology. Regulatory agencies now require an indisputable proof of clonality that current technologies do not readily provide. Here, we report a one-step cloning method using ...

Topology of Pretreated Wood Fibers Using Dynamic Nuclear Polarization

David Lyndon Emsley, Jeremy Luterbacher, Arthur César Pinon, Pierrick Berruyer, Jasmine Viger-Gravel, Wu Lan, Michel Bardet

In the continuously developing field of lignocellulosic biomass, high-yield lignin depolymerization processes are sought to optimize its productivity and profitability. Recently, formaldehyde stabilization during lignin extraction and biomass pretreatment ...

Overlapping and essential roles for molecular and mechanical mechanisms in mycobacterial cell division

Georg Fantner, John McKinney, Adrian Pascal Nievergelt, Pascal Damian Odermatt, Haig Alexander Eskandarian, Mélanie Thérèse Marie Hannebelle

Mechanisms to control cell division are essential for cell proliferation and survival. Bacterial cell growth and division require the coordinated activity of peptidoglycan synthases and hydrolytic enzymes to maintain mechanical integrity of the cell wall. ...

Cell-Imprint Surface Modification by Contact Photolithography-Based Approaches: Direct-Cell Photolithography and Optical Soft Lithography Using PDMS Cell Imprints

Philippe Renaud, Harald Van Lintel, Shahin Bonakdar, Hanie Kavand

New cell-imprint surface modification techniques based on direct-cell photolithography and optical soft lithography using poly(dimethylsiloxane) (PDMS) cell imprints are presented for enhanced cell-based studies. The core concept of engineering materials f ...
