In Situ and Time-Resolved Transmission Electron Microscopy of Nanoscale Processes

Observing the fast dynamics of nanoscale systems is crucial in order to understand and ultimately control their behavior. Characterizing these dynamic processes requires techniques with atomic spatial resolution and a temporal resolution that matches the t ...

Mechanics of the cellular microenvironment as probed by cells in vivo during zebrafish presomitic mesoderm differentiation

Sangwoo Kim

Tissue morphogenesis, homoeostasis and repair require cells to constantly monitor their three-dimensional microenvironment and adapt their behaviours in response to local biochemical and mechanical cues. Yet the mechanical parameters of the cellular microe ...

EASI-FISH for thick tissue defines lateral hypothalamus spatio-molecular organization

Martin Weigert, Hui Yang

Determining the spatial organization and morphological characteristics of molecularly defined cell types is a major bottleneck for characterizing the architecture underpinning brain function. We developed Expansion Assisted Iterative Fluorescence In Situ H ...

Fryns type mesomelic dysplasia of the upper limbs caused by inverted duplications of the HOXD gene cluster

Denis Duboule

The HoxD cluster is critical for vertebrate limb development. Enhancers located in both the telomeric and centromeric gene deserts flanking the cluster regulate the transcription of HoxD genes. In rare patients, duplications, balanced translocations or inv ...

HISTOBREAST, a collection of brightfield microscopy images of Haematoxylin and Eosin stained breast tissue

Tiberiu Totu

Modern histopathology workflows rely on the digitization of histology slides. The quality of the resulting digital representations, in the form of histology slide image mosaics, depends on various specific acquisition conditions and on the image processing ...

Detection of mRNA by Whole Mount in situ Hybridization and DNA Extraction for Genotyping of Zebrafish Embryos

Andrew Charles Oates, Rachna Narayanan

In situ hybridization is used to visualize the spatial distribution of gene transcripts in tissues and in embryos, providing important information about disease and development. Current methods involve the use of complementary riboprobes incorporating non- ...

High-content, cell-by-cell assessment of HER2 overexpression and amplification: a tool for intratumoral heterogeneity detection in breast cancer

Martinus Gijs, Daniel Migliozzi, Huu Tuan Nguyen

Immunohistochemistry and fluorescence in situ hybridization are the two standard methods for human epidermal growth factor receptor 2 (HER2) assessment. However, they have severe limitations to assess quantitatively intratumoral heterogeneity (ITH) when mu ...

Improvement of breast cancer diagnosis through microfluidics

Huu Tuan Nguyen

In breast cancer, 15-20% of cases are reported with overexpression of human epidermal growth factor receptor 2 (HER2) that causes rapid cancer progression and poor prognosis. Fortunately, HER2-targeted therapy using specific antibodies such as Trastuzumab ...

Microfluidics-assisted fluorescence in situ hybridization for advantageous human epidermal growth factor receptor 2 assessment in breast cancer

Martinus Gijs, Raphaël Etienne Jean Trouillon, Maryse Fiche, Huu Tuan Nguyen, Seiya Matsuoka

Fluorescence in situ hybridization (FISH) is one of the recommended techniques for human epidermal growth factor receptor 2 (HER2) status assessment on cancer tissues. Here we develop microfluidics-assisted FISH (MA-FISH), in which hybridization of the FIS ...

Microfluidic-assisted chromogenic in situ hybridization (MA-CISH) for fast and accurate breast cancer diagnosis

Martinus Gijs, Raphaël Etienne Jean Trouillon, Huu Tuan Nguyen, Léa Suzanne Bernier

Chromogenic in situ hybridization (CISH) is a common technique that is used for human epidermal growth factor receptor 2 (HER2) assessment in breast cancer diagnosis. CISH is based on the enzymatic amplification of DNA markers, generating a colorimetric im ...
