[HTML][HTML] Growth anisotropy of the extracellular matrix shapes a developing organ

S Harmansa, A Erlich, C Eloy, G Zurlo… - Nature …, 2023 - nature.com
Final organ size and shape result from volume expansion by growth and shape changes by
contractility. Complex morphologies can also arise from differences in growth rate between …

Protein binders and their applications in developmental biology

S Harmansa, M Affolter - Development, 2018 - journals.biologists.com
Developmental biology research would benefit greatly from tools that enable protein function
to be regulated, both systematically and in a precise spatial and temporal manner, in vivo. …

Dpp spreading is required for medial but not for lateral wing disc growth

S Harmansa, F Hamaratoglu, M Affolter, E Caussinus - Nature, 2015 - nature.com
Drosophila Decapentaplegic (Dpp) has served as a paradigm to study morphogen-dependent
growth control. However, the role of a Dpp gradient in tissue growth remains highly …

A nanobody-based toolset to investigate the role of protein localization and dispersal in Drosophila

S Harmansa, I Alborelli, D Bieli, E Caussinus, M Affolter - Elife, 2017 - elifesciences.org
10.7554/eLife.22549.001 The role of protein localization along the apical-basal axis of
polarized cells is difficult to investigate in vivo, partially due to lack of suitable tools. Here, we …

[PDF][PDF] Formation of polarized contractile interfaces by self-organized Toll-8/Cirl GPCR asymmetry

J Lavalou, Q Mao, S Harmansa, S Kerridge… - Developmental Cell, 2021 - cell.com
Interfaces between cells with distinct genetic identities elicit signals to organize local cell
behaviors driving tissue morphogenesis. The Drosophila embryonic axis extension requires …

[HTML][HTML] Forward and feedback control mechanisms of developmental tissue growth

S Harmansa, T Lecuit - Cells & Development, 2021 - Elsevier
The size and proportions of animals are tightly controlled during development. How this is
achieved remains poorly understood. The control of organ size entails coupling of cellular …

Wind fields in heterogeneous conifer canopies: parameterisation of momentum absorption using high-resolution 3D vegetation scans

R Queck, A Bienert, HG Maas, S Harmansa… - European Journal of …, 2012 - Springer
Applications of flow models to tall plant canopies are limited, amongst other factors, by the
lack of detailed information on vegetation structure. A method is presented to record 3D …

Myosin II is not required for Drosophila tracheal branch elongation and cell intercalation

A Ochoa-Espinosa, S Harmansa, E Caussinus… - …, 2017 - journals.biologists.com
The Drosophila tracheal system consists of an interconnected network of monolayered epithelial
tubes that ensures oxygen transport in the larval and adult body. During tracheal dorsal …

BMP morphogen gradients in flies

S Matsuda, S Harmansa, M Affolter - Cytokine & growth factor reviews, 2016 - Elsevier
Bone morphogenetic proteins (BMPs) act as morphogens to control patterning and growth
in a variety of developing tissues in different species. How BMP morphogen gradients are …

Growth anisotropy of the extracellular matrix drives mechanics in a developing organ

S Harmansa, A Erlich, C Eloy, G Zurlo, T Lecuit - Biorxiv, 2022 - biorxiv.org
The final size and shape of organs results from volume expansion by growth and shape
changes by contractility. Complex morphologies arise from differences in growth rate between …
