Guichard L, Lagadec R, Michel L, Mayeur H, Fuentes M, Pain J, et al.
Front Cell Dev Biol . 2025 Feb; 13:1528797. PMID: 39981098
By their phylogenetic position and their marked epithalamic asymmetries, lampreys are relevant models for understanding the formation and evolution of this trait across vertebrates. In this study, we use a...

Lanoizelet M, Michel L, Lagadec R, Mayeur H, Guichard L, Logeux V, et al.
Nat Commun . 2024 Nov; 15(1):10194. PMID: 39587074
The mode of evolution of left-right asymmetries in the vertebrate habenulae remains largely unknown. Using a transcriptomic approach, we show that in a cartilaginous fish, the catshark Scyliorhinus canicula, habenulae...

Michel L, Palma K, Cerda M, Lagadec R, Mayeur H, Fuentes M, et al.
Front Cell Dev Biol . 2022 Nov; 10:1015074. PMID: 36407110
Habenulae asymmetries are widespread across vertebrates and analyses in zebrafish, the reference model organism for this process, have provided insight into their molecular nature, their mechanisms of formation and their...

Schmidt P, Leman E, Lagadec R, Schubert M, Mazan S, Reshef R
Cells . 2022 Apr; 11(8). PMID: 35455988
The anterior-posterior (AP) axis in chordates is regulated by a conserved set of genes and signaling pathways, including genes and retinoic acid (RA), which play well-characterized roles in the organization...

Mayeur H, Lanoizelet M, Quillien A, Menuet A, Michel L, Martin K, et al.
Front Cell Dev Biol . 2021 Nov; 9:744982. PMID: 34746140
We report the adaptation of RNA tomography, a technique allowing spatially resolved, genome-wide expression profiling, to a species occupying a key phylogenetic position in gnathostomes, the catshark . We focused...

Lagadec R, Lanoizelet M, Sanchez-Farias N, Herard F, Menuet A, Mayeur H, et al.
Sci Rep . 2018 Mar; 8(1):4616. PMID: 29545638
Analysis of the establishment of epithalamic asymmetry in two non-conventional model organisms, a cartilaginous fish and a lamprey, has suggested that an essential role of Nodal signalling, likely to be...

Steventon B, Duarte F, Lagadec R, Mazan S, Nicolas J, Hirsinger E
Development . 2016 Mar; 143(10):1732-41. PMID: 26989170
Posterior body elongation is a widespread mechanism propelling the generation of the metazoan body plan. The posterior growth model predicts that a posterior growth zone generates sufficient tissue volume to...

Santos-Duran G, Menuet A, Lagadec R, Mayeur H, Ferreiro-Galve S, Mazan S, et al.
Front Neuroanat . 2015 Apr; 9:37. PMID: 25904850
The hypothalamus has been a central topic in neuroanatomy because of its important physiological functions, but its mature organization remains elusive. Deciphering its embryonic and adult organization is crucial in...

Lagadec R, Laguerre L, Menuet A, Amara A, Rocancourt C, Pericard P, et al.
Nat Commun . 2015 Mar; 6:6686. PMID: 25819227
Left-right asymmetries in the epithalamic region of the brain are widespread across vertebrates, but their magnitude and laterality varies among species. Whether these differences reflect independent origins of forebrain asymmetries...

Godard B, Coolen M, Le Panse S, Gombault A, Ferreiro-Galve S, Laguerre L, et al.
Biol Open . 2014 Nov; 3(11):1098-107. PMID: 25361580
In order to gain insight into the impact of yolk increase on endoderm development, we have analyzed the mechanisms of endoderm formation in the catshark S. canicula, a species exhibiting...
