Evolutionarily recent transcription factors partake in human cell cycle regulation

Didier Trono, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Charlène Mireille Raymonde Raclot, Alex Russell Lederer, Cyril David Son-Tuyên Pulver, Olga Marie Louise Rosspopoff, Romain Forey, Alexandre Coudray

The cell cycle is a fundamental process in eukaryotic biology and is accordingly controlled by a highly conserved core signaling cascade. However, whether recently evolved proteins also influence this process is unclear. Here, we systematically map the inf ...

Clinically compliant cryopreservation of differentiated retinal pigment epithelial cells

Gioele La Manno, Alex Russell Lederer, Cheng Zhao

Background aims: Age-related macular degeneration (AMD) is the most common cause of blindness in elderly patients within developed countries, affecting more than 190 million worldwide. In AMD, the retinal pigment epithelial (RPE) cell layer progressively d ...

Statistical inference with a manifold-constrained RNA velocity model uncovers cell cycle speed modulations

Felix Naef, Gioele La Manno, Alex Russell Lederer, Irina Khven, Antonio Herrera Camacho, Albert Dominguez Mantes, Colas Noé Droin, Lorenzo Talamanca

Across biological systems, cells undergo coordinated changes in gene expression, resulting in transcriptome dynamics that unfold within a low-dimensional manifold. While low-dimensional dynamics can be extracted using RNA velocity, these algorithms can be ...

Deciphering the nature of cell state transitions in single cells using quantitative modeling of temporal dynamics

Alex Russell Lederer

Cells are the smallest operational units of living systems. Through synthesis of various biomolecules and exchange of signals with the environment, cells tightly regulate their composition to realize a specific functional state. The transformation of a cel ...

Molecular profiling of stem cell-derived retinal pigment epithelial cell differentiation established for clinical translation

Gioele La Manno, Alex Russell Lederer, Irina Khven

Human embryonic stem cell-derived retinal pigment epithelial cells (hESC-RPE) are a promising cell source to treat age-related macular degeneration (AMD). Despite several ongoing clinical studies, a detailed mapping of transient cellular states during in v ...

Sphingolipids control dermal fibroblast heterogeneity

Giovanni D'Angelo, Gioele La Manno, Olivier Burri, Romain Guiet, Sylvia Ho, Alex Russell Lederer, Laura Capolupo, Irina Khven, Galina Glousker

Human cells produce thousands of lipids that change during cell differentiation and can vary across individual cells of the same type. However, we are only starting to characterize the function of these cell-to-cell differences in lipid composition. Here, ...

Molecular architecture of the developing mouse brain

Gioele La Manno, Alex Russell Lederer, Irina Khven

The mammalian brain develops through a complex interplay of spatial cues generated by diffusible morphogens, cell-cell interactions and intrinsic genetic programs that result in probably more than a thousand distinct cell types. A complete understanding of ...

NATURE PORTFOLIO2021

The emergence and promise of single-cell temporal-omics approaches

Gioele La Manno, Alex Russell Lederer

Single-cell transcriptomics enables the measurement of gene expression in complex biological systems at the resolution of individual cells. Multivariate analysis of single-cell data helps describe the variation in expression accompanying cellular processes ...
