Single-cell epigenomic reconstruction of developmental trajectories from pluripotency in human neural organoid systems

Fides Zenk

Cell fate progression of pluripotent progenitors is strictly regulated, resulting in high human cell diversity. Epigenetic modifications also orchestrate cell fate restriction. Unveiling the epigenetic mechanisms underlying human cell diversity has been di ...

ISSCR standards for the use of human stem cells in basic research

Matthias Lütolf

The laboratory culture of human stem cells seeks to capture a cellular state as an in vitro surrogate of a biological system. For the results and outputs from this research to be accurate, meaning-ful, and durable, standards that ensure reproducibility and ...

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

Gioele La Manno, Irina Khven, Alex Russell Lederer

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 ...

An extended regulatory landscape drives Tbx18 activity in a variety of prostate-associated cell lineages

Christopher Chase Bolt

The evolutionarily conserved transcription factor, Tbx18, is expressed in a dynamic pattern throughout embryonic and early postnatal life and plays crucial roles in the development of multiple organ systems. Previous studies have indicated that this dynami ...

Efficient transdifferentiation of human dermal fibroblasts into skeletal muscle

Noaf Salah Ali Alwahab

Skeletal muscle holds significant regenerative potential but is incapable of restoring tissue loss caused by severe injury, congenital defects or tumour ablation. Consequently, skeletal muscle models are being developed to study human pathophysiology and r ...

Pharmacological induction of a progenitor state for the efficient expansion of primary human hepatocytes

Didier Trono, Matthias Lütolf, Evaristo Jose Planet Letschert, Marc Samuel Friedli, Nathalie Brandenberg, Marco Cassano, Carmen Maria Unzu Ezquerro

The liver is an organ with strong regenerative capacity, yet primary hepatocytes have a low amplification potential in vitro, a major limitation for the cell-based therapy of liver disorders and for ex vivo biological screens. Induced pluripotent stem cell ...

Machine Learning Identifies Stemness Features Associated with Oncogenic Dedifferentiation

Jia Liu, Jian Wang, Jun Li, Min Wang

Cancer progression involves the gradual loss of a differentiated phenotype and acquisition of progenitor and stem-cell-like features. Here, we provide novel stemness indices for assessing the degree of oncogenic dedifferentiation. We used an innovative one ...

Beneficial effects of Human Mesenchymal Stromal Cells on Porcine Hepatocyte Viability and Albumin Secretion

Sandrine Gerber, Solène Marcelle Françoise Marie Passemard, François Rémi Pierre Noverraz, Luca Szabó

Porcine hepatocytes transplanted during acute liver failure might support metabolic functions until the diseased liver recovers its function. Here, we isolated high numbers of viable pig hepatocytes and evaluated hepatocyte functionality after encapsulatio ...

Reprogramming tumor blood vessels for enhancing immunotherapy

Michele De Palma

Angiogenic blood vessels contribute to generating an immunosuppressive tumor microenvironment, in part by limiting the extravasation of T cells. Functional reprogramming of angiogenic blood vessels, for example through angiopoietin-2 blockade, may improve ...

Defined three-dimensional microenvironments boost induction of pluripotency

Matthias Lütolf, Alessandra Piersigilli, Adrian Ranga, Yoji Tabata, Yuya Okawa, Massimiliano Caiazzo

Since the discovery of induced pluripotent stem cells (iPSCs), numerous approaches have been explored to improve the original protocol, which is based on a two-dimensional (2D) cell-culture system. Surprisingly, nothing is known about the effect of a more ...

Non-integrating episomal plasmid-based reprogramming of human amniotic fluid stem cells into induced pluripotent stem cells in chemically defined conditions

Amniotic fluid stem cells (AFSC) represent an attractive potential cell source for fetal and pediatric cell-based therapies. However, upgrading them to pluripotency confers refractoriness toward senescence, higher proliferation rate and unlimited different ...

Molecular Criteria for Defining the Naive Human Pluripotent State

Didier Trono, Evaristo Jose Planet Letschert, Julien Léonard Duc, Marc Samuel Friedli, Michaël Imbeault, Julien Paul André Pontis, Alexandra Iouranova

Recent studies have aimed to convert cultured human pluripotent cells to a naive state, but it remains unclear to what extent the resulting cells recapitulate in vivo naive pluripotency. Here we propose a set of molecular criteria for evaluating the naive ...

Cardiac Niche Influences the Direct Reprogramming of Canine Fibroblasts into Cardiomyocyte-Like Cells

Marco Cassano

The Duchenne and Becker muscular dystrophies are caused by mutation of dystrophin gene and primarily affect skeletal and cardiac muscles. Cardiac involvement in dystrophic GRMD dogs has been demonstrated by electrocardiographic studies with the onset of a ...

Cell Cycle-Dependent Differentiation Dynamics Balances Growth and Endocrine Differentiation in the Pancreas

Anne Grapin-Botton, Yung Hae Kim

Organogenesis relies on the spatiotemporal balancing of differentiation and proliferation driven by an expanding pool of progenitor cells. In the mouse pancreas, lineage tracing at the population level has shown that the expanding pancreas progenitors can ...

Development of bioactive hydrogel capsules for the 3D expansion of pluripotent stem cells in bioreactors

Matthias Lütolf, Yoji Tabata

Pluripotent stem cells hold great promise for many pharmaceutical and therapeutic applications. However, the lack of scalable methodologies to expand these cells to clinically relevant numbers is a major roadblock in realizing their full potential. To addr ...

In Vitro Pancreas Organogenesis from Dispersed Mouse Embryonic Progenitors

Anne Grapin-Botton, Chiara Greggio, Filippo De Franceschi

The pancreas is an essential organ that regulates glucose homeostasis and secretes digestive enzymes. Research on pancreas embryogenesis has led to the development of protocols to produce pancreatic cells from stem cells. The whole embryonic organ can be c ...

Loss of transcriptional control over endogenous retroelements during reprogramming to pluripotency

Didier Trono, Priscilla Turelli, Evaristo Jose Planet Letschert, Marc Samuel Friedli, Adamantia Kapopoulou, Bastien Mangeat, Gabriela Ecco, Benjamin Rauwel, Carmen Maria Unzu Ezquerro

Endogenous retroelements (EREs) account for about half of the mouse or human genome, and their potential as insertional mutagens and transcriptional perturbators is suppressed by early embryonic epigenetic silencing. Here, we asked how ERE control is maint ...
