Induction of functional dopamine neurons from human astrocytes in vitro and mouse astrocytes in a Parkinson's disease model

Cell replacement therapies for neurodegenerative disease have focused on transplantation of the cell types affected by the pathological process. Here we describe an alternative strategy for Parkinson's disease in which dopamine neurons are generated by dir ...

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

Lilia Salimova

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, Alexandra Iouranova, Michaël Imbeault, Julien Paul André Pontis, Haoyi Wang

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 ...

Polycomb Complex PRC1 Preserves Intestinal Stem Cell Identity by Sustaining Wnt/beta-Catenin Transcriptional Activity

Paloma Ordonez Moran

Polycomb repressive complexes (PRCs) are among the most important gatekeepers of establishing and maintaining cell identity in metazoans. PRC1, which plays a dominant role in this context, executes its functions via multiple subcomplexes, which all contrib ...

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

Anne Grapin-Botton, Laurence Anne E Lemaire, 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 ...

Venus trap in the mouse embryo reveals distinct molecular dynamics underlying specification of first embryonic lineages

Didier Trono, Anna Claire Groner

Mammalian development begins with the segregation of embryonic and extra-embryonic lineages in the blastocyst. Recent studies revealed cell-to-cell gene expression heterogeneity and dynamic cell rearrangements during mouse blastocyst formation. Thus, mecha ...

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

Filippo De Franceschi, Anne Grapin-Botton, Chiara Greggio

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 ...
