Engineering next generation organoids through guided stem cell self-organisation

Mikhail Nikolaev

One of the long-standing goals in the field of tissue engineering is the fabrication of de novo tissues or even organs to provide better tissue models for basic research and drug discovery, and to alleviate a shortage of donor organs in the future. Resear ...

Intestinal organoid cocultures with microbes

Devanjali Dutta

This protocol comprises various methods to coculture organoids (particularly human small intestinal and colon organoids) with microbes, including microinjection into the lumen and periphery of 3D organoids and exposure of organoids to microbes in a 2D laye ...

High-content, targeted RNA-seq screening in organoids for drug discovery in colorectal cancer

Maxim Norkin, Paloma Ordonez Moran

Organoids allow the recapitulation of intestinal homeostasis and cancerogenesis in vitro; however, RNA sequencing (RNA-seq)-based methods for drug screens are missing. We develop targeted organoid sequencing (TORNADO-seq), a high-throughput, high-content d ...

Next-generation cancer organoids

Matthias Lütolf, Nicolas Antoine Vincent Broguiere

Organotypic models of patient-specific tumours are revolutionizing our understanding of cancer heterogeneity and its implications for personalized medicine. These advancements are, in part, attributed to the ability of organoid models to stably preserve ge ...

Roles of Epigenetic Dysregulation in Cancer Progression and Metastasis

Mohammad Sadegh Saghafinia

Nearly all the cells of an organism share the same DNA sequence or genome, and yet they show different phenotypes and carry out different functions. This diversity is made possible by a verity of molecular modifications acting on the DNA sequence that coll ...

NCoR1 Protects Mice From Dextran Sodium Sulfate Induced Colitis by Guarding Colonic Crypt Cells From Luminal Insult

Johan Auwerx

BACKGROUND & AIMS: Colonic stem cells are essential for producing the mucosal lining, which in turn protects stem cells from insult by luminal factors. Discovery of genetic and biochemical events that control stem cell proliferation and differentiation can ...

Monitoring alpha-synuclein oligomerization and aggregation using bimolecular fluorescence complementation assays: What you see is not always what you get

Hilal Lashuel, Nathan Alain Denis Riguet, Bryan Frey, Abdelrahman Mohammed Adel Elsaeed Mansour AlOkda

Bimolecular fluorescence complementation (BiFC) was introduced a decade ago as a method to monitor alpha-synuclein (alpha-syn) oligomerization in intact cells. Since then, several alpha-syn BiFC cellular assays and animal models have been developed based o ...

Conservative management of retinoblastoma: Challenging orthodoxy without compromising the state of metastatic grace. "Alive, with good vision and no comorbidity"

Paul Joseph Dyson

Retinoblastoma is lethal by metastasis if left untreated, so the primary goal of therapy is to preserve life, with ocular survival, visual preservation and quality of life as secondary aims. Historically, enucleation was the first successful therapeutic ap ...

Value Creation in Precision Medicine: Acknowledging the Need to Devise New Ways to Measure. The Value of Healthcare

Anjali Devi Vanapilli Nursimulu

Precision medicine holds the promise of bringing the right treatment to the right patient at the right time with the upside of reduced undesirable effects. But the impact on healthcare costs are not clear. While targeting of conventional drugs through prec ...

Characterization of cancer stem cell subpopulations from patient-derived xenografts of advanced prostate cancer

Marina Bice Manuela Menna, Markus Germann

Androgen-deprivation therapy is the standard treatment for prostate cancer. Despite the initial response, a fraction of cases manifest progression to castration-resistant prostate cancer. PCa recurrence is possibly due to androgen-independent cancer stem c ...
