Article Synopsis
- The mammalian pancreas has three key parts: exocrine acini and ducts, along with endocrine islets, all originating from a common progenitor during development.
- Researchers created 18 human fetal pancreas organoid lines from samples between 8-17 weeks of gestation, with four lines showing the ability to produce all three cell types while thriving in culture for over two years.
- Single-cell RNA sequencing revealed LGR5 cells as crucial developmental stem cells, indicating that these organoids are capable of long-term growth and can differentiate into acinar, ductal, and endocrine cells.
Background: Previous research highlights persistent differential attainment by ethnicity in medical education, wherein the perceived inclusiveness significantly influences ethnic minority students' and trainees' outcomes. Biased organizational practices and microaggressions exacerbate the challenges faced by ethnic minorities, leading to lower academic performance and higher dropout rates. Consequently, understanding ethnic minority GP-trainees' experiences and perspectives regarding relevant educational aspects is crucial for addressing these disparities and cultivating a more inclusive environment within medical education.

- Mitochondrial disease is a rare condition currently lacking approved treatments, with sonlicromanol being a promising candidate that modifies key metabolic and inflammatory pathways.
- A Phase 2b study was conducted to evaluate sonlicromanol's safety and efficacy in adults with a specific genetic mutation, involving both a randomized controlled trial (RCT) and a long-term extension study.
- While the primary endpoint of the RCT didn't show significant results, there were indications of improvement in certain cognitive and emotional assessments among patients who were more affected at baseline.
Carcinogenesis results from the sequential acquisition of oncogenic mutations that convert normal cells into invasive, metastasizing cancer cells. Colorectal cancer exemplifies this process through its well-described adenoma-carcinoma sequence, modeled previously using clustered regularly interspaced short palindromic repeats (CRISPR) to induce four consecutive mutations in wild-type human gut organoids. Here, we demonstrate that long-term culture of mismatch-repair-deficient organoids allows the selection of spontaneous oncogenic mutations through the sequential withdrawal of Wnt agonists, epidermal growth factor (EGF) agonists and the bone morphogenetic protein (BMP) antagonist Noggin, while TP53 mutations were selected through the addition of Nutlin-3.
