Organogenesis is a complex process that relies on a dynamic interplay between extrinsic factors originating from the microenvironment and tissue-specific intrinsic factors. For pancreatic endocrine cells, the local niche consists of acinar and ductal cells as well as neuronal, immune, endothelial, and stromal cells. Hematopoietic cells have been detected in human pancreas as early as 6 post-conception weeks, but whether they play a role during human endocrinogenesis remains unknown.

Article Synopsis
  • Human pluripotent stem cells (hPSCs) can potentially become insulin-producing β cells, which are important for diabetes treatment, but current differentiation methods are not very effective.
  • Researchers found that using selective tankyrase inhibitors like WIKI4 improves the differentiation of hPSCs into pancreatic progenitors, leading to better development of islet-like cells.
  • These advancements enhance our understanding of pancreatic cell development and offer a new approach for creating pancreatic cells for research and potential diabetes therapies.

Epithelial-to-mesenchymal transition (EMT) is an orchestrated event where epithelial cells progressively undergo biochemical changes and transition into mesenchymal-like cells by gradually losing their epithelial characteristics. EMT plays a crucial pathologic role in renal abnormalities, especially renal fibrosis. A number of bench studies suggest the potential involvement of renin-angiotensin-aldosterone system (RAAS) in renal EMT process and associated renal abnormalities.

The activation of peroxisome proliferator-activated receptor α (PPARα) is a key pharmacological drug target for dyslipidemic management. Dyslipidemia is associated with abnormal serum lipid profiles viz. elevated total cholesterol, high triglyceride, elevated low-density lipoprotein cholesterol, and reduced high-density lipoprotein cholesterol levels.
