Pancreas organogenesis depends on proper interactions of endoderm-derived epithelial cells, which will form the exocrine and endocrine cells of the adult organ, with their surrounding mesenchymal layer. Research on the role of pancreatic mesenchyme, pioneered by Golosow and Grobstein in the 1960's, revealed these cells regulate multiple events during pancreas development. Still, much is unknown regards the molecular basis of epithelial-mesenchymal interactions in this process. Here, we review in vivo and ex vivo approaches to study mesenchymal requirements for mammal pancreas organogenesis, and how gained knowledge is being translated toward the development of cell replacement therapy for diabetes.

Rare earth elements are integral to modern technology, but their increasing environmental distribution due to anthropogenic activities poses potential health risks to humans. This study utilized zebrafish as a model to assess developmental and locomotor performance effects of europium and samarium. Exposure to Eu or Sm induced a reduction in heart rate, growth inhibition, and morphological deformities.

The spatial organization of cells within a tissue is dictated throughout dynamic developmental processes. We sought to understand whether cells geometrically coordinate with one another throughout development to achieve their organization. The pancreas is a complex cellular organ with a particular spatial organization.

Pleiotrophin (PTN) is crucial for embryonic development and pancreas organogenesis as it regulates metainflammation, metabolic homeostasis, thermogenesis, and glucose tolerance. Pleiotrophin deletion is associated with a lipodystrophic phenotype in which adipose tissue plasticity is altered in late life. This study explored the impact of pleiotrophin deletion on pancreatic morphology and function in later life.

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.
