To read the full abstract: Science. 2017; 357(6346)Current textbooks teach that adrenergic chromaffin cells of the adrenal medulla originate from a sympathoadrenal cell lineage of the neural crest nearby the dorsal aorta. Here, Furlan et al. demonstrate a novel origin of these neuroendocrine cells of the medulla arising predominantly from Schwamm cell precursors (SCP) of peripheral nerves. Prev...

Abstract: Nature. 2019 Mar;567(7747):234–238.In brief: In this article, the authors present evidence that the murine epiphyseal growth plate develops a postnatal stem cell niche with monoclonal properties, that are able to self-renew. They thereby challenge the concept of a continous depletion of progenitor cells as a limiting factor for bone growth.<p class="abste...
