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...

Elife. 2020 Oct 16;9:e55212 Abstract: https://pubmed.ncbi.nlm.nih.gov/33063669/In brief: In some species, growth plate and articular cartilage are not separated by secondary ossification centers. Here, the authors used mathematical modeling, ex vivo models and biophysical tests and indirectly demonstrate that secondary ossification centers evolved in order to protect the g...
