Any type of…, NLM Chondrocytes are derived from pluripotent mesenchymal stem cells (MSC), which are able to differentiate into chondrocytes and osteocytes. Nevertheless, there still are some open questions about the complex process of MSC differentiation involving different transcription factors and signaling pathways, which will be discussed in this review. d) cavities.

Involvement of mitochondrial biogenesis during the differentiation of human periosteum-derived mesenchymal stem cells into adipocytes, chondrocytes and osteocytes. Osteoclast precursors differentiate into osteoclasts through Rankl-Rank signaling. Osteocyte death ultimately results in necrosis; DAMPs are released to the bone surface and promote the production of proinflammatory cytokines, which induce Rankl expression, and osteoclastogenesis is further enhanced.
