Metabolic reprogramming in skeletal cell differentiation
The human skeleton is a multifunctional organ made up of multiple cell types working in concert to maintain bone and mineral homeostasis and to perform critical mechanical and endocrine functions. From the beginning steps of chondrogenesis that prefigures most of the skeleton, to the rapid bone accrual during skeletal growth, followed by bone remodeling of the mature skeleton, cell differentiation is integral to skeletal health. While growth factors and nuclear proteins that influence skeletal cell differentiation have been extensively studied, the role of cellular metabolism is just beginning to be uncovered. Besides energy production, metabolic pathways have been shown to exert epigenetic regulation via key metabolites to influence cell fate in both cancerous and normal tissues. In this review, we will assess the role of growth factors and transcription factors in reprogramming cellular metabolism to meet the energetic and biosynthetic needs of chondrocytes, osteoblasts, or osteoclasts. We will also summarize the emerging evidence linking metabolic changes to epigenetic modifications during skeletal cell differentiation.
期刊介绍:
Established in 2013, Bone Research is a newly-founded English-language periodical that centers on the basic and clinical facets of bone biology, pathophysiology, and regeneration. It is dedicated to championing key findings emerging from both basic investigations and clinical research concerning bone-related topics. The journal's objective is to globally disseminate research in bone-related physiology, pathology, diseases, and treatment, contributing to the advancement of knowledge in this field.
