Regulatory mechanism for the proliferation and differentiation of growth plates / 中华实用儿科临床杂志

ABSTRACT

The growth plate (cartilage tissue) is the key to bone development and linear growth.However, as the adolescence proceeds, the proliferation capacity of the growth plate will be continuously consumed, and finally the growth plate will be closed.A variety of regulatory factors control chondrocyte proliferation and differentiation through different mechanisms.Endocrine regulators (including growth hormone, insulin-like growth factor, thyroxine, sex hormone, glucocorticoid, etc.) and transcription factors play an important role in regulating the development of growth plates through systematic modulation.In addition, such local regulatory factors as Indian hedgehog protein, parathyroid hormone-related peptide, bone morphogenetic protein and fibroblast growth factor also regulate the development of the growth plate.In this paper, the regulatory mechanism for chondrocyte proliferation and differentiation was summarized.
