[Notch signaling in bone formation and related skeletal diseases].

Notch signaling is highly conserved in evolution and regarded as a key factor in cell fate determination. It mediates cell-to-cell interactions that are critical for embryonic development and tissue renewal, and is involved in the occurrence and metastasis of neoplasm. Recent researches have found that such signaling plays an important role in modulating the differentiation of chondrocytes, osteoblasts and osteoclasts. Dysfunction of Notch signaling can result in many skeletal diseases such as bone tumor, disorders of bone development or bone metabolism.
