Purpose: To explore the expression of a disintegrin and metalloproteinase 10 (ADAM10) during mouse's development of cranial base synchondrosis.
Methods: Histological and biochemical method including alcian blue-alizarin red staining, IHC, ICC and Western blot were applied to observe and analyze the expression of ADAM10 in mouse cranial base.
Results: The spheno-occipital synchondrosis and spheno-ethmoid synchondrosis were of similar histological structure, including resting zone, proliferative zone and hypertrophic zone. ADAM10 was expressed widely in synchondrosis,especially in the hypertrophic zone. During development of cranial base, ADAM10 was highly expressed from embryo period to infantile period, while there was a huge decrease when it came to adulthood. As an excellent cell line to mimic chondrogenesis, ATDC5 expressed ADAM10 in cytoplasm, particularly around the nucleus.
Conclusions: The expression of ADAM10 during mouse's development of cranial base synchondrosis is spatiotemprally different.
