Low-Power Ultrasounds as a Tool to Culture Human Osteoblasts inside Cancellous Hydroxyapatite

Table 1

Amount of extracellular matrix constituents inside hydroxyapatite.

	Matrix protein total coating after 22 days of culture in fg/(cell × disk)
	Static culture	Ultrasonic culture	Ultrasonic /Static
Decorin	5.58 ± 0.22	15.25 ± 0.42	2.73-fold
Osteocalcin	1.79 ± 0.33	5.76 ± 0.39	3.22-fold
Osteopontin	1.75 ± 0.73	3.04 ± 0.47	1.74-fold
Type-I collagen	3.72 ± 0.49	16.85 ± 0.95	4.53-fold
Type-III collagen	4.59 ± 0.13	11.04 ± 0.71	2.40-fold
