(a) Relative DNA content of adipose stem cells cultured for 7, 14, and 28 d on different materials measured with CyQUANT proliferation assay kit. The optical density (OD) was measured at 480/520 nm. Results are expressed as mean ± standard deviation (SD), n = 4. *P < 0.05 with respect to corresponding composite implant (PLA70/β-TCP). (b) Alkaline phosphatase (ALP) activity of human adipose stem cells cultured for 7, 14, and 28 d on different materials measured with ALP activity kit. Results are expressed as mean ± SD, n = 4. *P < 0.05 with respect to corresponding PLA70/β-TCP.
