A Osteoblast proliferation in terms of DNA release in ng/mL. B ALP activity in μU/mL. C Collagen type I in ng/mL. D IL-6 secreted by osteoblasts in μg/mL. Letters indicate intragroup non-statistically significant differences between two consecutive times. Differences within groups are identified with a symbol. Comparisons of ALP activity could not be stablished on the clot lysate because of a lack of sample on the control group
