Fig. 2From: Inhibitory effects of sodium pentosan polysulfate on formation and function of osteoclasts derived from canine bone marrowNaPPS inhibits bone resorption and actin ring formation by concentration gradient. Canine BMMs, cultured with M-CSF (25 ng/mL) and RANKL (50 ng/mL) for 7 days with or without indicated doses of NaPPS. a The cells were washed and the resorption pits were counted. b The numbers of pits were analyzed with Image-J software. c Cells were fixed, stained for F-actin formation (top) and d osteoclasts with actin ring were counted (bottom). Scale bar- 200 μm. Column indicates means ± SE of three experiments performed in triplicate. Means with *are significantly different from 0 μg/mL of NaPPS (*p < 0.05)Back to article page
