Effect of SFRP-1 on number of osteoclasts and TRAP-positive mononuclear cells^*

Treatments (ng/ml)	Osteoclasts^**	Mononuclear cells^**
CSF-1 (75)+RANKL(30)	2068 ± 370 a	299 ± 114 B
CSF-1(75)+RANKL(30)+SFRP-1(100)	1741 ± 255 b	536 ± 180 B
CSF-1(75)+RANKL(30)+SFRP-1(500)	1320 ± 172 c	827 ± 205 B
CSF-1(75)+RANKL(30)+SFRP-1(1000)	868 ± 65 d	1593 ± 751 A
CSF-1(75)+RANKL(30)+SFRP-1(500)+RANKL(50)	1966 ± 358 ab	678 ± 297 B

Based on cell counting per well in 12-well plate (4 cm²).

^**

Cell numbers followed by different letter (s) within a column indicated a significant difference at P≤0.05 with the LSD test. For example, under “osteoclasts” “a” differs from all others under the column except for “ab”.
