SFRP4 stained cell area ratio in normal uterine smooth muscle and uterine leiomyosarcoma tissues.

Tissue	Total area, µm2	Stained area, µm2	Ratio, %
Normal uterine smooth muscle 1	579,907	329,900	57
Normal uterine smooth muscle 2	288,917	235,857	82
Normal uterine smooth muscle 3	1,062,726	569,027	54
Normal uterine smooth muscle 4	634,039	350,073	55
Uterine leiomyosarcoma 1	2,675,916	1,282,439	48
Uterine leiomyosarcoma 2	2,328,849	2,273,09	10
Uterine leiomyosarcoma 3	2,156,167	290,801	13

To confirm the expression of SFRP4 by immunostaining, the number of stained cells was measured in 4 cases of normal uterine smooth muscle and 3 cases of uterine leiomyosarcoma, and the area ratio was calculated. SFRP, secreted frizzled-related protein.
