Fig. 5From: Effects of secreted frizzled-related protein 1 on proliferation, migration, invasion, and apoptosis of colorectal cancer cellsCell invasion analysis of SFRP1 knockdown in caco-2 cells and SFRP1 overexpression in sw1116 cells. SFRP1 knockdown caco-2 cells and sw1116 cells overexpressing SFRP1 were seeded in the upper chamber of transwell filters. After 24 h incubation, the top of the filters was scraped and cells that Matrigel-invaded the filters were fixed and stained. Representative images of invading cells in one field were shown. Invading cell number was counted in five random fields under a microscopeBack to article page
