Inverse relationship between the protein expression levels of CD44 and CD146 in human normal and breast tumor tissues

	Intensity of immunostaing in normal breast tissue		Intensity of immunostaing in the breast adenocarcinomas grade 3 tumors
Patient number	CD44	CD146	CD44	CD146
1	+	+++	+++	+
2	+	++	+++	+
3	+	+++	+++	+
4	+	+++	+++	+

A simple comparison of the intensity of immunostaining was adopted using 1+ for low expression, 2+ for intermediate expression and 3+ for high expression, and the data was summarized in a table
