Quantification of lipids in the membrane of Retics and RBCs in five independent experiments with five different donors.

		RETIC	RBC	p-value
−	PC	24.0 ± 1.3	20.5 ± 1.1	0.007*
	LPC	1.2 ± 0.2	1.2 ± 0.2	0.910
+	SM	17.2 ± 0.8	19.8 ± 1.0	0.015*
	PE	7.1 ± 2.1	7.5 ± 0.9	0.539
−	PS	4.2 ± 0.5	3.5 ± 0.5	0.010*
	PI	0.7 ± 0.2	0.7 ± 0.2	0.559
+	Chol	45.6 ± 1.2	46.8 ± 0.8	0.041*

Values are mean ± standard deviation and are expressed as mol% over the total lipids analyzed in each sample of Retics or RBCs. The symbols in the left column indicate whether the quantity of a given lipid increases (minus) or decreases (plus) from Retic to RBC. To the right, the p values obtained from the statistical elaboration of the data with the Student’s t-test are shown. An asterisk indicates where p < 0.05.
