Relative expression of P2Y₁, P2Y₆ and P2Y₁₂ receptors in astroglial cultures

% Highly enriched astroglial cultures
	tP2Y1	mP2Y1	tP2Y6	tP2Y6 86 kDa	mP2Y6	mP2Y6 86 kDa	tP2Y12
Co-cultures	93 ± 14 (5)	121 ± 22 (3)	129 ± 19 (4)	245 ± 20* (4)	176 ± 12* (3)	200 ± 57* (3)	93 ± 11 (3)

Quantification by densitometry of P2Y₁, P2Y₆ and P2Y₁₂ receptors total expression (tP2Y₁, tP2Y₆, tP2Y₁₂) and the membrane fractions of P2Y₁ and P2Y₆ receptors (mP2Y₁, mP2Y₆). The expression of the 86 kDa band of P2Y₆ receptors was also compared between cultures. Values are means ± SEM from (n) cultures represented in percentage of the expression observed in highly enriched astroglial cultures. Statistical analysis was performed using one-way repeated measures analysis of variance followed by Bonferroni multiple comparison test

*P < 0.05, significant differences from highly enriched astroglial cultures
