Relative apelin and APJ expression in normal pancreas

	Acini	Islets	PSCs*
	Mouse
Apelin	1.4	0.6	12.5
APJ	1.2	0.3	1.3
	Human
Apelin	0.03	1.0	19.0
APJ	5.1	10.0	0.1

Apelin and APJ mRNA and 18S rRNA levels were measured by real-time RT-PCR; apelin and APJ mRNA levels are normalized to 18S rRNA levels. PSCs, pancreatic stellate cells.

^*Isolated by outgrowth method.
