Table 3.

The number of proteins identified in LCM islet and in LCM acinar tissue against the Beta Cell Gene Atlas-BCGA (Transcriptome expression values for each gene were ranked on a scale of 0-100. Cutoffs for expression level are as follows: enriched (>75), moderate (50-75), low (25-50) and no expression (<25) [40])

	Expression level	BCGA Duct	BCGA Exocrine	BCGA Pancreatic islets	BCGA β- cell
LCM islets	Enriched	288	965	997	556
	Moderate	553	46	12	200
	Low	168	25	16	93
	No expression	88	61	66	248
LCM acinar tissue	Enriched	214	644	655	397
	Moderate	348	19	7	124
	Low	75	7	8	45
	No expression	67	34	34	138
Proteins only identified in LCM islets	Enriched	93	394	423	187
	Moderate	292	30	7	95
