L1 subfamily and tissue distributions of L1 ASP transcripts. a Evolutionary age of L1 subfamilies indicates a role for most L1 evolutionary subtypes in genesis of L1 ASP transcripts. b Characterization of source material used for ESTs cDNA that support L1 ASP transcripts. c Tissue source for ESTs supporting L1 ASP transcripts identified in hyper-proliferative or cancerous samples. d Normal tissue sources for ESTs used to identify L1 ASP transcripts
