Table 3. Alternative splicing of CD90⁺CSCs and CD90⁺ NTSCs.

	CD90+CSCs	CD90+NTSCs
Alternative 3′ splice site	127	77
Alternative 5′ splice site	115	74
Alternative first exon	23	15
Alternative last exon	11	11
Mutually exclusive exon	1.7	0.3
Intron retention	44	23
Exon skipping	61	45
Total number of alternative splicing events	383	245

Events are expressed as means. More alternative splicing events were observed in CD90⁺CSCs as compared with CD90⁺NTSCs (P<0.05).
