Correlation between age, somatic expansion, ploidy and nuclearity in DM1 knock-in mice

Age*	1 – 3 months			12 – 25 months
Somatic Expansion	no			yes
Ploidy	2n	4n	8n	2n	4n	8n
	54 ± 9%	45 ± 8%	2 ± 2%	45 ± 5%	43 ± 3%	13 ± 3%
Nuclearity	100% mononuclear	80% binuclear	n.d.	100% mononuclear	80% binuclear	80% binuclear

* n = 5 for 1–3 months-old mice and n = 8 for 12–25 months-old mice; n.d., not determined
