TABLE 5.

Conventional karyotypes of USC^TA+ and USC^TA- clones in the 20- and 50-years age groups at early and late passages.

	Age at 20s group		Age at 50s group
	USC clones	Karyotypes	USC clones	Karyotypes
USC ^TA+	A35 (p4)	46, XY	J29 (p4)	46, XY
USC ^TA+	A35 (p12)	46, XY	J29 (p12)	46, XY
USC ^TA−	A42 (p4)	46, XY	J18 (p4)	46, XY
USC ^TA−	A42 (p8)	46, XY	J18 (p8)	46, XY

Notes: A35-clone (USCs^TA+, RTA: 45.60) and A42 clone (USCs^TA−, RTA: negative) were both isolated from one donor (male, 27-year-old); J29 (USCs^TA+, RTA:46.6) and J18 (USCs^TA−, RTA: negative) were isolated from another donor (male, 55 year-old).
