Spermatogonia identified by expression of UCH-L1 in donor and grafted tissue. A, Three-month-old donor tissue. B, Six-month-old donor tissue. C, Graft from 3-month-old donor recovered from untreated mouse. D, Graft from 6-month-old donor recovered from untreated mouse. E, Graft from 3-month-old donor recovered from gonadotropin-treated mouse. F, Graft from 6-month-old donor recovered from gonadotropin-treated mouse. Fewer spermatogonia were present in grafted tissue recovered from treated and untreated mice, compared with donor tissue. Bar, 50 μm.
