Immunodetection of quail germ cells using quail specific antibody (QCPN, a nuclear marker) in testes of transplanted chicken recipients. (A) Seminiferous tubules of adult chicken without interspecific transplantation and, consequently, without labeling for quail cells (negative control). (B) Seminiferous tubules of adult quail showing nuclear labelling of germ cells with QCPN (positive control). (C) Seminiferous tubules of adult chicken recipient transplanted with spermatogonia-enriched cell fraction from quail and exhibiting nuclear labeling of germ cells.
