Skin-graft histocompatibility within Regional Poultry Research Laboratory inbred chicken lines

Skin grafts were exchanged between specific-pathogen-free chicks within the Regional Poultry Research Laboratory (RPRL) inbred lines that are characterized for retrovirus susceptibility and immunogenetic traits. Lines 61 and 63 were histocompatible whereas lines 15I4 and 15I5 were nearly histocompatible. The RPRL Line 7(2) is only histocompatible within families at present, and line 100 has considerable heterogeneity for minor histoantigens. Reaseheath Line C (RH-C) has been established at the RPRL and its histocompatible. Numerous males in lines 6(1), 6(3), 15I4, and RH-C are able to reject female grafts containing the female-specific histoantigen. Two Ea-B alleles in 15I4 previously detected by blood-typing determined rapid skin graft rejection.
