Extended Data Fig. 1: Pathogenic surveillance of the donor pig.

a, The PCR combined with gel electrophoresis detecting the presence of PCMV in the PBMCs of the recipient and the xenograft. b, The PCR combined with gel electrophoresis detecting the presence of PERV as well as microchimerism in the PBMCs of the recipient and the xenograft. PERV-ABC, the sequence shared by PERV-A, PERV-B and PERV-C. PERV-C, the sequence specifically belongs to PERV-C. RPP30 was used as the control gene. NTC, no template control. For gel source data, see Supplementary Fig. 1. Extended Data Fig. 1a,b contains 1 biological and technical repetition, and 3 independent experiments were carried out.
