    Analysis of Hr alleles in homozygous (H) and wild-type (W) HR mice. The normal (wild-type) Hr allele is ~19 kbp in length and consists of 19 exons. A total of 15 overlapping PCRs covering the entire Hr coding sequence revealed that an insertion mutation was localized in intron 6 of the Hr x allele. KOD FX neo was used for PCR amplification of regions 2–7, and HotStarTaq was used for PCR of other regions. PCRs shown in gray typeface (1, 2, 4, 6, 9, 12, 14, 15), no difference between homozygous and wild-type HR mice. PCRs shown in black typeface (3, 5, 7, 8, 10, 11, 13), no band or different bands were obtained in homozygous HR mice. Six agarose gel electropherograms show the band patterns of all PCRs. The primer sets used were: (1) F224 and R1151, (2) F193 and R1873, (3) F193 and R2433, (4) F2463 and R3455, (5) F1843 and R2433, (6) F2052 and R2433, (7) F1843 and R2078, (8) F1843 and R1972, (9) F1913 and R2078, (10) F1843 and Int6-R1458, (11) F1843 and Int6-R979, (12) Int6-F1290 and R1972, (13) F1843 and Int6-R850, (14) F1843 and Int6-R642, and (15) F1843 and Int6-R539. The primer sequences and elongation time are shown in Tables 1 and 2 , respectively. The primer positions for long PCR shown in Fig. 2 are also indicated in this figure.

    PCR for genotyping Hr alleles in HR and Hos:HR-1 mice. (A) Primer positions (primer sequences are shown in Table 1 ). PCR using the primers mHR-int6-S607 (S607) and mHR-int6-R850 (R850) produces 244-bp amplicons from wild-type alleles ( Hr , + in Fig. 3B ) only. PCR using the primers mHR-int6-S776 (S776) and mHR-int6-R850 (R850) produces 275-bp amplicons from mutant alleles ( Hr hr , hr in Fig. 3B ) only. (B) Zygosity determination by PCR. Zygosities of Hr alleles were determined by PCR using three primers (S607, S776, and R850) simultaneously. If only 275-bp amplicons were produced, the mice were taken to be homozygous ( Hr hr / Hr hr ). If only 244-bp amplicons were produced, the mice were wild-type ( Hr / Hr ). If both amplicons were produced, the mice were heterozygous ( Hr / Hr hr ). Electropherograms of PCR products indicate the zygosities of homozygous, heterozygous, and wild-type HR mice as well as homozygous Hos:HR-1 mice.

    a. Detection of spiked KPL-4 cells and cells after i.v. injection. 10 cells were spiked into 100 μl or 1 ml of native murine blood samples. Cells of the KPL-4 line stably expressed EpCAM, Her2 and the housekeeping-genes for up to 4 h. The cells could be detected by AdnaTest and without antibody enrichment (a.). 100,000 cells of the KPL-4 cell line were injected into the tail vein of native mice. Tumour cells could not be detected by the AdnaTest, whereas human mRNA was visible without antibody enrichment for up to 4 h after injection. The detected cells showed serial changes and reduced EpCAM expression already 30 min after i.v. injection (b.). b. Tissue analyses for human mRNA after injection of 100,000 KPL-4 cells into the tail vein. Tissues were homogenised and RNA was purified followed by cDNA synthesis and PCR reaction. Human breast cancer cells detectable in the lungs and one liver were positive for EpCAM and Her2 expression up to 2 h after KPL-4 cell injection. c. MDA-MB-231 breast cancer cells were injected into the heart and blood was analysed for human mRNA signals. CTCs were detectable in all animals for up to 5 h after injection. The detected cells showed changes of mRNA expression including downregulation of EpCAM and MUC-1, whereas mRNA of the housekeeping-genes and mesenchymal Vimentin was visible permanently.
