To test for effectiveness of lyophilized cells, which can be stored at ambient temperature for long periods of time, we tested the identical regimen of two oral gavages per week for 2 months in haemophilia A mice, which were challenged with 4 weekly intravenous injections of B domain‐deleted (BDD) human FVIII (1 IU/dose) during the second month of the experiment (Figure 3a). This evidence concerns the gene F8 and hemophilia A.
