Relative change of expression of the candidate genes (a) ATCB (b) GAPDH (c) RPL13A (d) PGK1 (e) HSPCB and (f) RNA28S over successive passages in both cultures A1 and A2. The expression change was measured as 2^-Cq with the experimental calibrators marked as gray boxplots (p28 in culture A1 and p25 in culture A2)
