Figure 2. Effect of co-culture with CTNS-expressing cells on cystine content of mutant CTNS cells.

Figure 2

(a) Cystine content of CTNS(−/−) fibroblasts co-cultured with increasing amounts of wildtype amMSC. (b) Cystine content of GFP-tagged CTNS(−/−) ciPTEC isolated by FACS after co-culture with unlabelled wildtype amMSC, mutant ciPTEC or CTNS-corrected ciPTEC as donors. Statistical significance is indicated by the corresponding p-value.
