Figure 8. Electrophoresis of amplicons obtained after reverse transcription of mRNAs extracted from cultured cells. Primers used for PCR bracket selectively the complementary sequences of CK3, CK19, vimentin, ABCG2, and delta N p63α. RNAs were extracted after 3 weeks of cultures of A: superficial limbal explants, B: full-thickness limbal explants, and C: stromal explants.
