Our hCSs also showed higher mRNA levels of the NPC markers MKI67 and PAX6 (median FC batch-1 = 2.4, median FC batch-12 = 3.9), but lower mRNA expression levels of the NPC-proliferation markers TOP2A and High Mobility Group Box 2 (HMGB2) (median FC batch-1 = 0.3, median FC batch-12 = 0.5). Here, TOP2A is linked to nasopharyngeal carcinoma.
