In agreement with our previous data [16], in vitro priming of adult NPCs with lithium chloride robustly decreased the proportion (Welch's corrected t19 = 5.16; P < 0.0001; Figure 2j) of BrdU-labeled cells coexpressing GFAP from 29.11 ± 3.04% in nonprimed transplants to 11.78 ± 1.42% in primed NPC transplants. The gene discussed is GFAP; the disease is nasopharyngeal carcinoma.
