Expression of MSX2, SP3, and SP6 in cultured hKSCs in presence and/or absence of FGF8 and/or SHH. hKSCs at passage 3 cultured with or without proteins for 36 h prior to immunofluorescent staining. No expression differences found among controls (a, e, i) and experimental groups treated with FGF8 (b, f, j), SHH (c, g, k), or FGF8 + SHH (d, h, l). Scale bar = 100 μm. FGF8 fibroblast growth factor 8, SHH Sonic hedgehog
