Figure 3From: Establishment of transgene-free induced pluripotent stem cells reprogrammed from human stem cells of apical papilla for neural differentiationHistological analysis of teratomas. Images of removed teratomas from mice are shown on the left of the image panels. (A) Multi-differentiated tissues derived from SCAP iPSCs (passage (p)11) before Cre-excision. (B) Teratomas from SCAP iPSCs (p10) after Cre-excision. (A & B) (a,b) mainly neural tissues, neural rosettes (ectoderm); (c) mainly cartilage (mesoderm); (d) bone tissue (mesoderm); (e,f) mainly glandular epithelium and endodermal tissues. (scale bar: 100 μm for all histologic images. Except Bf, all histologic images use the scale bar in Ba). iPSCs, induced pluripotent stem cells; SCAP, stem cells from apical papilla.Back to article page
