Figure 4: Teratoma formation from injected pESL cells.
From: Derivation of Porcine Embryonic Stem-Like Cells from In Vitro-Produced Blastocyst-Stage Embryos
(a) Gross image of the mouse showing subcutaneous teratomas in the neck and dorsal flank regions. (b) Tumors removed from mouse (a) after 90 days injection. (c–f) Three germ layers present in teratomas derived from the pESL cell line at passage 21. The images of H&E-stained sections showing representative endoderm (d), branched glands and duct, mesoderm (c,f), striated muscle and smooth muscle and ectoderm lineage (e), neural rosette. Scale bar = 100 um.
