Figure 6. Neonatal porcine islets in the CCCL gels were transplanted subcutaneously and retrieved after 4 (C and D), 7 (E and F), and 28 (G and H) days. Pre-transplantation grafts were also collected (A and B). The grafts were fixed and paraffin-embedded; sections were stained for insulin, hemotoxylin and eosin (A, C, E, and G) and glucagon, hemotoxylin and eosin (B, D, F, and H). Arrows indicated insulin (A, C, E, and G) or glucagon (B, D, F, and H) positive cells. Scale bars for A-F are 100 µm and for G and H are 50 µm.
