(A) Gross observation of the transplants at days 3, 15, and 30. Conventional pellet culture transplants (dotted black outlines) were placed into the contralateral portion of the vascularized transplants (blue outlines). (B) Alcian blue–stained sections of the vascularized transplants and pellet transplants at day 60 (n = 3 independent transplantation experiments). Scale bars: 200 μm. (C) Quantification of Alcian blue–positive areas for the widest points of the sections. Data represent the mean ± SEM (n = 3, *P < 0.05).
