The original version of this Article contained an error in the legend of Figure 2.


“(a–d) Histological images of the outer bottom group at 1 week posttransplantation. Asterisks indicate the transplanted chondrocyte layer. (a) HE staining. (b) An enlarged view of the area indicated by the black rectangle in Fig. 1a. Capillaries are indicated by red arrowheads with enlarged views at the corners. (c,d) An immunofluorescent image of the same sample as in Fig. 1a. Asterisks indicate the transplanted chondrocyte layer. Alexa 594: F4/80, DAPI: nucleus. (d) An enlarged view of the area indicated by the yellow rectangle in (c). F4/80-positive cells (yellow triangle) were observed among the transplanted chondrocytes. (eg) Immunofluorescent images of the outer bottom group sample at 2 weeks posttransplantation. Alexa 594: F4/80, DAPI: nucleus. Asterisks indicate the transplanted chondrocyte layer, and white circles indicate the host cell layer. (f,g) Enlarged views of areas indicated by yellow rectangles in (d).”
