Confirmation of the decellularization process. Cellular and nuclear content was tested via DAPI staining. Bright, punctate spots (arrows) indicating nuclei a can be seen before decellularization but b are absent after decellularization (blue background staining of tissue is still present). High-magnification images of nuclear staining in both c control and d decellularized menisci. (All scale bars = 100 μm)
