摘要: Three-dimensional (3D)
bioprinting technology has great potential for application in the treatment of cartilage
defects. However, the preparation of biocompatible and stable bioinks is still
a major challenge. In this study, decellularized extracellular matrix (dECM)
of soft tissue was used as the basic material to prepare the bioink. Our
results showed that this novel dECM-derived bioink had good printing
performance and comprised a large number of fine nanofibers. Biological
characterization revealed that the bioink was compatible with the growth of
chondrocytes and that the nanofibrous structure greatly promoted cell
proliferation. Histological and
immunohistochemical analyses showed that
the in vitro printed cartilage displayed the presence of characteristic cartilage
lacunae. Thus, a new preparation method for dECM-derived bioink with potential
application in generation of cartilage was developed in this study.
