Novel bioprinting method using a pectin based bioink.

One major challenge of bioprinting is to develop a viable bioink to act as an extracellular matrix. This study investigated a novel method for bioprinting using a pectin based bioink. Besides pectin, Pluronic® F-127 was incorporated into the bioink to obtain the desired shape during the initial bioprinting process at 37∘C. Once an object was printed it was treated with Ca2+ (pectin cross-linker) to create the final tissue/organ structure. The results indicated that pectin/Pluronic® F-127 is a potential bioink. Moreover, this methodology provides a novel and fast approach for bioprinting.
