Researchers at Penn State have pioneered a novel approach dubbed HITS-Bio. This innovative methodology enables rapid fabrication of functional organ-like tissues, outpacing conventional methods by a factor of ten while preserving high cellular viability.
HITS Bio leverages cell clusters, also referred to as spheroids, to generate tissues boasting a density comparable to that of pristine human tissues. Unlike traditional approaches that often harm cells or move too slowly for practical applications, HITS-Bio leverages a digitally controlled nozzle array for enhanced performance.
This technique leverages multiple nozzles capable of executing three-dimensional movement, enabling the concurrent handling of spherical particles. This breakthrough enables the rapid assembly of intricate tissue architectures with tailored designs, representing a significant milestone in the field of bioprinting.
Researchers successfully created a one-cubic-centimeter cartilage tissue within 40 minutes by fabricating 600 spheroids through efficient testing. This approach significantly outperforms traditional methods while maintaining a remarkably high cell viability of over 90%. Researchers further showcased the treatment’s therapeutic capabilities by successfully repairing bone tissue in a rat model.
Researchers employed the HITS-Bio platform to biofabricate microRNA-programmed spheroids that were directly implanted into a skull wound during surgery, thereby hastening bone tissue regeneration. Following three weeks, the wound demonstrated a remarkable 91% healing progress, and an impressive 96% by the end of six weeks.
The recent development of HITS-Bio marks a significant milestone in the quest to manufacture lab-grown tissues and organs for medical applications, paving the way for groundbreaking advancements in the field. Future research initiatives will focus on seamlessly integrating blood vessels into bio-printed tissues, ultimately enhancing their functionality for potential applications in organ transplantation and more accurate disease modeling. This system has the potential to transform regenerative medicine by facilitating the rapid creation of complex tissues and organs with unprecedented ease.
