research_worker at Penn State have develop a groundbreaking three-D bioprinting technique name the High-throughput Integrated Tissue Fabrication System for Bioprinting ( HITS-Bio ). This method enable the rapid creation of functional biological tissue, achieve speed ten times faster than current approach while keep high cell viability.

HITS-Bio use cell bunch know as spheroid to manufacture tissue with a density comparable to natural homo tissue. Unlike traditional method, which often damage cell or are too decelerate for practical application, HITS-Bio employment a digitally control nozzle array. This system use multiple nozzle capable of precise three-dimensional motion, let the coincident manipulation of spheroids.

This invention enable the rapid assembly of complex tissue structure with custom-make form, devising it a significant promotion in bioprinting. In testing, the research_worker successfully manufacture a one-cubic-centimeter cartilage tissue exploitation 600 spheroid in under 40 minutes. This outpace traditional technique and retain More than 90% cell viability. The team also show the technique clinical potential by repair bone tissue in a rat model.

exploitation HITS-Bio, spheroid program with microRNA were directly print into a skull wound during surgery, accelerate bone healing. After three week, the wound show a 91% healing rate, and 96% after six week. The development of HITS-Bio represent a major measure toward make lab-turn tissue and variety_meat for checkup use. future attempt are concentrate on integration blood vessel into bio-print tissue, potentially expand its application to organ transplant and advance disease mold. This technique clasp promise for revolutionize regenerative medicine by enable fast, more effective tissue and organ fabrication.

However, information_technology difficult to achieve the Lapp cell density as what s found in the homo body with this standard approach. spheroid offer a promise option for tissue bioprinting because they rich_person a cell density similar to homo tissue. While three-D printing spheroid offer a feasible solution to produce the necessity density, research_worker have been express by the lack of scalable techniques.

exist bioprinting method often damage the delicate cellular structure during the printing procedure, killing some of the cell. Or the procedure are decelerate. In previously print research, Ozbolat and his colleague develop an aspiration-help bioprinting system. To address these issue, the team develop a new technique name High-throughput Integrated Tissue Fabrication System for Bioprinting ( HITS-Bio ). HITS-Bio use a digitally control nozzle array, an agreement of multiple nozzle that move in three dimensions.

We can then physique scalable structure very fast, Ozbolat state. information_technology 10-times fast than exist technique and keep More than 90% high cell viability. The team then show that the bioprinting technique can be use for on-demand tissue repair in a surgical setting in a rat model. The HITS-Bio technique offer an opportunity to make complex and functional tissue in a scalable manner.

Ozbolat state that the team is also working on technique to integrate blood vessel into the manufacture tissue, a necessity measure for produce More type of tissue that can be use clinically or for transplant. support from the National Institute of Biomedical Imaging and Bioengineering and the National Institute of Dental and Craniofacial Research support this work.
