They created the first 3D heart with human tissue

The milestone means in the survey because until now, only tissues without blood vessels had been created.

"A complete heart has been designed and successfully printed with cells, blood vessels, ventricles and chambers," confirmed the project leader, Professor Tal Dvir of the School of Molecular Medicine and Biotechnology's Tel Aviv University.

"These materials (cells and tissues of the patient) serve as biological bonds, substances based on sugars and proteins that can be used for 3D printing of complex tissue models"he explained.

In this sense, he stressed the importance of this heart for "the engineering of the replacement of tissues and custom organs in the future". For this work, the scientists carried out a biopsy of the adipose tissue of the patients,They evoke cellular tissue materials and reprogram cells for them to function as pluripotent stem cells, differentiating from cardiac cells..

Then they were mixed with a hydrogel that filled the ink function for printing, but also used cardiac patches compatible with the immune system, specific to this patient, with blood vessels. The result was full heart which at this stage is about the size of a rabbit organ.
