BioLife4D, a bio-based 3D printing technology startup, recently announced that it has successfully produced human tissue in the form of a heart patch, which brings it closer to the printable organs that can be used for transplantation.
Dr. Joseph Woo, director of the Department of Cardiothoracic Surgery at Stanford University, told Xiaobian, "Interestingly, it was printed in 3D . Instead of making it into a plate by hand, you can do 3D printing on the plate."
BioLife4D says bio-printed heart patches can save a lot of cost and time by adding creative processes. The company has raised more than $1 million to sell public securities, aiming to eventually provide organs on demand.
According to the Centers for Disease Control and Prevention, about 610,000 people die of heart disease each year and 735,000 suffer from heart disease. According to a report by the non-profit organization Global Financial Integrity, in the developing world, the black market for organ trafficking generates between 840 million and 1.7 billion dollars a year.
Heart patch
Woo explained that the idea of ​​a heart patch is similar to a patch on a tire.
“This is a colloquial term used to describe a tissue engineered structure placed on the heart to repair the heart. The patch can be made up of a variety of things, such as aggregates of stem cells, or gels. , where protein can help heal the heart."
According to BioLife 4D, heart patches created at Houston's research institutes are derived from the patient's white blood cells and contain multiple cell types in the human heart.
Woo, a spokesperson for the American Heart Association, pointed out that this development can bring material benefits to the industry by reducing the time it takes to make patches, increasing accuracy and increasing stability.
“The ability to change things very quickly. You just need to change the ink and rewrite the program,†Woo said. “And cost – it's labor intensive. When you switch from manual production to machine manufacturing, the capital expenditure and labor costs of the machine are reduced.â€
