Using stem cells to 3D-Print heart tissue is an exciting development in regenerative medicine. The research was conducted by a team of scientists at Stanford University and published in Nature Communications in 2021.
The scientists used induced pluripotent stem cells (iPSCs) to create heart tissue that could be used to repair damaged heart tissue. iPSCs are a type of stem cell that can be generated from adult cells, such as skin cells, and reprogrammed into a pluripotent state, meaning they can develop into any cell in the body.
The researchers created a bio-ink of the iPSCs and a supporting matrix, which they then used to 3D-Print heart tissue with a complex microarchitecture that closely mimics the structure of actual heart tissue. By using 3D Printing to create personalized heart tissue from a patient’s stem cells, it could be possible to replace damaged heart tissue with healthy, functional tissue.
