Southwest Research Institute (SwRI) has demonstrated a new application for its cell-expansion bioreactor to advance tissue engineering and cell-based therapies for treatment of injuries and diseases.

SwRI scientists used the bioreactor to replicate induced Pluripotent Stem Cells (iPSCs) derived from adult skin, blood, and other somatic cells. Their pluripotent state allows iPSCs to differentiate into any other cell type in the body, much like embryonic stem cells but without the same ethical ambiguity. Large quantities of iPSCs are needed for regenerative medicine and individualized health care, but current technology requires manual production.

“Using the SwRI-developed single-use 3D-printed bioreactor, we successfully harvested significant quantities of iPSCs,” said Senior Research Scientist Dr. Nick Mc Mahon, the leader on the project.

“We are working on further differentiating those iPSCs into neural progenitor cells, which could support the regeneration of neurons that are damaged due to injury. International studies have shown that neural progenitor cells can repair the spinal cord when administered in the first 28 days following a spinal cord injury.”

SwRI’s 3D printed bioreactor matrix boasts a larger surface-to-volume ratio compared to traditional 2D cell culture devices such as flasks or dishes, and it can grow more cells using an automated perfusion method. Due to the exceptional geometry of SwRI’s bioreactor, cells maintain a monolayer without forming clusters during the cultivation process, minimizing the risk of spontaneous differentiation into the wrong type of cells.

“Since the discovery of iPSCs in the early 2000s, scientists have been exploring their potential to revolutionize medicine by using a patient’s own cells to repair or replace damaged tissues to avoid immune rejection. Unlike embryonic stem cells, iPSCs pose no ethical controversy, making them a promising and responsible path toward personalized medicine,” said Institute Engineer Dr. Jian Ling.

SwRI plans to further refine the prototype to advance automation and provide a simplified plug-and-play cell replication platform to accelerate the development of iPSC-based therapies.
