欧美口爆视频 Boulder leading effort with 欧美口爆视频 Anschutz, Mayo Clinic to use microgravity to grow stem cells

The University of 欧美口爆视频 Boulder is leading a to advance stem cell research in low Earth orbit.

NASA has awarded the university鈥檚 BioServe Space Technologies a three-year grant to study the use of microgravity to grow hematopoietic stem cells (HSCs). The cells, which will come from umbilical cord blood or bone marrow, show potential to treat serious medical conditions including blood cancers that require bone marrow transplants, fatal blood disorders, severe immune diseases, and certain autoimmune diseases, such as rheumatoid arthritis.

鈥淭he field of bio-regenerative medicine is rapidly expanding, and there is enormous potential to treat a broad set of diseases and organ failure,鈥� said Louis Stodieck, BioServe鈥檚 chief scientist and a research professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences. 鈥淢icrogravity offers us the opportunity to try to mimic the human body in a way you can鈥檛 in a cell culture dish or bioreactor here on Earth.鈥�

Collaborating with BioServe on the research are at the 欧美口爆视频 Anschutz Medical Campus, Mayo Clinic, and , a company that grew out of research at 欧美口爆视频 Anschutz.

鈥淪uccessful expansion could grow the cord blood resource pool as well as transplant potential,鈥� said Louise Helander, medical director of ClinImmune. 鈥淭he possibility of improving precursor HSC expansion of gene-edited cells could be the gateway to expanding bioregenerative medicine options for multiple medical conditions and will help expand access to the growing interest of providing personalized medicine in the form of HSC treatments.鈥�

The work will include development of a bioreactor that can grow stem cells in space more effectively and efficiently than can be done in ground labs. Once grown, the cells would be cryogenically frozen and brought back to Earth as medical treatments. It is cutting-edge research with major possibilities.

鈥淚 won鈥檛 say there is anything simple about this, doing it in space, but expanding these cells on the ground they are subject to a lot of shear stresses in stir tanks that can cause damage or induce them to differentiate and turn into something that鈥檚 not useful,鈥� Stodieck said. 鈥淚n microgravity, we can grow them in an environment that鈥檚 similar to your body, where they can stay suspended and essentially mimic the environment in your bone marrow.鈥�

BioServe has decades of experience with life science research in orbit, and currently has several similar cell culture systems on the International Space Station for other analyses.

While conducting research in space is expensive, companies like SpaceX have made major advancements in cutting costs for rocket launches, and NASA believes there is additional potential for cost reductions, making biomedical research more financially viable.

鈥淭his has to be cost competitive with ground treatment or demonstrate a significant medical advantage,鈥� Stodieck said. 鈥淎s we get further into the work, NASA also expects us to have outside investors to make the process viable. NASA鈥檚 whole premise is to create commercial opportunities in orbit using the space station, which will drive costs down.鈥�

If the team is successful, the technology will enable cell therapy transplantation, especially in children and younger adults, where long-term bone marrow cell repopulation is critical to lifetime health.

鈥淭here are a lot of questions to answer, but that鈥檚 why we do research,鈥� Stodieck said. 鈥淚n addition, much of the technology we develop for this could also apply terrestrially. We could improve bioreactors more broadly to expand stem cell research and medical treatments in space and here on Earth. I鈥檓 very excited.鈥�

The first 20 star-trekking mice to travel to the International Space Station, riding aboard a spacecraft built by Hawthorne-based Space X, have returned to their home lab at UCLA.

But the mission isn鈥檛 over for the mice, , according to a scientist participating in the project that aims to help humans battle bone loss.

For now, the pioneering rodents are awaiting their rodent counterparts, still orbiting 220 miles above Earth on the space station鈥檚 . And they鈥檙e getting reacquainted with life back on Earth, dealing with such challenges as normal gravity.

A SpaceX rocket was slated to launch two University of 欧美口爆视频 Boulder-built payloads to the International Space Station (ISS) from Florida on Thursday, including one to look at changes in cardiovascular stem cells in microgravity that may someday help combat heart disease on Earth.

The second payload will be used for rodent studies testing a novel treatment for bone loss in space, which has been documented in both astronauts and mice. The two payloads were developed by BioServe Space Technologies, a research center within the ,

Several students are playing significant roles in the upcoming launch of a SpaceX rocket carrying two 欧美口爆视频 Boulder payloads 鈥� one designed to help researchers better understand and perhaps outsmart dangerous infections like MRSA, another to help increase the proliferation of stem cells in space, a potential boon for biomedical therapy on Earth.

Shelby Bottoms and Ben Lewis, both master鈥檚 students in the , are in Florida for the upcoming launch of the SpaceX rocket carrying the 欧美口爆视频 Boulder-built payloads. Both are helping to assemble flight hardware designed and built by 欧美口爆视频 Boulder鈥檚 for the launch Feb. 18 to the .
