Embryonic Stem Cells Go to Space!

A study performed on the NASA space shuttle Discovery showed that microgravity inhibits the regenerative potential of embryonic stem cells.

Since the discovery of stem cells, NASA researchers have been interested in how they are influenced by space travel. Exposure to microgravity often causes the breakdown of tissue and function, which poses serious challenges to the health of astronauts in space. Astronauts experience muscle atrophy, bone density loss, and slower heart rates in orbit. Affected tissues often rely on tissue-specific stem cells for regeneration and repair. Thus, studies examining the maintenance of tissue regenerative health during spaceflight are critical.

Stem cells may counteract the long-term side effects of radiation therapy in brain tumor patients

Radiotherapy is a widely used approach for the treatment of brain tumors. However, the benefits are often combined with serious irreversible brain damage that can have grave consequences on a cancer survivor’s life. Depletion of oligodendrocyte progenitors and demyelination are the main side effects, along with the impairment of motor coordination, all induced due to long-term use of radiation therapy. Myelin coating is generated by oligodendrocytes and required to protect and repair the brain neurons. Therefore, it is important to develop a novel treatment to rejuvenate the brain damaged caused by radiation therapy.

Ischemic stroke is characterized by acute loss of neurons, various glia and the disruption of synaptic architecture.  Here, we discuss the potential use of pluripotent stem cells to surpass the efficacy of current treatments.
