Human Muscle Grown Cells Shot to Space To Investigate Ageing in Microgravity Condition

The University of Liverpool recently conducted a study to investigate the reduction of muscle mass through revealing portions of human muscle cells into microgravity conditions while on the international space station (ISS).

The study authors also tried to investigate any aging effects associated with it. Then, finally, the University launched its latest project on a rocket heading to the International Space Station. The project, known as MicroAge, arrived at the station where scientists conducted experiments on its contents.

The scientists experimented with microgravity’s conditions contribution to reducing human muscle mass. Several studies had previously revealed that while on assignments, astronauts encounter a higher rate of muscle mass due to their long durations in space.

How the researchers conducted the study

One of the study authors, Professor Anne McArdle, stated that the team’s investigations on the mechanisms accountable for the muscle mass loss had begun a few years ago.

McArdle revealed that the study focused on identifying means to significantly reduce the health conditions in aging people and astronauts. The study also plans to identify the causes and preventions of muscle loss to aid both astronauts and the elderly.

The University’s funds for the research were donated by the U.K. Space Agency, who donated £1.1 million at the beginning of the research. The scientists cultivated and harvested “mini muscles” from human cells. The cells were then kept in 24 containers and sent to space.

A few of the targeted cells were electrocuted to imitate a human who exercised and kept fit. At the same time, the rest were given high levels of protective heat shock proteins that prevented any aging muscles from deteriorating.

Similar studies conducted by NASA 

The space station recently revealed that it conducted various studies to improve the aging conditions of astronauts. However, none of the researchers arrived at a substantial conclusion.

NASA conducted a study where they focused on the growth of an astronaut and his twin. Scott Kelly resided in a floating laboratory while scientists monitored his twin on earth.

The findings revealed that Kelly’s telomeres grew longer in the duration of his stay however began shrinking once he returned.
