Stem cell therapies capable of regenerating any human tissue damaged by injury, disease or ageing could be available within a few years, following landmark research led by UNSW Australia researchers.
The repair system, similar to the method used by salamanders to regenerate limbs, could be used to repair everything from spinal discs to bone fractures, and has the potential to transform current treatment approaches to regenerative medicine…
Study lead author, haematologist and UNSW Associate Professor John Pimanda, said the new technique, which reprograms bone and fat cells into induced multipotent stem cells (iMS), has been successfully demonstrated in mice…
“We are currently assessing whether adult human fat cells reprogrammed into iMS cells can safely repair damaged tissue in mice, with human trials expected to begin in late 2017.”
There are different types of stem cells including embryonic stem (ES) cells, which during embryonic development generate every type of cell in the human body, and adult stem cells, which are tissue-specific. There are no adult stem cells that regenerate multiple tissue types.
“This technique is ground-breaking because iMS cells regenerate multiple tissue types,” Associate Professor Pimanda said.
“We have taken bone and fat cells, switched off their memory and converted them into stem cells so they can repair different cell types once they are put back inside the body…”…
The study’s first author, Dr Vashe Chandrakanthan, who developed the technology, said the new technique is an advance on other stem cell therapies being investigated, which have a number of deficiencies.
“Embryonic stem cells cannot be used to treat damaged tissues because of their tumour forming capacity. The other problem when generating stem cells is the requirement to use viruses to transform cells into stem cells, which is clinically unacceptable,” Dr Chandrakanthan said.
“We believe we’ve overcome these issues with this new technique.”
RTFA for the basic explanation of what the good doctors have accomplished. Bare bones, so far. Interesting that the lead in human trials is considering back and neck pain, spinal disc injury, joint and muscle degeneration. Those bits and pieces which bring major debilitation to life and lifestyle under failure.
Though, whatever we can put back together again – will help.
