Stem cells may give a respite to COVID-19 infected

It's tough to approach ICMR with novel
such ideas: research outfit Advancells
While stem cell treatment is not a technique to eradicate or fix
coronavirus completely, there is proof to help the idea that infected patients,
under the treatment, might be more receptive to survive the disease.
That's because, stem cells oppose viral infection due to the presence of
specific qualities known as interferon gamma invigorated qualities (ISGs).
These are present in stem cells before their separation process happens. Thus,
stem cells can be expected to survive even if they are transferred into a
patient with confirmed infection of coronavirus, as per Vipul Jain, CEO,
Advancells, a research firm focusing on therapeutic applications of
regenerative medicine.
Mr Jain said, âEven medical science has determined how influenza virus
A/H5N1, with a history of causing intense lung injury, was destroyed by human
mesenchymal stromal cells (MSCs) in a mouse. Going back to basics has only
expanded the chances of positive outcome.''
Mesenchymal stromal cells (MSCs) are those stem cells which can separate
into an assortment of cell types. There are several other properties of MSCs
which make them suitable for clinical trials, such as they have ability to
reduce inflammation thus regulating the immune system back to healthy and an
extraordinary capacity to find the damaged tissues in human body. They can even
speed up the recovery of those damaged tissues.
For instance, to achieve desired outcome, specialists have used enormous
quantities of MSCs with one patient in Baoshan (Yunnan) who got 3 implantations
of 50 million umbilical blood cord derived MSCs, while every Beijing patients
got 1 mixture of 1 million cells for every kilogram of weight.
According to Advancells observations, MSCs can be acquired from fat, which
implies that everybody can use his/her cells, abolishing any contamination or
fatalities. In any case, extending them to the amount required for
implantation, takes 2 to 3 weeks which is why it is valuable to cryo-conserve (process
of preserving cells prone to damage) an individual reservoir of MSCs, that
would permit to get to an early and progressively beneficial treatment.
It may be noted that, some 14 trials have been conducted using stem cells
to treat coronavirus patients in China. They recommended stem cells may be the
option to fix the extreme organ damage brought about by the virus.
âMSCs can lessen the overproduction of immunity cells caused as a response
to the virus and lower down the levels of inflammatory substances. Thus,
bringing the weak framework and the whole body back to its ordinary state,''
Mr. Jain said.
What can be securely said at this stage following this spearheading study,
as per Advancells, is that MSCs demonstrate extraordinary potential to turn into
an important part of eradicating something so huge coronavirus itself.
Commenting on India scenario, he further said, âSadly, India is slow in
terms of awareness, also it is tough to convince ICMR with innovative ideas.
China had used it and all patients who have gone for stem cell therapy were
recovered. Israel just announced they would start a stem cell pilot for
treating coronavirus.â
