Stem-cells
set the stage for one of the most controversial topics in Biology. These cells
have the potential to become any cell in the human body, repair any tissue in
the human body, and can replicate themselves for an unlimited amount of times. Recently,
Nature journal critics stirred up
some tension between Davide Vannoni’s (an Italian researcher) work on a
stem-cell related treatment and the Italian government; the latter wishes to
conduct a clinical trial to test the treatment’s validity. Even though the Nature journal argues against the
Italian government conducting a clinical trial with Vannoni’s work, due to the
flawed nature of Vannoni’s findings, progress with discovering a revolutionary stem-cell-related
cure for diseases, like cancer, outweighs the trial’s financial expenses and
must be conducted.
Stem-cells
distinguish themselves from other cells in the body with their ability to replicate
themselves indefinitely, and can become any cell (“The Stem Cell Controversy”).
Under specific conditions, stem-cells can become the cells for a specific organ
and insert themselves into that organ, which heals the tissues in that organ
(“Frequently Asked Questions”). In certain parts of the body, like the stomach
and bone marrow, the stem-cells can divide freely, while in other organs, like
the heart and pancreas, the stem-cells can only divide under specific
conditions (“Frequently Asked Questions”).
Stem-cell
research monumentally influences developing new cures. The unique traits of
stem-cells, like their ability to develop from generalized cells to cells with
specialized functions, and their ability to divide without limit, make them a
possible cure for difficult-to-treat diseases, like heart disease and diabetes
(“Frequently Asked Questions”). Continued research furthers our understanding
of how organisms develop from cells at early stages, and how stem-cells can replace
damaged cells in adults.

Recently,
the Italian government announced plans to watch over a clinical trial about a controversial
stem-cell therapy method, which a Nature
journal article avidly speaks against (“Trial and Error”). The article explains,
because flaws exist within the data that researcher Davide Vannoni collected, the
clinical trial, which will essentially waste all the money it requires, should
not be carried out. (“Trial and Error”). The trial will cost roughly €3-million,
or $3.9-million USD (“Trial and Error”).
In
a clinical trial, participants receive experimental variables according to the
research procedure (“Learn About Clinical Studies”). Experimental variables can
include medical drugs or procedures, and behavioral changes, such as one’s diet
(“Learn About Clinical Studies”). Clinical trials compare new medical
procedures with traditional ones, determining the most effective and efficient
products or treatment methods (“Learn About Clinical Studies”). The Italian
government’s stem-cell therapy clinical trial tests the validity of Vannoni’s
stem-cell treatment; if no compelling evidence supporting Vannoni’s method
emerges, his work will lose credibility.
The
Nature article asserts that this
trial should not be conducted. This article mentions how Vannoni’s research is
flawed, and even mentions how there is, “no good reason for [the trial] to be
carried out” (“Trial and Error”). Statements like that represent only a single
opinion; including it in an article takes away from the article’s credibility. The
article acknowledges the opposing side by mentioning how those favoring Vannoni
organized demonstrations with the patients’ families’ help, but the article fails
to expand on this topic or connect it with the other ideas the paragraph, creating
an impression that the author only included the statement for the sake of
including it, and fails to comprehend how much it impacts the topic.
Progressing through the article, the reader notices how the author only
discusses one standpoint until the last paragraph; opinionated language
appears, like when the author mentions the government taking a “pragmatic”
approach to the topic, unlike Vannoni’s methods, and even refers to Vannoni’s
practices as “scanty’ (“Trial and Error”). No matter how well the article hides
it, name-calling always detracts from someone’s standpoint through reducing a
reliance on facts when that person argues a point. This article’s opinionated tone
requires an examination for consistency and validity among the facts presented.
After
review, the data Vannoni bases his stem-cell procedure (known as Stamina
therapy) on is flawed, and the Nature
article establishes its argument upon this idea. The Stamina therapy procedure
involves removing patients’ cells from their bone marrow and manipulating those
cells in vitro (in a laboratory).
Ideally, this should make the bone-cells into nerve-cells (“Abbott”). The Nature article mentions how Vannoni
fails to provide adequate details regarding his procedures, and consistently
refers to his patent (“Trial and Error”). Another source mentions this and
explains an error with a picture on Vannoni’s patent (“Abbott”). The picture of
a nerve cell Vannoni uses on his patent bears a
striking
resemblance with a picture of a nerve cell used by another researcher named
Elena
Schegelskaya,
showing the inconsistency of Vannoni’s position (“Abbott”).
Schegelskaya based her publication, with that photo, around turning bone-cells
into nerve-cells, like Vannoni’s position, but both researchers used very
different procedures (“Abbott”).
The Nature article references this
inconsistency, and while Vannoni’s findings are flawed, this does not imply
that utilizing stem-cells from bone marrow is impossible, or that nothing will
be learned if the government carries out the clinical trial.
Next,
the Nature article discusses
Vannoni’s relation with Good Manufacturing Practices (GMP). GMP encompasses
regulations that the U.S. Food and Drug Administration erected, including ones
regarding recordkeeping, personnel qualifications, and process validation (“What is GMP”). The Nature article warns
that, “The very unlikeliness of the Stamina story should have made the Italian
government extremely wary” (“Trial and Error”). Utilizing a retrospective
statement this way, which mainly states the author’s opinion, alerts the reader
about a possibly biased data presentation ahead. Even though the author of this
Nature article presents truthful
information, the author’s presentation style draws attention away from the
facts presented, and even weakens claims, shown in this paragraph about
Vannoni’s response to GMP. The paragraph explains how he prefers oversight-free
environments, provides no detail regarding his procedures when prompted by
authorities, asserts that the therapy can only function without GMP, and moves often
to escape his opponents (“Trial and Error”). While the reader might assume that
the author presents truthful information about Vannoni, this paragraph’s accusing
and one-sided tone, established by the poor opening sentence, invokes a
skeptical mindset within the reader, and makes the author’s claim, that the
Italian government should not conduct the clinical trial, less creditable. This
paragraph reminds the reader of Vannoni’s flawed research, though, and reinforces
the author’s position.

Vannoni’s
Stamina therapy may be based on flawed data, but the Nature article poorly explains why the Italian government shouldn’t
look further into a topic like Stamina therapy by conducting a clinical trial. The
author acknowledges the incredible potential that stem-cells possess, but
falters when stating that a trial that could challenge some topics regarding
stem-cells will hinder progress within that field (“Trial and Error”). Even if conducting
further research on Stamina therapy yields no breakthroughs, new information
about stem-cells can still be learned. If Vannoni’s Stamina therapy falls flat,
we could wonder, “what made it not work in those conditions?”, even if the
therapy stemmed from false data. Avoiding a potential conflict between a
clinical trial and stem-cell research won’t benefit anyone. The trial demands a
hefty amount of funds, but the finances are well worth getting closer to
finding a cure that can save and improve millions of lives.
Stem-cells
greatly impact the medical world as we continue to learn more about them. Bone
marrow-based stem-cell procedures, similar to Vannoni’s Stamina therapy, currently
aid cancer treatment (“Bone Marrow Transplantation”). Inside the bone marrow
(sponge-like material inside bones), hematopoietic stem-cells can be found (“BoneMarrow Transplantation”). These stem-cells divide to produce more
blood-producing stem-cells, and are used with peripheral blood cells (cells
found in the bloodstream) in bone marrow transplant operations, called Bone
Marrow Transplantation (BMT) and Peripheral Blood Stem Cell Transplantation
(PBSCT) (“Bone Marrow Transplantation”). These procedures allow patients to
receive high levels of chemotherapy and radiation therapy by replacing
destroyed stem-cells in the bone marrow during these processes (“Bone Marrow
Transplantation”). This is just one revolutionary way that stem-cell treatments
have helped people overcome diseases, and the more familiar we are with
stem-cells, the more uses we’ll find for them.

The
Italian government should conduct the clinical trial for Stamina therapy, even
though Vannoni constructed the Stamina therapy method using false data. The Nature journal argues against conducting
the trial, citing Vannoni’s flawed data and the financial aspect of the trial
as reasons why, but suffers from a highly opinionated presentation style, costing
the article some credibility for its claims. The information we could obtain
from the trial, even if Stamina therapy doesn’t get us anywhere, goes towards
finding a cure for several, currently, un-curable diseases, and spending the
finances towards saving and improving the lives of millions of people is well
worth it.
