For as long as humans have documented life, there has been
“research.” Research is the foundation of science and as we continue to learn
more, we continue to optimize our research methods. In 2010, the National
Institute of Health (NIH) started funding on what could go down in history as
one of the greatest scientific advancements of our generation, the tissue chip.
In our current model of research there are very strict regulations and
guidelines on how research must be conducted. While these regulations are very
important considering our horrifying history of human research may end up
costing billions of dollars and years of research while patients continue to
suffer (Skardal et al. 2017).
With the
discovery of the tissue chip, we may now be able to conduct clinical research
on human models without the risk of harming the patients (NIH.gov). Potential
drugs are tested on human cells in a 2D model, meaning that they are cells that
are plated in vitro. While this is a very important aspect of research it fails
to imitate the microenvironment and tissue to tissue interactions (Skardal et
al. 2017). The next phase of drug development is the animal model, and while it
is suitable for learning the systematic effects, there are many drugs that have
different effects on rats compared to humans. If everything passes the FDA’s
guidelines, then they will approve the drug for clinical trials (FDA.gov).
This technology is amazing and has many
applications from understanding drug toxicity/ addiction to learning the
effects that zero gravity over time has on our organs (NIH.gov). Even with all
of these incredible applications, it is important to discuss some of the ethical
implications of such technology. One big issue that some people are upset about
is in response to the idea that we can “grow a brain.” Currently, the NIH is only
concerned with discovering the drug interactions with the blood-brain barrier,
but theoretically, we can grow a brain and observe the neuronal interactions.
This brain activity would be derived from a donor and we don’t know the
implications at this time. Yes, you are right this technology is amazing, but
it is our role in the scientific community to ensure that we hold the
organizations using this technology are non-maleficent in their actions.
