The field of genomics is incredibly interesting. For hundreds of years, we as a race have been
finding ways to react to disease, but here we have the possibility to
proactively prevent it by essentially changing our building blocks; our genetic
structure. While practical application
on that high a level isn’t in the near future, the fledgling science that is genomics
is catching on. There are already tests
that can be conducted via spinal tap that can determine if a fetus has Downs’
Syndrome or Turner’s Syndrome. Criminal
forensics has been using a DNA database to match criminals with DNA found at
the scene of a crime, and these matches are within 99.9%. In addition, the developments of cloned sheep
and cloned organs have shown us just how far-reaching this science is. There has been recent study done on
heart-attack patients in conjunction with stem-cell research. In a small group of 18 patients who had suffered
heart attacks; myocardial infarctions typically leave behind irreparable scar
tissue. Cells were drawn from the healthier
portions of the patients’ hearts and used to develop new tissue. This tissue was then implanted into the
scarred portions of the heart. In
patients who had this procedure was done, doctors observed a significant
improvement; over two years, nearly 70% of the scar tissue had regenerated. Patients who did not participate saw little
to no improvement. It’s crazy to think
that healthy tissue generated by your own body could help essentially rebuild
organs. My grandmother passed away due
to complications from cystic fibrosis, which is passed genetically. It also skips generations, so my cousins and
I are at a higher risk for it. It’s wild
to think that people with cystic fibrosis could eventually be able to regrow
lung tissue and live a healthy life.
