Calvin College has received
its largest National Science Foundation grant ever to buy a piece of
equipment rarely seen on undergraduate campuses.
The school was given $224,934
by the NSF to purchase a flow cytometer, a specialized instrument usually
found in hospitals, research labs and large, graduate-level universities.
In fact, in Grand Rapids there are currently flow cytometers at just
three locations, including Spectrum Hospital, the VanAndel Rsearch Institute
and the Grand Rapids Blood Bank.
Calvin has just installed
its BD Biosciences FACSCalibur flow cytometer in its John "Doc"
DeVries Hall of Science - right in time for the start of classes on
September 8.
Professors are excited about
the possibilities of the flow cytometer for their own research and for
its applications to undergraduate science courses at Calvin.
Says Calvin biology
professor David DeHeer (above): "The flow cytometer will significantly
enrich the research training of undergraduate students, benefiting in
particular, upper-level students in cell and molecular biology. The
instrument will play a strategic role in preparing our students for
graduate education and laboratory research, a key step in equipping
young people to provide vital contributions to the scientific and engineering
communities."
A flow cytometer is a sophisticated
instrument for detecting and measuring specific molecules, including
DNA, in individual living cells. For example, researchers use the instrument
to identify malignant cells, cells that express specific genes and thereby
exhibit abnormal functions, or cells that cause specific diseases such
as leukemia. Not only can a flow cytometer analyze thousands of cells
each second, but it can also separate them into groups with specific
functions or discrete genetic markers. These populations then can be
cloned and further studied in the laboratory.
Calvin's new flow cytometer
is about as large as a household dishwasher, but, says DeHeer with a
smile: "considerably more expensive." And it's a complicated
piece of equipment. It won't work without a computer which is required
to collect and analyze the hundreds of thousands of measurements the
flow cytometer makes each second. Just to learn to use the flow cytometer
will require DeHeer and others in the Calvin biology department to each
complete a one-week training course.
DeHeer plans to
use the flow cytometer to explore ways to eliminate or quiet inflammatory
cells involved in the failure of artificial joints such as those of
the hip and knee. Biology professor John Ubels will examine gene expression
in lacrimal gland cells, cells whose normal function helps to prevent
dry eye disease. Arlene Hoogewerf will seek to identify processes by
which certain bacteria are able to evade an organism’s defense
mechanisms and cause infection. Stephen Matheson will examine the ability
of certain molecules to stimulate nerve cell growth and maturation,
processes that could enable injured nerve cells to heal or reproduce.
And Elizabeth Howell will identify factors that direct a cell to copy
its DNA or to repair damaged DNA.
