Episode 025: Henrietta Lacks vs. HeLa, and the People Behind the Specimens

The efficacy of any biomedical researcher is based on his or her foundation of scientific knowledge.  Few would have any problem grasping that idea.  What's less well understood, by both researchers and laypeople alike, are the stories of the biological materials they work with.  Often these materials are cell cultures, tissue samples, human DNA.

Unlike the chemicals, reagents, test tubes, and machinery used in research, these materials often come from people.  That's easily forgotten when they can be ordered from catalogs and websites in the way of other commodities. But those people, who may no longer live among us, have stories.  In the case of Henrietta Lacks, an African American woman who passed away in the early 1950s of cervical cancer, the cells taken from her without her or her families' knowledge touched off a revolution in biomedical science. 
Henrietta and Day Lacks (From
"The Immortal Life of Henrietta Lacks,"
R. Skloot, 2009)
They've contributed to the vaccine for polio, were the first cells to be cloned, and have been used in a number of cancer, virus, and pharmacological studies all over the world. Rebecca Skloot's 2009 book "The Immortal Life of Henrietta Lacks" noted that Mrs. Lacks' cells have been used in more than 60,000 studies, and 300 more are being added each month.  They are of huge importance to science because they were the first so-called immortal cell line--unlike most cells, they divide and reproduce essentially without limit.  But though no-one in Henrietta Lacks' family knew of their existence at first, the cells ultimately became of huge importance to her descendants.  In this episode, Alison Pletch, Eboni Jones, Greg Pelc, and I were honored to be able to welcome two members of the Lacks family to the show.  David Lacks is Mrs. Lacks' grandson, and Victoria Baptiste is her great granddaughter, and they spoke with us about their ancestor, informed consent, and their work with the National Institutes of Health on HeLa cell research guidelines.

Episode 024: John Lawrence, Doctors Without Borders, and Syria

Syria is in the midst of a civil war.  As a measure of the seriousness of the situation, a Reuters report out recently says that the war has claimed the lives of 115,000 people.  And with 5000 of those deaths in September alone, it seems as though international pressure to eliminate Syria's chemical weapons hasn't slowed the war down at all.  The UN reports that only twelve international aid organizations are approved by Syrian officials to work in country. One of those is Doctors Without Borders, or Medecins Sans Frontieres.  This time on The Short Coat Podcast, we welcome back Dr. John Lawrence, pediatric surgeon and associate professor of Surgery at the University of Vermont College of Medicine. and formerly of the University of Iowa Carver College of Medicine.  Dr. Lawrence has performed six surgical missions working with MSF, and he's come to Iowa to talk about Syria, from which he's recently returned.  Not long ago, medical students Jessica Gaulter, Katherine Ryken, and Ethan Forsgren sat down to talk with him about his experiences with MSF and in Syria.

Local coverage: Opportunities for third year students in Des Moines

This episode introduces students to the Des Moines Area Medical Education Consortium's group of hospitals,  and the unique opportunities available to third-year students at the Carver College of Medicine who can take advantage of a year-long rotation in Iowa's capital city.  Dr. Steven Craig, the executive director of the DM Consortium, talks with Natalie Ramirez about what the benefits and opportunities exist for M3s in our state's capital city.
