Stanley M. Gartler, Molecular Biologist, Passes Away at 102

Stanley M. Gartler, a notable molecular biologist and geneticist, known for his groundbreaking work in demonstrating that cancerous tumors arise from a single mutated cell, passed away on May 25 at his Seattle home, aged 102. His death, which didn’t garner much media attention initially, was later confirmed by his nephew, Dr. Richard Weiner.

Beginning his exploration of cancer’s genetic roots in the early ’60s, Dr. Gartler joined the University of Washington’s genetics department in 1957, running an active lab until 2007. At the dawn of the 20th century, Theodor Boveri, a German zoologist, had speculated that tumors originate from a single cell that proliferates uncontrollably, but he couldn’t substantiate his hypothesis.

Collaborating with pathologist David Linder, Dr. Gartler conducted research on benign uterine tumors—those fibroid tumors removed during hysterectomies, particularly in Black women. Generally, females carry two X chromosomes, while males have one X and one Y. Due to a random occurrence called X inactivation, most genes in one of the X chromosomes of women are silenced early in development. Dr. Gartler discerned that the silencing of the G6PD gene on the X chromosome was pivotal in understanding a cell’s development.

In a 1965 publication in the journal Science, he and Dr. Linder revealed that normal uterine tissue displayed a mix of gene variants—A and B—in roughly equal proportions. However, in tumor samples, only one variant appeared, indicating that tumors arise from a single cell.

“To treat cancer effectively, we must comprehend its biology,” stated Dr. Gail Jarvik, a leader in medical genetics at the University of Washington. “Current chemotherapies and targeted therapies hinge on the understanding that mutations drive the disease.”

That same year, while examining genetic markers in human cells, Dr. Gartler discovered permanent human cell lines—cultured cells that are easily reproduced and essential for disease research and drug development.

His findings, however, revealed an astonishing truth. In 18 supposedly independent cultures, the genetic markers were all the same, showing the rare A variant of the G6PD gene, almost exclusively found in Black individuals. It soon became apparent that these claimed unique cultures were actually contaminated by the first permanent human cell line—known as the HeLa line—established in 1951 at Johns Hopkins Hospital.

The HeLa line, derived from Henrietta Lacks, a Black woman who died of cervical cancer, had its cells distributed for research without her or her family’s knowledge. These cells subsequently contributed significantly to advancements in vaccines, cancer research, and more. Unfortunately, Dr. Gartler noted that due to careless laboratory practices, HeLa cells could easily contaminate other cultures.

Many researchers, believing they were studying cells from other tissues, might have been unwittingly working with cervical cancer cells from the HeLa line. He later attributed the contamination issues to “sloppy techniques” in research settings.

During a 1966 conference in Pennsylvania focused on cell culture, Dr. Gartler presented his discoveries to an astonished audience of 700 scientists, suggesting their original cell lines were “open to serious question.” Rebecca Skloot chronicled this event in her 2010 book, “The Immortal Life of Henrietta Lacks.” Michael Gold, in his book “A Conspiracy of Cells,” acknowledged the substantial impact of Dr. Gartler’s revelations.

He “really raised the alarm” on a widespread issue that “wasted countless hours and millions of dollars” on flawed science, according to Gold. While many researchers were reluctant to accept this news, a significant number did come to terms with Dr. Gartler’s findings.

His work is credited with driving improvements in laboratory quality control and the authentication process for cell lines. The story of the HeLa line serves as a significant lesson in modern medicine, underscoring crucial ethical considerations regarding consent, privacy, and the rights of families concerning their relatives’ biological materials.

In a 2012 lecture, Dr. Gartler emphasized the importance of privacy in research—something lacking in Henrietta Lacks’ case. “I wouldn’t want to be remembered as just a cancer cell,” he remarked.

Born on June 9, 1923, in Los Angeles to Romanian immigrant parents, Dr. Gartler’s early life was shaped within a dry cleaning business run by his father. He initially pursued agriculture studies at UCLA before interrupting his education to serve in World War II as a radio operator in the Army Air Forces.

After the war, he returned to UCLA, completed his bachelor’s degree, and went on to earn a Ph.D. in genetics in 1952 from UC Berkeley, cultivating his interest in human genetics further during a postdoctoral fellowship at Columbia University. Eventually, he became the first faculty member in the newly established division of medical genetics at the University of Washington.

Dr. Gartler’s wife, Marion Mitchelson Gartler, who passed away in 2016, was a writer and editor. He is survived by no immediate family members. In 1962, he co-authored an influential paper about a girl with mixed XX and XY cells, revealing the complexities of sex determination.
