Guide | Harvard Team Develops a 'Vagina Chip' to Advance Bacterial Vaginosis Research
Scientists at Harvard University's Wyss Institute for Biologically Inspired Engineering have developed the world's first "Vagina Chip." The research provides a new platform for women's health studies and may support the development of new treatments.
Professor Don Ingber of the Wyss Institute said women's health has not received adequate attention and that the chip was created to address this gap. "Women's health issues have long been under-recognized, and we need more research to address them," he said.
Innovative technology: a Vagina Chip that models the vaginal microbiome
Organ-on-a-chip technology has advanced across many fields. These small devices culture living cells in channels on glass chips to mimic organ activity. Researchers have previously developed chips modeling the lungs, kidneys, bone marrow, and other organs; the Vagina Chip applies this technology to female reproductive health.
The work was initially funded by the Bill & Melinda Gates Foundation and grew from research on environmental enteric dysfunction, a childhood disease most common in low-resource countries and the second leading cause of death in children under 5. Studying this condition showed Professor Ingber the importance of the microbiome and inspired the Vagina Chip.
The chip was designed to study imbalance in the vaginal microbiome known as bacterial vaginosis. About one-quarter of women worldwide have bacterial vaginosis, which is associated with preterm birth, HIV, persistent HPV infection, cervical cancer, and other health problems.
Addressing a research gap in women's health
Bacterial vaginosis treatment has changed little since 1982 and relies mainly on two antibiotics. Development of new therapies has been slow because suitable animal models are lacking. Vaginal microbiomes differ greatly between species, making effective testing in other animals difficult.
Professor Ingber said the chip creates new research opportunities and may help identify treatments more quickly. It could greatly advance understanding of the vagina, cervix, and female reproductive system, particularly bacterial vaginosis, vaginal candidiasis, chlamydia, and endometriosis.
Broader prospects for women's health research
Scientists also hope to use the chip to study other conditions. Dr. Caroline Mitchell, an obstetrician-gynecologist at Massachusetts General Hospital, said: "Female reproductive health has long been neglected, and research has progressed slowly for many common conditions affecting women, such as vaginal candidiasis and endometriosis."
The chip is already being used to study how bacterial vaginosis affects sperm migration. Scientists are also combining it with a Cervix Chip to study transmission mechanisms of viral infections such as HPV and various bacterial diseases.
Researchers plan to add vascular cells and female hormones to model the menstrual cycle and the effects of hormonal changes on reproductive health.
Outlook: increasing attention to women's health
As the technology improves, researchers believe it will become an important tool for women's health research. By deepening understanding of female reproductive biology, it may help identify treatments and attract more global resources to the field.
Professor Ingber hopes the chip will accelerate treatment development and ultimately improve women's health worldwide. He said: "We must use innovative technology to better understand the female reproductive system and provide a scientific basis for future treatments."
