The Arroyo Lab: Bridging Metabolic Research and Maternal Wellness

After navigating the emotional challenges of infertility and pregnancy complications alongside his wife, Dr. Juan Arroyo, a professor in the BYU Department of Cell Biology and Physiology, transformed personal hardship into scientific purpose. Inspired by his personal journey, Arroyo’s lab investigates how trophoblast cells, which enable the vital exchange of nutrients and waste between mother and fetus, and mTOR proteins, which regulate cell growth and energy use, contribute to placental development and influence pregnancy outcomes.

By examining conditions like Intrauterine Growth Restriction, Preeclampsia, and preterm delivery, the Arroyo Lab works to uncover the biological mechanisms behind these complex pregnancy complications. The team also investigates how metabolic and respiratory factors, such as vaping and secondhand smoke, can disrupt fetal development. Through this research, Arroyo aims to raise awareness of these risks and develop strategies to improve the management of high-risk pregnancies.

Students in the lab gain hands-on experience with molecular techniques, tissue culture, and in vitro/in vivo studies. Encouraged to contribute to publications, they develop valuable academic and professional skills. Arroyo values the lab’s close-knit environment and draws inspiration from his students’ passion and growth. “The involvement of the student is in every single step of our laboratory,” Arroyo says. Elizabeth Thurmond (MMBIO '26) joined the lab for its focus on pregnancy and maternal health complications. Along with gaining valuable technical skills, she appreciates the collaborative environment in the lab. “Each project truly is a team effort,” she expresses. “It’s fun to see all of the pieces come together.”

Benjamin Davidson (BIO '27) joined the lab after working as a TA for Arroyo. Now a member of the animal care team, he works with mouse models to study pregnancy-related diseases like gestational diabetes and preeclampsia. “The lab has strengthened my ability to think about scientific research and helped me grow as a person,” he shares. The experience has boosted his confidence as a pre-med student, and he encourages future lab students to stay motivated, disciplined, and creative.

Arroyo believes faith and science go hand in hand, especially in his lab. “Pregnancy is a miracle. Everything has to be so perfect,” he explains. As he encourages students to recognize the hand of Heavenly Father in their work, Arroyo finds his own faith strengthened. “I’ve seen their faith and their dedication. Their testimony changes mine every day.”

Students in the lab feel deeply impacted by the integration of faith and science. Davidson shares that each lab meeting begins with a prayer, inviting the Spirit and helping them focus on what matters. “Our professors always emphasize God’s role as the creator of life and His providence in making all of its intricacies and complexities,” he explains. Thurmond adds that even the smallest details testify of divine design: “These little cells grow so effortlessly in the perfect ratio to make every one of us. To me, that is evidence of my loving Heavenly Father’s existence.”

The Arroyo lab is an environment for students to gain hands-on experience, learn valuable collaboration skills, and continue on their journeys toward a successful and service-oriented future. This lab is for students with a positive attitude who are driven and willing to learn. To get involved, students should email Dr. Juan Arroyo.
