The recent renaming of the Center for Perinatal Biology at Loma Linda University School of Medicine (LLUSM) has drawn attention once again to the incomparable legacy of the late Lawrence D. Longo, MD.
As announced in the June 22 edition of The School of Medicine Report, the center has been renamed the Lawrence D. Longo MD Center for Perinatal Biology because of Longo’s world-renowned leadership in the fields of developmental biology and physiology, maternal-fetal medicine, and obstetrics/gynecology. The new name helps assure that Longo’s passion for issues relating to women’s health and fetal development will continue to be the focus of the center.
According to William J. Pearce, PhD, professor of physiology at Loma Linda University (LLU) and long-term Longo collaborator, researchers at the center “actually moved the field during the past three decades. What we did was to incorporate novel ideas and technology in order to open up new areas of investigation.”
Pearce should know. After completing three years of postdoctoral training at UCLA in physiology and pharmacology, he was recruited as director of research at White Memorial Medical Center in 1982, where he worked under the late George Kypridakis, MD, pathologist and LLU associate dean. Kypridakis worked with Longo to arrange an assistant professorship for Pearce at Loma Linda in 1983.
Five years later, after Pearce was awarded his first R01 grant, Longo asked him to join the center faculty full-time. Pearce accepted the invitation and worked alongside his colleague and mentor for the next 33 years until Longo’s death in January 2016.
Pearce recalls that Longo insisted on the highest academic standards, and sometimes even made things more challenging for his junior faculty by competing with them on collaborative projects. The strategy paid off, Pearce notes, by spurring team members to greater accomplishments. “We were all super productive,” he says.
At the conclusion of the momentous symposium held to celebrate the 40th anniversary of the center in 2013, Pearce was asked to contribute a chapter to a 2014 book commemorating the event. Titled Advances in Fetal and Neonatal Physiology, the 240-page volume was published by Springer and edited by Lubo Zhang, PhD, and Charles A. Ducsay, PhD. Zhang succeeded Longo as director of the center, and Ducsay is a professor of physiology at LLUSM. The book is available at the Del E. Webb Memorial Library on the LLU campus.
Pearce’s chapter, “The Fetal Cerebral Circulation: Three Decades of Exploration by the LLU Center for Perinatal Biology,” deals with one of the center’s key research interests. It may be accessed online at http://www.ncbi.nlm.nih.gov/pubmed.
In the overview of his chapter, Pearce notes that, “The past three decades have transformed thinking about, and understanding of, the fetal cerebral circulation. Overall, it is clear that fetal cerebral arteries are in many ways structurally and functionally quite different than adult cerebral arteries.
“More importantly,” he continues, “the mechanisms that govern the composition and contractility of cerebral arteries are highly dynamic and involve multiple mechanisms operating at all levels of organization.”
Pearce goes into greater depth in explaining the specifics involved before summarizing the accomplishments of the center in general terms.
“As for most scientific programs of research, studies of the vascular biology of the fetal brain have produced more questions than answers,” he continues. “That said, it is clearly a worthy topic of continued investigation, particularly as recent work suggests that smooth muscle plays a critical role not only in regulating blood flow, but in the responses to, and recovery from, cerebral injury.
“Without doubt,” he concludes, “the Center for Perinatal Biology will continue their adventures in this arena, and with all the new genetic and analytical tools becoming available, the next 30 years might be even more interesting than the last.”
When he’s not in the laboratory or teaching classes, Pearce enjoys playing the bass guitar and other instruments, recording his own rock and jazz compositions in his home studio, cooking for family and friends, building speaker cabinets and amplifiers, and writing stories with his wife, a professional author of more than 200 children’s books.
Most of all, however, he loves science and research. “Nothing’s more fun than that!”
