The members of the Myers lab have been on the move this year, attending conferences and working with collaborators. We’re so happy to see everyone in-person!

Congratulations to Myers Lab member Shuyang Fang for placing first in the SB3C 2021 ASME-BED Student Paper Competition (PhD level, Soft Tissue Biomechanics section). Great job Shuyang!

What is the mechanical role of small leucine-rich proteoglycans (SLRPs) in the mouse cervix? In collaboration with the Mahendroo lab at the University of Texas Southwestern Medical Center, we use mechanical testing and computational modeling to reveal decorin and biglycan’s impact on time-dependent and equilibrium properties of the nonpregnant and pregnant cervix.

Mechanical Response of Mouse Cervices Lacking Decorin and Biglycan During Pregnancy

What is the role of small leucine-rich proteoglycans (SLRPs) in cervical remodeling during pregnancy? In collaboration with the Mahendroo lab at the University of Texas Southwestern Medical Center, the combination of imaging, immunohistochemistry, collagen crosslink analysis, and mechanical testing reveals an important regulatory role of SLRPs in the uterine cervix.

This article is written by Mariano Colon-Caraballo (from collaborator Mala Mahendroo’s lab), co-authored by Nicole Lee.

Novel regulatory roles of small leucine-rich proteoglycans in remodeling of the uterine cervix in pregnancy

We loved having Jada Hinds, a 2021 SURE Fellow from Duke University, as an undergraduate researcher in our lab over the summer! You can watch her present her work on studying the effects of maternal anatomy parameters on cervical loading at the Columbia SURE website.

The Myers Lab congratulates Lei Shi on his well-deserved doctoral degree from Columbia University! Lei’s work mechanically testing and modeling the human cervix not only characterizes the equilibrium response of human cervical tissue, but also pioneers capturing its time-dependent mechanical response.

Congratulations to Myers Lab members Nicole Lee and Arielle Feder for placing in the SB3C 2021 ASME-BED Student Paper Competition! Nicole Lee tied for first place at the PhD level in the Soft Tissue Biomechanics section, and Arielle Feder got runner-up at the BS level in the Soft Tissues section. We couldn’t be more proud!

How do mechanical properties of the human uterus change throughout pregnancy, and how do they differ across uterine anatomical locations? We combine video extensometry, mechanical testing and computational modeling to explore in our recently published manuscript.

Our new manuscript reports measurements from 2D ultrasound of uterine and cervical growth during pregnancy and a design table driven method to build patient-specific models.

The article is authored by Erin Louwagie in collaboration with Helen Feltovich at Intermountain Medicine/UoU and Timothy Hall at UW-Madison.

We are so proud of our undergraduate and masters level students, who recently wrapped up their summer research projects! Their final presentations were recorded and we are so excited to share!

Tara Atkinson

Tara is currently a masters student in Mechanical Engineering. Her project this summer focused on developing a parametric model of monkey uteri.

Anabella Advincula

Anabella is an incoming freshman student at Barnard College. She led a team in the Columbia University Summer Design Challenge to reimagine prenatal care for better telemedicine visits. Other members of the team were Tara Atkinson, Arielle Feder, and Imani Phillips.

Lizzie Ayton

Lizzie is an undergraduate student in Mechanical Engineering who joined the Myers lab this summer to work on finite element modeling of the rodent reproductive tract. She focused on building a parametric model of the mouse uterus and cervix.

Divya Rajasekharan & Arielle Feder

Divya and Arielle are undergraduate students in Mechanical Engineering who worked jointly this summer to build parametric patient-specific models of the uterus and cervix for late gestation. They also worked on modeling additional structures important for birthing simulations, the pelvic bone (Divya) and vaginal canal (Arielle). Their videos have been uploaded to Columbia Academic Commons, and can be found using the links below:
