Kunisaki Lab
The Kunisaki lab is a NIH-funded regenerative medicine group within the Division of General Pediatric Surgery at Johns Hopkins that works at the interface of stem cells, mechanobiology, and materials science. We seek to understand how biomaterials and mechanical forces affect developing tissues relevant to pediatric surgical disorders. To accomplish these aims, we take a developmental biology approach using induced pluripotent stem cells and other progenitor cell populations to understand the cellular and molecular mechanisms by which fetal organs develop in disease.
Our lab projects can be broadly divided into three major areas: 1) fetal spinal cord regeneration 2) fetal lung development 3) esophageal regeneration
Lab members: Juan Biancotti, PhD (Instructor/lab manager); Annie Sescleifer, MD (postdoc surgical resident); Kyra Halbert-Elliott (med student), Ciaran Bubb (undergrad)

The Jonathan Walsh Lab is currently researching longitudinal trends of diagnostic and procedural utilization in pediatric patients with head and neck complaints. -
Laboratory for Fetal and Neonatal Organ Regeneration
Researchers in the Laboratory for Fetal and Neonatal Organ Regeneration in the Department of Surgery at the Johns Hopkins School of Medicine are studying whether cellular reprogramming, stem cells, and ex vivo modeling can be applied to improve organ regeneration in pediatric surgical patients. To execute these aims, the lab collaborates with developmental biologists and biomedical engineers throughout the country and employs cutting-edge molecular strategies and pre-clinical animal models. -
Shivani Patel Lab
Investigators in the Shivani Patel Lab study ways to improve intraoperative resuscitation during pediatric surgeries.
