Frederick Anokye-Danso Lab
The Frederick Anokye-Danso Lab investigates the biological pathways at work in the separation o...f human pluripotent stem cells into adipocytes and pancreatic beta cells. We focus in particular on determinant factors of obesity and metabolic dysfunction, such as the P72R polymorphism of p53. We also conduct research on the reprogramming of somatic cells into pluripotent stem cells using miRNAs. view more

Gabsang Lee Lab
Human induced pluripotent stem cells (hiPSCs) provide unprecedented opportunities for cell repl...acement approaches, disease modeling and drug discovery in a patient-specific manner. The Gabsang Lee Lab focuses on the neural crest lineage and skeletal muscle tissue, in terms of their fate-determination processes as well as relevant genetic disorders.
Research Areas: stem cells, human-induced pluripotent stem cells, genomics, drugs, muscular dystrophy, familial dysautonomia
Previously, we studied a human genetic disorder (familial dysautonomia, or FD) with hiPSCs and found that FD-specific neural crest cells have low levels of genes needed to make autonomous neurons--the ones needed for the "fight-or-flight" response. In an effort to discover novel drugs, we performed high-throughput screening with a compound library using FD patient-derived neural crest cells.
We recently established a direct conversion methodology, turning patient fibroblasts into "induced neural crest (iNC)" that also exhibit disease-related phenotypes, just as the FD-hiPSC-derived neural crest. We're extending our research to the neural crest's neighboring cells, somite. Using multiple genetic reporter systems, we identified sufficient cues for directing hiPSCs into somite stage, followed by skeletal muscle lineages. This novel approach can straightforwardly apply to muscular dystrophies, resulting in expandable myoblasts in a patient-specific manner.

Kunisaki Lab
The Kunisaki lab is a R01-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 (lab manager); Lynn Zhou, PhD (postdoc), Shelby Sferra, MD, MPH (postdoc); Annalise Penikis, MD (postdoc)

Zack Wang Lab
The Wang lab focuses on the signals that direct the differentiation of pluripotent stem cells, ...such as induced-pluripotent stem (iPS) cells, into hematopoietic and cardiovascular cells. Pluripotent stem cells hold great potential for regenerative medicine. Defining the molecular links between differentiation outcomes will provide important information for designing rational methods of stem cell manipulation. view more
