• Frederick Anokye-Danso Lab

  The Frederick Anokye-Danso Lab investigates the biological pathways at work in the separation of 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.

  Research Areas: stem cells, obesity, metabolism, biology

• Gabsang Lee Lab

  Human induced pluripotent stem cells (hiPSCs) provide unprecedented opportunities for cell replacement 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.
  
  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 ne...ural 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

• The Koliatsos Lab

  Founded in the late 1980s, our Lab has been exploring the fundamental mechanisms of neural responses to traumatic and degenerative signals as well as mechanisms of neural repair. Our current interests include: traumatic brain injury and models; mechanisms and treatments of traumatic axonopathies; molecular neuropathology of traumatic brain injury; induced pluripotent stem cells as models of disease.

• 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.
