Our program brings together basic scientists and clinicians studying
stem cells in a variety of adult and developing organ systems. The goal is
to understand and exploit their remarkable capacity to maintain healthy
tissues and to replace cells lost by disease or injury. Program highlights
- Pioneering studies on therapeutic applications of bone marrow and cord blood stem cells
- Use of bioengineered scaffolds to grow new tissues from stem cells
- High resolution imaging of stem cells in living tissues, and their relationship with blood vessels and nerve cells migrating into developing organs
- Identification of natural signals that control how stem cells behave
- Investigations of germline stem cells and their regulation by RNA
binding proteins and miRNAs
- Learning from zebrafish, which have much greater capacity than humans to regenerate organs after injury
- Studying how cancers arise from, and can be maintained by, stem cells
Cell Biology is hiring a tenure-track Assistant or Associate Professor with a strong record of creativity and productivity in developmental and/or regenerative biology. Applicants should submit a curriculum vitae, a 3-page summary of accomplishments and research plans, a teaching statement, and at least 3 letters of recommendation by November 15, 2015. Applications should be submitted via Academic Jobs Online. Questions may be directed to Ken Poss or Brigid Hogan.
Executive Director Search
The new tissue regeneration initiative at Duke is hiring an Executive Director, an Associate in Research position at Duke University, to work closely with the Director, Co-Directors, and faculty members to promote and integrate discovery research, training, and applications in the broad field of tissue regeneration. We invite applications from candidates who have a Ph.D. and postdoctoral research experience in the relevant areas of developmental biology, stem cell biology, or tissue regeneration to submit a cover letter, curriculum vitae, summary of research accomplishments and any administrative leadership experience, and a list of at least three references to Academic Jobs Online.
Questions may be directed to Ken Poss.
Niche regulation of new neurons production in the adult brain
Robust production of new neurons continues in the adult rodent brain, but how this is sustained remains unknown. Researchers in Dr. Chay T. Kuo’s laboratory found that self-assembly of radial glia into support structures for adult stem cells is critical for continued neurogenesis. More...
Zebrafish heart regeneration
During heart regeneration in zebrafish, retinoic production in endocardial and epicardial cells localizes to areas of tissue damage, where it promotes cardiomyocyte proliferation. More...
Intestinal Crypt Proliferation
Stem cell/transit amplifying compartments (green) reside in the base of each mouse intestinal crypt. These cells give rise to the multiple lineages of the intestinal epithelium (Lechler lab). More...
Lung epithelial stem cell regulation
The airways of the lung are lined by an epithelium that contains large numbers of cells specialized for making and secreting glycoproteins and mucus, as well as multiciliated cells that remove the mucus and the particles trapped in it. More...
Role of immune cells in the spermatogonial stem cell niche
In addition to their roles in immune and inflammatory responses, macrophages have diverse functions in development. In reproductive biology, macrophages have been implicated in ovarian follicular growth and in Leydig cell function, but their role in spermatogonial differentiation has not been examined. More...
Drosophila hindgut repair
The fruit fly Drosophila has long been a leading genetic model for stem cell research. However, until recently no Drosophila models existed for study of mechanisms by which adult organs lacking active stem cells repair damaged tissue.
Indispensible pre-mitotic endocycles promote aneuploidy in the Drosophila rectum
Time lapse imaging of a tripolar division during developmental organ regeneration in the Drosophila hindgut. These divisions occur in cells with extra copies of the genome (polyploid cells) and produce an adult organ in which many of the cells have variable, imbalanced chromosome numbers (aneuploid cells). DNA is in purple, and centrosomes and cell membranes are in green.
