The research interest of the lab is to study the
development of the endocrine pancreas. The
endocrine portion of the pancreas, the islets of
Langerhans, contains several cell types. The
most abundant islet cell type is the beta cell,
which secretes insulin. In diabetes, beta cells
are lacking or insufficient. In our research,
morphological, cell biological and molecular
biological techniques are used to study various
aspects of the development of the islets of
Langerhans in rodents and in amphibians. Recent
research emphasis is on the cell lineage
relationships of various islet cell types with
the early endodermal cells of the pancreatic
primordium. The goal of these studies is to
identify progenitor or stem cells that can
regenerate beta cells or to find ways to induce
the regeneration of beta cells.
