Research Summary
Epithelial Cell Biology, Kidney Development, Stem Cells.

Research Activities
Epithelial Differentiation During development epithelia cells are generated from non-epithelial stem cells. These epithelia all have tight junction and apical and basal polarity. Mature epithelia however are easy to recognize as being tissue-specific. This implies that a second differentiation signal is needed to specify these terminally differentiated phenotypes. We have discovered a pathway for terminal differentiation of epithelia cells. Starting with a kidney cell line, we found that an extracellular matrix protein, which we termed hensin induces terminal differentiation in epithelial cells. This protein is expressed in most epithelia. Hensin requires to be localized in the matrix to bind to tis receptor. Knockout of hensin caused defects in the terminal differentiation of the earliest embryonic epithelia.

Kidney Development During nephrogenesis, a set of mesenchyma cells convert to epithelia and then segment to form the nephron. We are studying the processes that generate and determine the segment identity and the number of nephrons.

Stem Cells We have recently identified that the mature kidney contains stem cells. We are presently isolating these stem cells with a view towards characterizing their transcriptional program.
