Prof. Tsvee LAPIDOT (Israel)
Born in Jerusalem Israel, B.A, Hebrew U. 1983, M.Sc. Weizmann
1985, and Ph.D. on stem cell transplantation at Weizmann
1990. Postdoctoral research 1990-1994, Toronto, Canada
with Prof. John Dick, establishment of functional preclinical
models for both normal (Lapidot & Dick et al, Science
1992) and leukemic human stem cells (Lapidot & Dick
et al, Nature 1994). in transplanted immune deficient
mice. Associate Professor in 2001 and Professor in 2006.
Over 100 refereed articles, reviews and book chapters.
Focus on regulation of human stem cell migration and development,
both normal and leukemic in functional pre-clinical models
of immune deficient NOD/SCID mice. The cross talk between
cytokines, chemokines, proteolytic enzymes and adhesion
molecules in stem cell homing, retention, release and
mobilization is currently studied. In particular the chemokine
SDF-1 and its major receptor CXCR4 which are crucial for
both human stem cell repopulation (Peled & Lapidot
et al Science 1999), clinical mobilization (Petit &
Lapidot et al Nature Immunology 2002) and the unique roles
of bone resorbing osteoclasts in stem cell regulation
(egress, recruitment and mobilization (Kollet & Lapidot
et al Nature Medicine 2006, Shivtiel & Lapidot et
al JEM 2008).
The dynamic cross talk between the nervous and immune
systems with the microenvironment which regulate stem
cells is intensively investigated (Spiegel & Lapidot
et al, Nature Immunology 2007, Spiegel & Lapidot et
al Cell Stem cell 2008).
