Upregulation of Flt3 expression within the bone marrow Lin(-)Sca1(+)c-kit(+) stem cell compartment is accompanied by loss of self-renewal capacity
(2001) In Immunity 15(4). p.659-669- Abstract
- Flt3 has emerged as a potential regulator of hematopoietic stem cells (HSC). Sixty percent of cells in the mouse marrow Lin(-)Sca1(+)c-kit(+) HSC pool expressed flt3. Although single cell cloning showed comparable high proliferative, myeloid, B, and T cell potentials of Lin(-)Sca1(+)c-kit(+)flt3(+) and Lin(-)Sca1(+)c-kit(+)flt3(-) cells, only Lin(-)Sca1(+)c-kit(+)flt3(-) cells supported sustained multilineage reconstitution. In striking contrast, Lin(-)Sca1(+)c-kit(+)flt3(+) cells rapidly and efficiently reconstituted B and T lymphopoiesis, whereas myeloid reconstitution was exclusively short term. Unlike c-kit, activation of flt3 failed to support survival of HSC, whereas only flt3 mediated survival of Lin(-)Sca1(+)c-kit(+)flt3(+)... (More)

Phenotypic and functional analysis support that Lin(-)Sca1(+)c-kit(+)flt3(+) cells are progenitors for the common lymphoid progenitor. Thus, upregulation of flt3 expression on Lin(-)Sca1(+)c-kit(+) HSC cells is accompanied by loss of self-renewal capacity but sustained lymphoid-restricted reconstitution potential. (Less)
