Role of WNT signaling in normal and malignant hematopoiesis.

The WNT pathway is a powerful signaling pathway that plays a crucial role in cell fate determination, survival, proliferation and movement in variety of tissues. Abnormalities in the WNT signaling pathway have been implicated in a number of diseases, most notably cancer. Recent exciting evidence suggests that WNT signaling also plays an important role in hematopoietic stem cell self-renewal and progenitor development. In this review we discuss current state of knowledge on WNT signaling in hematopoiesis and extend our focus on aberrant WNT signaling in hematological malignancies.
