Immortalized multipotential mesenchymal cells and
the hematopoietic microenvironment.
Furthermore, these potentials are expanded by the notion that MSCs can exert functions other than those classically attributed to stem or progenitor cells, including establishment and support of
the hematopoietic microenvironment in vivo, as observed for bone marrow derived MSCs.

Microenvironment of
hematopoietic stem cells can be a target for myeloproliferative disorders.»
The findings, published today in Nature, demonstrate that these myeloproliferative neoplasias only appear after damage to the
microenvironment that sustains and controls the
hematopoietic stem cells — the cells that produce the cells of the blood and the immune system.
«In normal conditions, the
microenvironment is able to control the proliferation, differentiation and migration of the
hematopoietic stem cell.
The team has shown that the
microenvironment that controls
hematopoietic stem cells can be targeted for the treatment of a set of disorders called myeloproliferative neoplasias, the most prominent of which are chronic myelomonocytic leukemia (CMML), juvenile myelomonocytic leukemia (JMML), and atypical chronic myelogenous leukemia (CML).
Basic research has centered on identifying and characterizing
hematopoietic stem cells, however, it is still not clear how
hematopoietic stem cells actually work, and how they are regulated because of the complexity of the bone marrow
microenvironment.

In her project, Sipkins will investigate molecular characteristics of tissue
microenvironments, or «niches,» within the bone marrow and how normal, healthy
hematopoietic stem cells, which give rise to the many kinds of blood cells, compete with malignant cells to occupy these coveted niches.
