Hematopoietic Stem Cells
High number of circulating CD34+ cells in
patients with myelophthisis
Six patients with bone marrow micrometastases
from solid cancers presented with increased numbers
of circulating CD34+ cells; the CD34+ cell
counts were very high in some cases. By contrast,
no patient with metastatic cancer without bone
marrow involvement showed raised numbers of
circulating hemopoietic progenitors.
