Analysis of candidate human blood stem cells in "humanized" immune-deficiency SCID mice
1Systemix Inc., Palo Alto, CA 94303.
Immune deficient SCID mice support the hematopoietic development of surgically implanted human fetal thymus and bone. The usability of the resulting SCID-hu hematolymphoid chimaera as an assay system for human candidate blood stem cells was suggested by the observation that allogeneic CD34+ cells sorted from fetal liver and bone marrow can engraft and differentiate in the transplanted human thymus and bone marrow. The SCID-hu mouse has been further used, in combination with a mouse bone marrow stromal cell line that supports human myeloid and B lymphoid differentiation in vitro, to identify a minor subset of fetal CD34-expressing cells that exhibit multilineage hematopoietic potentialities.
