Abstract excerpt
We created parabiotic mice, joining ROSA26 and PeP3b animals, to study the trafficking of hematopoietic stem cells (HSCs) from marrow to blood and their return to marrow. The transfer of HSCs was assayed by secondary marrow transplantation and was 1.0% to 2.5% after 3, 6, 8, and 12 weeks. Thus, HSC homeostasis is primarily maintained by the retention of stem cells derived from replication events within the...
