Yet according to new research into the location of bone marrow and stem cell donors around the UK, the capital may actually prove to be the most selfless region of them all.
In addition, we collected one femur and one tibia from each mouse and measured total nucleated marrow cells, total donor-derived CD45.1+ KLS hematopoietic stem cells (c-kit+ Lin− Sca-1+ cells) and recipient-origin CD45.2+ KLS cells.
Bone marrow cells from donor mice were harvested by flushing femurs and tibias and were cultured for 24 hours in transplant medium (RPMI+10% FBS+6 ng/mL IL-3, 10 ng/mL IL-6, and 10 ng/mL stem cell factor).
Recipient mice were exposed to 1200 rad of whole body irradiation, and injected intravenously with 10 million whole bone marrow cells from donor mice.
For competitive repopulation assays, B220 and CD3-depleted bone marrow cells from donor CD45.1 control mice were mixed with the same type of cells derived from either CD45.2 control or CD45.2 PDK1fl/fl/Vav-Cre+ve donor mice in 1 1 ratio.
The next morning each mouse was i.v. injected with 1.5 to 3 × 10 nucleated bone marrow cells from donor mice of wild-type, mrp1 KO, Mdr1ab DKO or Mdr1ab/Mrp1 TKO genotype.
To assess the involvement of the immune system, we conducted a bone marrow transplantation assay, in which we used irradiation to eliminate the recipient rat bone marrow in order to replace it with bone marrow cells from donor rats of the same or opposite Mcs5a genotype.

This study was designed to investigate the effect of different routes of bone marrow cell (BMC) transplantation on donor-specific tolerance induction across MHC barrier under short-term CsA monotherapy and αβTCR/CsA treatment protocols.
