First Successful Injection of Cultured Red Blood Cells in Human Donor and other interesting bioscience headlines (Aug & sept 2011)

[UF Umeoguaju]

Good day,
Below are some of the most interesting happenings around the world of biosciences last month!

***********Researcher's First Successful Injection of Cultured Red Blood Cells in Human Donor***********

For the first time, researchers have successfully injected cultured red blood cells (cRBCs) created from human hematopoietic

stem cells (HSCs) into a human donor, according to study results published in Blood, the Journal of the American Society of

Hematology (ASH). As the global need for blood continues to increase while the number of blood donors is decreasing, these

study results provide hope that one day patients in need of a blood transfusion might become their own donors.

Using HSCs (stem cells that form all blood cell types) from one human donor, a Paris-based research team successfully

generated billions of cRBCs in a petri dish with the aid of specific growth factors that regulate the proliferation and

maturation of HSCs into red blood cells. Seeking to prove that the cRBCs were capable of reaching full maturation in the

body, the researchers then injected the cells into four mouse models and confirmed that the cells were able to progress

through the full maturation process. Using a volunteer donor, the researchers then repeated the process of creating another

set of cRBCs and injected the cells back into the donor's own body to assess their survival in a human. After five days, the

survival rate of the cRBCs in the donor's bloodstream was between 94 and 100 percent and, after 26 days, the rate was between

41 and 63 percent, comparable to the average 28-day half-life of normal native red blood cells. These results demonstrate

that the lifespan and survival rate of cultured cells are similar to conventional red blood cells, further supporting their

validity as a possible source of transfusion.
