The discovery that zebrafish produce natural chemicals that enhance production of blood-forming stem cells may translate rapidly into new treatments to increase the success what chemicals are in human blood bone marrow or cord blood transplants in humans. The research team, which was led by Leonard Zon, a Howard Hughes Medical Institute researcher at Children's Hospital in Boston, published its findings in the June 21,issue of the journal Nature.

Trista North, a postdoctoral fellow in Zon's laboratory, was lead author. Using drugs that enhance PGE2 to amplify the number of stem cells in a cord [blood] sample could enable use of only one cord in such patients. In their experiments, the researchers were searching for compounds that would increase the production of blood-forming, or hematopoietic, stem cells HSCs.

Zon said that such compounds could be clinically important in enhancing success of bone marrow and cord blood transplantation. One of the aims bloof bone marrow transplantation is to restore the immune systems of patients whose blood cells have been depleted by cancer therapy. So, Trista and I came up with the idea of conducting a mass screening of chemicals from a library to see whether we casual meeting meaning in gujarati find any that increased the quantity of stem cells.

Chemical researchers screened a library of 2, chemicals, about a third of which are already FDA-approved, said Zon. They began by placing fish embryos in the tiny wells of a culture dish. Once the embryos were in place, the researchers added one of the chemicals, stained the embryos for stem cells, and observed whether the chemical enhanced or decreased stem cell production. The scientists identified 35 compounds chmeicals increased HSC production and 47 that decreased it.

The result of the screening also yielded an important discovery about the regulatory mechanism for stem cells, said Zon. When they administered blpod long-acting version of PGE2 to fish embryos, they saw a considerable enhancement of stem cell what chemicals are in human blood. In additional studies with both adult zebrafish and mice, they found that the long-acting PGE2 greatly enhanced HSC production. In particular, on they transplanted both PGE2-treated whqt untreated stem cells into what chemicals are in human blood, the treated cells far outperformed the untreated cells in happy 4/20 day images ability to proliferate.

The researchers also found that decreasing expression of two regulators of PGE2—cox 1 and cox 2—also decreased stem cell production. Chsmicals finding is important for human bone marrow recipients, because pain medications such as aspirin and ibuprofen are cox inhibitors, said Zon. While the HSC-enhancing drugs they identified could find use in aiding marrow transplantation, they will likely be especially important in cord blood transplantation, said Zon. In this treatment, stem cells from umbilical cord blood are transplanted to restore the immune blopd in hmuan patients.
