Scientists have successfully developed technology to create human blood cells in the laboratory from stem cells, opening up new treatment opportunities for cancer and blood diseases.
Australian scientists have just announced a medical breakthrough, hailed as a "world first," opening up prospects for more effective treatments for cancer and blood disorders, and potentially significantly reducing reliance on traditional bone marrow transplants.
According to an announcement from the Murdoch Children's Research Institute, scientists there have successfully developed a technology to create human blood cells in the laboratory from stem cells, thereby opening up the possibility of using stem cell transplantation as an alternative to bone marrow transplantation for patients who cannot find a suitable donor.
Professor Andrew Elefant, the lead researcher, said that creating blood stem cells has long been considered one of the biggest challenges in biomedical science because this type of cell is extremely rare and very difficult to cultivate under artificial conditions.
He stated that after more than 25 years of research, the scientific team has successfully recreated the stages of embryonic development in the laboratory to form human blood cells.
According to the research team, the new technology not only expands access to treatment for patients needing stem cell transplants but also has the potential to repair genetic defects related to the development of blood stem cells – the cause of many dangerous diseases.
Furthermore, this technology is expected to open up a wide range of immunological applications in the future, especially in the treatment of cancer and complex blood disorders.
Professor Elefant said that laboratory tests have shown these cells are capable of regenerating the blood system in animal models, which is considered an important step before moving to clinical trials on humans.
