About Bone Marrow Transplant

Healthy bone marrow stem cells and the blood cells they create are crucial for survival, but certain diseases can affect the bone marrow, interfering with its ability to function properly. A bone marrow transplant is a process to replace unhealthy bone marrow with healthy bone marrow stem cells. Bone marrow transplant can save the lives of patients with blood cancers and genetic diseases and is a potential cure for patients with severe refractory autoimmune diseases. However, the high risks, toxic side effects and complexity of the procedure currently prevent many patients from being able to benefit. Magenta is working to address these challenges through its integrated portfolio of therapeutics.
