Mesenchymal Stem cells (MSCs) derived from mouse muscle tissue and bone marrow were used in an experimental cell therapy for Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is an incurable, progressively debilitating muscular-skeletal and cardiac disease caused by a mutation in the dystrophin gene. The encoded dystrophin protein is part of a larger protein complex involved in anchoring the muscle cytoskeleton to components of the extracellular matrix. Loss of dystrophin leads to muscle wasting, and heart disease is a major cause of death in patients with DMD. Therefore, the availability of effective treatments to address cardiac function in people with DMD is vital.

The mobilization of hematopoietic stem and progenitor cells (HSPC) to the peripheral blood is an essential process enabling the collection of these cells from an easily accessible source. The use of peripheral blood as a source of stem cells has significantly improved donor safety, since it does not require a surgical procedure for cell collection, and it is associated with a significantly accelerated reconstitution of the immune system in transplant patients.

A new study shows that we may be able to boost the grafting ability in cells for people receiving a bone marrow transplant.

Allogenic stem cell transplantation is a treatment approach in people with diseases that are destructive to the bone marrow, such as multiple myeloma, leukemia, and Hodgkin´s lymphoma. The goal is to restore bone marrow after total-body chemotherapy and irradiation. The transplantation procedure involves transferring hematopoietic stem cells from compatible, healthy donors to a patient. An important complication of this procedure is rejection and destruction of the donated stem cells by the recipient’s immune system before engraftment can occur.

New clinical applications in regenerative medicine are motivating an intense interest in easily accessible sources for producing human stem cells. The 2007 breakthrough showing that induced pluripotent stem cells (iPSC) could be generated directly from adult cells has been a boon to the industry. Since that time, there has been a steady refinement of the cell culture techniques that guide the cell reprogramming process.

Stem cells are the foundation from which all other cells with specialized functions are generated. Stem cells are primarily found in the bone marrow, where they are produced, but can be induced to migrate into the peripheral blood circulation through a process known as mobilization.
