Summary of "Bone-marrow mononuclear cell therapy in a mouse model of amyotrophic lateral sclerosis: Functional outcomes from different administration routes."

Amyotrophic lateral sclerosis (ALS) is a chronic degenerative disease that mainly affects motor neurons, leading to progressive paralysis and death. Recently, cell therapy has emerged as a therapeutic alternative for several neurological diseases, including ALS, and bone-marrow cells are one of the major cell sources. Considering the importance of pre-clinical trials to determine the best therapeutic protocol and the hope of translating this protocol to the clinical setting, we tested bone-marrow mononuclear cell (BMMC) therapy administered by different routes in the SOD1 model of ALS. BMMCs were isolated from non-transgenic, age matched animals and administered intravenously (IV), intramuscularly (IM), and intravenously and intramuscular concomitantly (IV+IM). BMMC therapy had no significant beneficial effects when injected IV or IM, but delayed disease progression when these two routes were used concomitantly. BMMC IV+IM treatment reduced the number of microglia cells in the spinal cord and partially protected of neuromuscular-junction innervation, but had no effect in preventing motor-neuron loss. This study showed that injection of BMMC IV+IM had better results when compared to each route in isolation, highlighting the importance of targeting multiple anatomical regions in the treatment of ALS.

In vivo deuterium labelling in mice supports a dynamic model for memory T-cell maintenance in the bone marrow.

The maintenance and dynamics of memory T-cells in the bone marrow are a matter of ongoing debate. It has been suggested that memory T-cells in the bone marrow are maintained as long-lived, quiescent c...

Bone marrow mononuclear cell telomere length in acute myeloid leukaemia and high-risk myelodysplastic syndrome.

Short telomere length is a known risk factor for developing clonal hematopoietic stem cell disorders, probably due to chromosomal instability. We tested the hypotheses that bone marrow mononuclear cel...

Aging and lineage allocation changes of bone marrow skeletal (stromal) stem cells.

Aging is associated with decreased bone mass and accumulation of bone marrow adipocytes. Both bone forming osteoblastic cells and bone marrow adipocytes are derived from a stem cell population within ...

Medical and Biotech [MESH] Definitions

Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as MULTIPLE MYELOMA. Most bone marrow neoplasms are metastatic.

Mononuclear phagocytes derived from bone marrow precursors but resident in the peritoneum.

Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.

Agents that destroy bone marrow activity. They are used to prepare patients for BONE MARROW TRANSPLANTATION or STEM CELL TRANSPLANTATION.

The transference of BONE MARROW from one human or animal to another for a variety of purposes including HEMATOPOIETIC STEM CELL TRANSPLANTATION or MESENCHYMAL STEM CELL TRANSPLANTATION.
