【 摘 要 】
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease lacking effective therapies. Cell replacement therapy has been suggested as a promising therapeutic approach for multiple neurodegenerative diseases, including motor neuron disease. We analyzed expanded mesenchymal stem cells (MSCs) isolated from sporadic ALS patients and compared them with MSCs isolated from healthy donors. MSCs were isolated from bone marrow by Percoll gradient and maintained in culture in MSC Medium until the third passage. Growth kinetics, immunophenotype, telomere length, and karyotype were evaluated during in vitro expansion. Osteogenic, adipogenic, chondrogenic, and neurogenic differentiation potential were also evaluated. No morphological differences were observed in the MSCs isolated from donors or patients. The cellular expansion potential of MSCs from donors and patients was slightly different. After three passages, the MSCs isolated from donors reached a cumulative population doubling higher than from patients but the difference was not statistically significant. No significant differences between donors or patients were observed in the immunophenotype analysis. No chromosomal alteration or evidence of cellular senescence was observed in any samples. Both donor and patient MSCs, after exposure to specific conditioning media, differentiated into adipocytes, osteoblasts, chondrocytes, and neuron-like cells. These results suggest that extensive in vitro expansion of patient MSCs does not involve any functional modification of the cells, including chromosomal alterations or cellular senescence. Hence, there is a good chance that MSCs might be used as a cell-based therapy for ALS patients.
