Objective:To evaluate the effect of low-level laser irradiation on the proliferation and possible nuclear morphological changes of mouse mesenchymal stem cells.Methods: Mesenchymal stem cells derived from bone marrow and adipose tissue were submitted to two applications (T0 and T48 hours) of low-level laser irradiation (660nm; doses of 0.5 and 1.0J/cm2). The trypan blue assay was used to evaluate cell viability, and growth curves were used to analyze proliferation at zero, 24, 48, and 72 hours. Nuclear alterations were evaluated by […]

Objective:To compare human mesenchymal stem cells obtained from reusable and disposable filters and to characterize them according to the criteria of the International Society of Cellular Therapy.METHODS:Human mesenchymal stem cells were isolated from bone marrow collection reusable sets and compared with those obtained from disposable sets by washing the filters with cell culture media. The isolated cells were characterized according to the criteria of the International Society of Cellular Therapy using flow cytometry, differentiation in vitro, and cytochemistry techniques.RESULTS:Samples were […]
