Conditioned Media from Human Adipose Tissue-Derived Mesenchymal Stem Cells and Umbilical Cord-Derived Mesenchymal Stem Cells Efficiently Induced the Apoptosis and Differentiation in Human Glioma Cell Lines In Vitro

Scratch assay. U251 cells were induced with ASC-CM and UC-MSC-CM for two days. The cells quickly grew over the scratch for U251 cells cultured alone. After 48 hours, the scratch was invisible. For ASC-CM and UC-MSC-CM culture, although there are still some cells growing over the scratch line, the scratch is still visible. Fewer cells are seen grown over the line.
