Effect of Controlled Microtopography on Osteogenic Differentiation of Mesenchymal Stem Cells
Table 2
Summary of MSC differentiation regulated by microgroove.
| Material | Groove (μm) | Ridge width (μm) | Depth (μm) | Cell type | Main results |
| PDMS | 0.65–6 | 0.35–7 | 0.1–2 | Ad-MSCs | Groove width of 4 μm and ridge width of 2 μm promotes osteogenic differentiation greatly | Ti | 7–20 | 3–20 | 2 | mMSCs | Groove width of 7 μm and ridge width of 3 μm can most effectively align the cells and promote osteogenic differentiation | Polyimide | 2–15 | 2–15 | 5 | hMSCs | Groove width of 10 μm and ridge width of 10 μm can promote osteogenic differentiation whereas 15 μm ridges supports adipogenic differentiation | Ti | 30 and 60 | — | 10 | hMSCs | Groove width of 30 or 60 μm enhances osteogenic differentiation | Ti | 60 | — | 10 and 20 | hMSCs | Groove width of 60 μm and depth of 10 μm allows for the highest levels of adhesion and osteogenic differentiation on day 21 | PCL | 50, 100, and 200 | — | 25, 50, and 100 | hMSCs | Groove width >100 μm slightly increases the ALP activity level of MSCs. |
