Effects of SMFs on nerve cells. Human umbilical vein endothelial cells (HUVECs); oligodendrocyte precursor cells (OPCs); olfactory ensheathing cells (OECs); neural progenitor cells (NPCs); and N/A, not available.
| Objects | Magnetic flux density | Magnetic field direction | Exposure time | Effects | References | |
|---|---|---|---|---|---|---|
| Humans | Satellite cells | 80 mT | Upward | 21 days | Increased gene expression of DES, MYF5, MYOD1, MYOG, MYH and ACTA1 as well as enhanced IGF1-induced increase of satellite cell proliferation | 56 |
| No effect on myogenic maturation | 57 | |||||
| Neuronal cells FNC-B4 | N/A | 120 min | Promoted neural differentiation | 52 | ||
| PC12, HUVECs | 200 mT | Parallel | 7 days | Combined MNPs promoted the proliferation and secretion of neurotrophic factors | 58 | |
| OPCs | 300 mT | Perpendicular | 2 h/day, 2 weeks | Enhanced differentiation, promoted function and neurotrophic factor release | 53 | |
| Rats | Whole animal | 10 mT | N/A | 3 weeks | Enhanced the generation of new doublecortin-expressing cells in the SVZ and neocortex | 49 |
| OECs | 30, 50, and 70 mT | Parallel or perpendicular | 36 h | Influenced the division, movement, migration direction and speed of OEC, as well as the formation and rearrangement of microtubules and actin filaments for tissue regeneration | 50 | |
| NPCs | 100 mT | N/A | 12 days | Promoted cellular self-renewal and differentiation into neurons | 51 | |
| Schwann cells | 8 T | Parallel | 60 h | Induced parallel orientation of the Schwann cells along the SMF direction | 55 | |
| Mice | NPCs | 500 mT | N/A | 7 days | Affected normal neurogenesis and promoted neurospectral differentiation as well as neuronal maturation | 54 |
