Cell monitoring and cell localization can be potentially
achieved by the internalization of magnetic nanoparticles (MNPs) in
the cells. This might allow for the investigation of migratory patterns
through tracking studies, the targeting of particle-labelled cells to
desired locations via the application of an external magnetic field and,
finally, for activation stem cells to initiate desired cellular responses as
inducing the differentiation process [1]. This study focus on determining
the effect of magnetic stimulation in human adipose stem cells
(hASCs) differentiation towards tendon cells. Firstly, the MNPs uptake
by the cell and magnitude/frequency of the external magnetic field was
verified. Afterwards, initial studies on understanding the endocytic
mechanisms involved in the uptake of MNPs were performed. For this,
cells were treated with pharmacological inhibitors before exposure to
fluorescent labeled MNPs.
