Abstract

The purpose of the present study was to evaluate the neural protein expression pattern of human multipotent mesenchymal stromal cells (hMSCs) treated with forskolin (free-form/FF). The study investigated forskolin's capacity to enhance intracellular levels of cyclic adenosine monophosphate (cAMP) by activating adenylate cyclase and probably by inducing neuron-like cells in vitro. In addition, because nanotechnology is a growing field of tissue engineering, we also assessed the action of a new system called the nanostructured-forskolin (NF) to examine the improvement of drug delivery. Afterwards, the cells were submitted to low-level laser irradiation to evaluate possible photobiostimulatory effects. Investigations using the immunofluorescence by confocal microscopy and Western blot methods revealed the expression of the neuronal marker beta-tubulin III. Fluorescence intensity quantification analysis using INCell Analyzer System for beta-tubulin III was used to examine significant differences. The results showed that after low-level laser irradiation exposure, there was a tendency to increase the beta-tubulin III expression in all groups, as expected in the photobiostimulation process. Notably, this process induced for irradiation was more pronounced in irradiated nanoforskolin cells (INF) compared to non-irradiated free-forskolin control cells (NFFC). However, there was also an increase in beta-tubulin III protein expression in the groups: irradiated nanocontrol cells (INC) compared to non-irradiated free-forskolin control cells (NFF) and after treatment with non-irradiated free-forskolin (NFF) and non-irradiated nanoforskolin (NNFC). We concluded that the methods using low-level laser irradiation and/or nanoparticles showed an up-regulation of neural-protein expression in hMSCs that could be used to facilitate cellular therapy protocols in the near future.
