Title: Microfluidic synthesis of retinoic acid-loaded nanoparticles for neural differentiation of trabecular meshwork mesenchymal stem cell
Author: P. Mohammadi, A. Rahmani, M. Habibizadeh, S. Nadri

Abstract: OBJECTIVES: This study aimed to fabricate the PCL-nanoparticles (NPs) loaded retinoic acid (RA) using the microfluidic system for successful cellular uptake and induction of neuronal differentiation of trabecular meshwork mesenchymal stem cells (TMMSCs).
METHODS: A microfluidic system used to synthesize RA-loaded NPs, DLS, FTIR, TEM, and UV-spectroscopy was recruited to characterize and study the release of RA. Also, the toxicity, cellular uptake, and neuronal differential of TMMSCs have been assessed.
RESULTS: According to the obtained results, the spherical NPs (117.6±0.35 nm, ‒19.4±5.3) and RA-loaded NPs (121.6±0.75 nm, ‒23.6±1.3) were synthesized successfully by microfluidic system. 7.8±2.04 % of RA was loaded in NPs, and 25 % was released in the first four hours. Thus, the NPs have been successfully internalized into the stem cells, leading to a significant increase in neural genes and protein (β Tubulin III and Map-2) expression.
CONCLUSION: Our study’s harvested results have represented valid data for practical use of microfluidic systems in the term of NPs loaded RA synthesis and its successful function to cellular internalization and euronal differentiation of TMMSCs (Tab. 2, Fig. 10, Ref. 46).
