The physiochemical properties and toxicity of DPs were evaluated by DLS, AFM, FESEM and MTT assay. In order to create a suitable environment for stem cell growth and differentiation, poly-l-lactic acid (PLLA) and poly-l-lactic acid/poly (ethylene oxide) (PLLA/PEO) scaffolds containing hydroxyapatite nanoparticles (HA) and DPs were fabricated by the electrospinning method. The osteogenic potency of the scaffolds on human adipose tissue-derived mesenchymal stem cells (hASCs) was investigated.Results: The results revealed that tuning the physical properties of DPs by adjusting flow parameters in microfluidic platform can easily improve the cell viability compared to conventional bulk mixing method. Also, the result showed that the presence of HA and DPs in PLLA/PEO scaffold enhanced alkaline phosphatase (ALP) activity and increased the amount of deposited Ca, as well as, related to osteogenesis gen markers.Conclusion: This study indicated that on using the MF platform in preparation of DPs and loading them along with HA in PLLA/PEO scaffold, the osteogenic differentiation of hASCs could be tuned.Keywords: microfluidic, dendriplex, nanofibrous scaffolds, bone tissue engineeringDoosti-Telgerd MMahdavi FSMoradikhah FPorgham Daryasari MBayrami Atashgah RDolatyar BAkbari Javar HSeyedjafari EShabani IArefian ENajafi FAbdi YAmini MDove Medical Pressarticlemicrofluidicdendriplexnanofibrous scaffoldsbone tissue engineering.Medicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 2633-2646 (2020)
