Abstract

Objective: This study aimed to isolate and culture SADS cells, investigate their neurogenic capacity and evaluate their application for nerve tissue engineering. Materials and Methods: In this experimental study, SADS cells were isolated from human adipose tissue. After 7-day treatment of SADS cells with insulin, indomethacin and isobutylmethylxanthine, neurogenic differentiation of SADS cells was investigated. During this study, Poly (ϵ-caprolactone) (PCL) and PCL/gelatin nanofibrous scaffolds were fabricated using electrospinning and subsequently nanofibrous scaffolds were coated with platelet-rich plasma (PRP). SADS cells were also seeded on nanofibrous scaffolds and neurogentic differentiation of these cells on nanofibers was also evaluated. Effect of PRP on proliferation and differentiation of SADS cells on scaffolds was also studied. Results: Our results showed that after 7-day treatment of SADS cells with insulin, indomethacin and isobutylmethylxanthine, SADS cells expressed markers characteristic of neural cells such as nestin and neuron specific nuclear protein (NEUN) (as early neuronal markers) as well as microtubule-associated protein 2 (MAP2) and neuronal microtubule-associated (TAU) (as mature neuronal markers) while mature astrocyte maker (GFAP) was not expressed. MTT assay and SEM results showed that incorporation of gelatin and PRP into the structure of nanofibrous scaffolds has a significant positive influence on the bioactivity of scaffolds. Our results also showed neurogentic differentiation of SADS cells on scaffolds. Conclusion: Our results demonstrated that SADS cells have potential to differentiate into early and mature progenitor neurons, in vitro. PCL/gelatin/PRP was found to be a promising substrate for proliferation of SADS cells and differentiation of these cells into neural cells which make these scaffolds a candidate for further in vivo experiments and suggest their application for nerve tissue engineering. © 2018 Royan Institute (ACECR).
