Abstract

The present research aims to design and develop a sustained drug release system to support the long-term proliferation of human adipose-derived stem cells (hADSCs) without losing their stemness and entering the cellular senescence through providing typical cell culture conditions. For this purpose, Curcumin-loaded mesoporous silica nanoparticles (CUR@MSNs) incorporated into Poly-ε-Caprolactone/Gelatin (PCL/GEL) hybrid were prepared via blend electrospinning and their impact was evaluated on cell adhesion, viability, proliferation and also the expression of senescence markers and stemness genes after a long-term in vitro culturing. The in vitro release findings proved that the MSNs incorporated into the electrospun nanofibers (NFs) allowed a sustained release of CUR. According to MTT and PicoGreen assays, the significant metabolic activity and proliferation of hADSCs were detected on CUR@MSNs-NFs after 14 and 28 days of incubation. Furthermore, CUR@MSNs-NFs showed better adhesion and spreading of hADSCs compared to other types of NFs. The sustained and prolonged delivery of CUR inhibited the stem cell senescence through the down-regulation of p16INK4A and up-regulation of hTERT. It also led to an increased stemness potency in gr...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
