https://www.selleckchem.com/products/pri-724.html Mesenchymal stem-cell (MSC)-based therapies have been recognized as promising strategies for the treatment of various injuries or diseases because of their unique characteristics, such as self-renewal, differentiation potential, and secretion of various bioactive molecules. However, MSC transplantation often results in low efficacy, including a cell viability loss and a low therapeutic activity. Alternatively, MSC spheroids have been studied to improve the viability and therapeutic activity of MSCs. Also, microencapsulation of cells can protect and retain the cells from harsh environments after transplantation. Here, MSC spheroids were formed in hyaluronic acid/alginate (HA@Alg) core-shell microcapsules and employed for neovascularization. A well-defined core-shell structure of HA@Alg microcapsules was produced by optimizing various electrospraying conditions. MSC spheroids could be spontaneously formed in the HA core of the microcapsules after 1 day of incubation. Enhanced secretion of various growth factors was found from MSC spheroids in HA@Alg. In vivo plug assay revealed the significant promotion of angiogenesis by MSC spheroids in HA@Alg compared to that by the controls (i.e., MSCs and MSC spheroids), which is likely because of the better retention of MSC spheroid forms in the microcapsules. Thus, the HA@Alg microcapsules embedding MSC spheroids will be greatly beneficial for various stem cell-based therapies.Magnetic hyperthermia (MH) mediated by magnetic nanoparticles is one of the most promising antitumor modalities. The past several decades have witnessed great progress for MH antitumor therapy in scientific trials and clinic applications since it was initially advanced by Gilchrist et al. The ultimate object of MH in vivo is to efficiently kill cancer cells, and hence, it is of great importance to develop an optimized cellular MH method to evaluate the therapeutic efficiency in vitro. In this study, we sys
