Multipotent mesenchymal stem cells (MSCs) are an attractive candidate for regeneration of damaged cells, tissues, and organs. Due to limited availabilities, MSC populations must be rapidly expanded to satisfy clinical needs. However, senescence attributed to extensive in vitro expansion compromises the regenerative and therapeutic potential of MSCs. In this chapter, we describe a step-by-step protocol that aims to induce adipogenic and osteogenic differentiation of in vitro aged human MSCs and highlight noteworthy issues that may arise during the process.
