Foreword to MSC Exosomes
Understanding mesenchymal stem cell (MSC) exosomes requires recognition of their relevance across various scientific and medical fields. These exosomes, which are essentially small membrane-bound vesicles secreted by MSCs, play pivotal roles in intercellular communication. They can shuttle molecular information between cells, influencing numerous biological activities including immune responses, tissue regeneration, and even metabolic regulation. This introduction aims to set the stage for deeper explorations into MSC exosomes throughout the article, laying bare the significance of this topic.
Definition and Origin
MSC exosomes are nano-sized vesicles that are released by mesenchymal stem cells into the extracellular environment. Defined as endosomal-derived structures, their diameter typically ranges from 30 to 150 nanometers. The origin of these exosomes can be traced back to the endosomal pathway of MSCs. This process involves the formation of intraluminal vesicles within multivesicular bodies, which are then secreted when these bodies fuse with the plasma membrane of the cell.
In a more straightforward sense, if we visualize a cell as a busy kitchen, MSCs are the chefs preparing little parcels (exosomes) with unique ingredients (proteins, lipids, and RNAs) inside them. These parcels are then sent out to communicate with other cells, much like delivering dishes to a table of diners.
Historical Context

Grasping how these exosomes form offers insight into their cargo composition and potential impacts on neighboring cells.
Formation Mechanisms
Exosomes originate from a series of extensive cellular processes. It all begins with the inward budding of the cell membrane, resulting in the creation of early endosomes. Within these endosomes, further invagination leads to the formation of multivesicular bodies (MVBs). It’s the MVBs that take center stage in exosome biogenesis.
When the MVBs fuse with the plasma membrane, they release their internal vesicles into the extracellular space, thereby forming what we call exosomes. The regulation of this process is extremely intricate, influenced by various factors including cellular stresses, signaling pathways, and the specific microenvironment of the MSCs. For instance, hypoxic conditions can enhance exosome production, indicating that the local environment can shape the biogenesis of these vesicles.
Moreover, proteins such as Tsg101 and Alix play pivotal roles in the formation and release of exosomes. They interact with the endosomal sorting complexes required for transport (ESCRTs), a system that orchestrates the budding off of exosomes from MVBs. Each of these mechanisms contributes significantly not only to the quantity of exosomes produced but also to the diversity of their biological activity.
