👉 The term "posteromesia" is a biological term used to describe the development of new cells within an organism's body. It refers specifically to the process by which stem cells, also known as mesenchymal or epithelial cells, differentiate into specialized cells that are involved in tissue formation and repair. In this context, "postersomes" refer to the specialized structures present on the surface of these newly formed cells, which serve as a barrier against extracellular matrix (ECM) degradation
