Core Tip

Core tip: Cell therapy is a promising treatment for the diseases caused by cell degeneration or death. However, the transplanted cells often develop fibrosis or are absorbed and cannot survive long. It is not simply because of seed cells, but also due to the cell microenvironment. How to reconstruct the stem cell microenvironment and strengthen its combination with the transplanted cells is the key to successful cell therapy. We will discuss the importance of the stem cell microenvironment for cell-based therapy in ocular diseases and introduce the progress of cell therapy for ocular diseases.
