| Outline of Final Research Achievements |
The findings of this study demonstrated that cHCECs are composed of a dysregulated expression of a hierarchy of miR clusters, probably due to the presence of cell state transition (CST) paralleled with the reduced expression of CD44 and SASP. The assay of miRs secreted in CS, with further extended selection, may distinguish the cell-state-transitioned CD44++~+++ cHCEC from CD44- effector cells applicable in a cell-injection therapy for corneal endothelial dysfunctions. Secreted miRNA profiles among morphologically-diverse cHCEC SPs proved useful for individual distinction.It was found that the 3 to 6month long term outocome of corneal transplantartion could be predicted by the cytokine profile before the operation, especially by PDGFbb, IFNg and IL-17in aqueous humors. Five soluble form of miRNAs were identified to be responsible for the elevation of SASP in aqueous humors.
