| Study Title | Analysis of Metabolites Secreted from Fibroblast Young Cells |
| Study Summary | In this experimental study, we aimed to uncover the factors in young cell secretions that trigger the reverse aging of mid-old cells, co-culturing them and observing a striking transformation, although we could not identify the specific factors responsible for this rejuvenation |

| Project Title: | Mid-Old Cells are Potential Target for Anti-aging Interventions in the Elderly |
| Project Summary: | The biological process of aging is thought to result in part from accumulation of senescent cells in organs. However, the present study identified a subset of fibroblasts and smooth muscle cells which are the major constituents of organ stroma neither proliferative nor senescent in tissues of the elderly, which we termed “mid-old status” cells. Upregulation of pro-inflammatory genes (IL1B and SAA1) and downregulation of anti-inflammatory genes (SLIT2 and CXCL12) were detected in mid-old cells. In the stroma, SAA1 promotes development of the inflammatory microenvironment via upregulation of MMP9, which decreases the stability of epithelial cells present on the basement membrane, decreasing epithelial cell function. Remarkably, the microenvironmental change and the functional decline of mid-old cells could be reversed by a young cell-originated protein, SLIT2. Our data identify functional reversion of mid-old cells as a potential method to prevent or ameliorate aspects of aging-related tissue dysfunction. |
