研究目的: |
人类光老化皮肤的公共单细胞 RNA 测序数据,并将其与定量原位多重免疫荧光技术相结合,了解光老化过程中内皮细胞驱动的血管重塑机制。 |

|
Objectives of Study: |
To comprehend the mechanism of endothelial cell-driven vascular remodeling during photoaging, we sequenced the public single-cell RNA of human aging skin and integrated it with quantitative in situ multiplex immunofluorescence technology. |
