RNA sequencing of epidermal stem cells in Fbln7 WT vs Fbln7 KO mice
This study was performed to compare the transcriptome of epidermal stem cells in young (2 months old) and middle aged (1 year old) fibulin 7 wild type (WT) compared to fibulin 7 knockout (KO) mice. Fbln7 gene was an ECM gene significantly upregulated in aging fast-cycling stem cells and this RNA-sequencing was done to investigate the role of Fbln7 in aging epidermal stem cells. Data indicates differences in gene expressions occuring between WT and KO at 1 year old but not at 2 months old, suggesting an age dependent role of fibulin 7. At 1 year old, other matrix-related and remodelling genes were affected, together with inflammatory responses of stem cells and lineage fate abberations, as in the case of 2 years old fast-cycling epidermal stem cells. Overall design: mRNA expression analysis from epidermal stem cells of Fbln7 WT or KO mice at 2 months old compared to 1 year old
