Project description:During aging, stromal functions are thought to be impaired, yet little is known whether this stems from molecular and cellular changes of fibroblasts, a major component of stroma. Using population- and single-cell whole transcriptomics, and long-term lineage tracing, we studied alterations in murine dermal fibroblasts during physiological aging under different dietary regimes known to affect longevity. We show that the identity of aged fibroblasts becomes undefined, with the distinct fibroblast states present in young skin no longer clearly demarcated. In addition, old fibroblasts not only reduce the expression of genes involved in the formation of the extracellular matrix, but intriguingly, also gain adipogenic traits, paradoxically becoming similar to neonatal pro-adipogenic fibroblasts. These age-related alterations are sensitive to systemic changes in metabolism: long-term caloric restriction prevents them in old fibroblasts in a reversible manner, whereas a high-fat diet potentiates them in young fibroblasts. Finally, inhibition of the master regulator of adipogenesis, PPARgamma, attenuates fibroblast aging in vivo, providing potential anti-aging therapeutic alternatives to caloric restriction.

Project description:We were interested in identifying proteins that are regulated in response to the extracellular matrix molecule, fibronectin, in dermal fibroblasts. To determine proteins regulated by exposure to fibronectin, primary murine dermal fibroblasts were cultured on tissue culture plastic or on tissue culture plates coated with a thin layer of fibronectin (2 μg/cm2). Fibroblasts were seeded at 35,000 cells/10 cm2 and were harvested 48 hours later. Cell pellets from these fibroblasts were shipped to Kinexus Bioinformatics Corp. (Vancouver, B.C.) where they were lysed and analyzed using the Kinex TM Antibody Microarray (KAM 1.2), which contains 800 (500 pan-specific and 300 phosphorylation site-specific) antibodies. This enabled us to identify candidate proteins regulated by exposure to fibronectin.

Project description:The current study was to determine the effects of Fibroblast Growth Factor 2 (FGF2) on the transcriptome of adult human dermal fibroblasts. Transcriptional profiles of adult human dermal fibroblasts grown in culture medium (with FGF2 or not) were compared. Comparison of the transcriptomes will allow to identify significantly differentially expressed genes exposure to FGF2, which in turn will allow for identification of the pathways affected by these factors in the human adult fibroblasts. Methods: Human dermal fibroblasts were FGF2 (10ng/ML) treatment for 48h hours. Then, the RNA was extracted for library construction Results: FGF2-responsive genes were significantly involved in ECM-receptor interaction, PI3K-Akt signaling and Hippo pathway.

Project description:MiR-132 is one of the most upregulated miRNAs in human skin wounds at the inflammatory phase of healing; however its biological role in dermal fibroblasts during wound repair has not been studied. To study the genes regulated by miR-132, we transfected miR-132 mimics (pre-miR-132) into primary human dermal fibroblasts to overexpress miR-132. We performed a global transcriptome analysis of fibroblasts upon overexpression of miR-132 using Affymetrix arrays.
