Project description:Fibroblasts are widely used cells for regenerative medicine in clinics, such as gingival or facial skin treatment. In fact, fibroblasts are considered as a mixture of various types of cells with "spindle shape" and there is no available clear marker. Gingival and dermal fibroblasts are similar in their morphology and function; however it is considered that the cultured cells retain their original characteristics depending on the origin, which may contribute to the differential therapeutic effects. For example, gingival wounds are known to heal relatively quickly with less scar formation compared with skin, which may imply their higher capability for regeneration as a therapeutic effect. The reason for this phenomenon may be partly due to characteristic differences between gingival and dermal fibroblasts including the expression of migration stimulating factor and matrix formation but these differences remain largely unknown. Recently, the characteristics of dermal fibroblasts have been reported to be different depending on body sites, such as face, trunk and plamoplantar skin. Although the expression of fibronectin and their splicing variants were known to be different between trunk and oral mucosal fibroblasts, there is still no detailed report on the functional differences between gingival and dermal fibroblasts. In this study, we investigated differential gene expression in normal gingival and dermal fibroblasts using DNA microarray to investigate the difference between the vague fibroblast-type cells from different tissue origin to achieve higher therapeutic effect in cell therapy.

Project description:The periodontium undergoes age-related cellular and clinical changes, but the involved genes are not yet known. Here, we investigated age-related genetic changes in gingiva at the transcriptomic level. Genes that were differentially expressed between young and old human gingiva were identified by RNA sequencing and verified by real-time PCR. A total of 1939 mRNA transcripts showed significantly differential expression between young and old gingival tissues. Matrix metalloprotease (MMP) regulation was the top pathway involved in gingival aging. MMP3, MMP9, MMP12, and MMP13 were upregulated in old gingival tissues, concomitantly with interleukin-1 beta (IL1B) expression. In vitro experiments using human gingival fibroblasts (hGFs) showed that MMP12 was upregulated in old hGFs compared to young hGFs. Moreover, the MMP3, MMP9 and IL1B levels were more highly stimulated by infection with the oral bacterium, Fusobacterium nucleatum, in old hGFs compared to young hGFs. Collectively, these findings suggest that, in gingiva, the upregulation of MMP12 may be a molecular hallmark of natural aging, while the upregulations of MMP3, MMM9, and IL1B may indicate externally (e.g., infection)-induced aging. These findings contribute to our understanding of the molecular targets involved in gingival aging.

Project description:The oral gingival barrier is a constantly stimulated and dynamic environment where homeostasis is often disrupted, resulting in inflammatory periodontal diseases. Type 2 diabetes (T2D), a risk factor for periodontitis, has been reported to be associated with barrier dysfunction, but the effect and underlying mechanism are inconclusive. Herein, we performed single-cell RNA sequencing (scRNA-seq) of gingiva from leptin receptor-deficient (db/db) mice to understand the heterogeneity of gingival barrier in the context of T2D. Periodontal health of control mice is characterized by populations of Krt14+-expressing epithelial cells and Col1a1+-fibroblasts mediating immune homeostasis primarily through the enrichment of innate lymphoid cells. The db/db mice exhibit an impaired gingival barrier with spontaneous periodontal bone loss, and a decreased proportion of epithelial/stromal cells. We further observed stromal, particularly fibroblast immune hyperresponsiveness linked to recruitment of myeloid cell populations in gingiva from T2D mice. Analysis of ligand-receptor interaction pairs suggested inflammatory signaling between fibroblasts and myeloid cells, a main driver of diabetes-induced periodontal damage. Moreover, the “Immune-like” stromal cells contributed to gingival Th17/IL-17 hyperresponsiveness in T2D. Our work reveals transcriptional diversity of stromal cells and interaction with innate immune cells in T2D, and uncovers the “immune-like” fibroblast subsets participating in barrier homeostasis at the diabetic gingiva.

In this study, we investigated differential gene expression in normal gingival and dermal fibroblasts using DNA microarray to investigate the difference between the vague fibroblast-type cells from different tissue origin to achieve higher therapeutic effect in cell therapy. Gingival and dermal tissues were collected from healthy patients. After successive stages primary culture and RNA extraction and hybridization on Affymetrix microarrays (Genome Focus Array). Dermal and gingival tissues were obtained from healthy volunteers (8 cases for dermal tissue; 6 females, 2 males , average age 48 and 8 cases for buccal gingival tissue; 6 females, 2 males, average age 43) whose informed consent was obtained according to a protocol approved by the ethics committee of Nagoya University Hospital. After enzymatic digestion, tissues were cultured in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal bovine serum at 37°C in the presence of 5% CO2 for about 4 weeks as reported previously. Total mRNAs were extracted from cells between passages 4-5 by Trizol reagent (Invitrogen, Carlsbad, CA, USA) and were applied to Human Focus Arrays (Affymetrix, Santa Clara, CA, USA) for microarray analysis according to the manufacturer's protocol (http://www.affymetrix.com/support/technical/manuals.affx). The gene expression data were analyzed by Arrayassist (Stratagene, La Jolla, CA, USA). Briefly, 8,500 probes on the array, normalization and scaling (MAS5), flag-positive gene selection, unpaired t-test, and CV selection (<20) resulted in 5,284 genes to analyze. GO (Gene ontology) analysis was performed using the software default settings to find the gene group related to the same category of biological function by searching common key terms that were reported for each gene.

Project description:Pericytes derived from skin dermis can substantially enhance the short-term tissue-regenerative capacity of human epidermal cells already committed to differentiation; they also display both phenotypic and functional properties of mesenchymal stem cells. In this microarray analysis, we compared the gene expression profile of dermal pericytes to that of the remaining dermal cells of neonatal human foreskin. Experiment Overall Design: Human neonatal foreskin was digested overnight in dispase II at 4°C to separate the epidermis from the dermis. Subsequently the dermis was digested for 1-2 hours at 37°C in a mixed dispase and collagenase solution and then fractionated into two populations, i.e. pericytes (HD-1bri) and the remaining dermal cells (HD-1dim), on the basis of differential VLA-1 expression using fluorescence-activated cell sorting. Total RNA from 15,000 cells of each population was extracted from 4 independent replicate sorts. mRNAs were amplified using a T7-primer-based-2-round linear RNA amplification protocol (GeneChip Two-Cycle cDNA synthesis kit). Fragmented and biotin-labelled cRNA from each individual sample was hybridised to Affymetrix HG-U133 plus 2.0 arrays and scanned on a Affymetrix GeneChip scanner. Probe intensities were RMA normalized and log2-transformed expression values were compared using moderated t statistics to quantify differences between individual samples.

Project description:Hair follicle formation depends on reciprocal epidermal-dermal interactions and occurs during skin development, but not in adult life. This suggests that the properties of dermal fibroblasts change during postnatal development. To examine this, we used a PdgfraEGFP mouse line to isolate GFP-positive fibroblasts from neonatal skin, adult telogen and anagen skin and adult skin in which ectopic hair follicles had been induced (EF skin) by transgenic epidermal activation of beta-catenin. We also isolated epidermal cells from each mouse. The gene expression profile of EF epidermis was most similar to that of anagen epidermis, consistent with activation of beta-catenin signalling. In contrast, adult dermis with ectopic hair follicles more closely resembled neonatal dermis than adult telogen or anagen dermis. In particular, genes associated with mitosis were upregulated and extracellular matrix-associated genes were downregulated in neonatal and EF fibroblasts. We confirmed that sustained epidermal beta-catenin activation stimulated fibroblasts to proliferate to reach the high cell density of neonatal skin. In addition, the extracellular matrix was comprehensively remodelled, with mature collagen being replaced by collagen subtypes normally present only in developing skin. The changes in proliferation and extracellular matrix composition originated from a specific subpopulation of fibroblasts located beneath the sebaceous gland. Our results show that adult dermis is an unexpectedly plastic tissue that can be reprogrammed to acquire the molecular, cellular and structural characteristics of neonatal dermis in response to cues from the overlying epidermis. We have isolated the following populations of cells from mouse back skin by flow cytometry: 1A) GFP+ WT neonatal dermal fibroblasts, 1B) ItgA6+ WT neonatal epidermal keratinocytes, 2A) GFP+ WT telogen dermal fibroblasts, 2B) ItgA6+ WT telogen epidermal keratinocytes, 3A) GFP+ D2 transient activation (anagen) dermal fibroblasts, 3B) ItgA6+ D2 transient activation (anagen) epidermal keratinocytes, 4A) GFP+ D2 sustained activation (ectopic follicles) dermal fibroblasts, 4B) ItgA6+ D2 sustained activation (ectopic follicles) epidermal keratinocytes
