Unveiling Aging Heterogeneities in Human Dermal Fibroblasts via Nanosensor Chemical Cytometry

Project description:To investigate aging heterogeneity in tissue-regeneration cells, we conducted RNA-seq analysis of human dermal fibroblasts (hDFs) at two distinct aging stages: passage 5 (p5) and passage 15 (p15). hDFs were cultured under standard conditions, and total RNA was extracted for sequencing. Transcriptomic profiling was performed to identify differentially expressed genes associated with cellular aging. This RNA-seq dataset was used to validate the phenotypic changes observed via a label-free, nondestructive single-cell analytics platform called nanosensor chemical cytometry (NCC). The integrated analysis revealed that transcriptomic aging signatures correspond with aging phenotypes such as changes in cell size, shape, refractive index, and H2O2 efflux. This dataset provides insight into the molecular mechanisms underlying cell aging and supports the development of predictive models for therapeutic performance in regenerative medicine.

Comparative gene expression analysis of 2 subpopulations of dermal papilla cells.

Project description:Different types of hair follicles can be found in the skin of mice. It is believed that the signals that control hair follicle differentiation arise from cells in a structure called the dermal papilla. Understanding the nature of those signals is of interest for the biology of the normal tissue. We have developed a technique for isolation of dermal cells by enzymatic digestion of intact skin. We have identified two subpopulations of cells that can be separated by FACS. The Sox2-positive CD133-positive cells are found exclusively in the dermal papillae of guard/awl/auchene hairs, while Sox2-negative, CD133-positive cells are found in the other hair follicle types. We compared these populations with unfractionated dermal cells. We isolated the following 3 populations of cells from the back skin of neonatal mice (P2) by Flow Cytometry: 1) GFP-CD133- Total dermal cells 2) GFP-CD133+ Dermal Papilla cells 3) GFP+CD133+ Dermal Papilla cells The yield is approximately 50,000 cells of each population.

Chemical reprogramming of melanocytes to skeletal muscle cells

Project description:We identify a combination of small molecules to be able to transdifferentiate dermal cells to muscle cells. To characterize the cellular diversity of the neonatal dermal we performed scRNA-seq on mononuclear cell suspensions obtained from the neonatal dermal. Following normalization and quality control of scRNA-seq data, we captured 40537 cells with an average of 5755 genes expressed per cell. We charted the entire course of skin-to-muscle chemical reprogramming by single cell RNA-sequencing to determine the source cells in CD73- cells from skin with the potential to be transdifferentiated to muscle cells .We found that melanocytes could be chemically reprogrammed to myogenic lineage cells.

Gene expression profiling of adult hair follicle dermal stem cells and progeny, dermal sheath and dermal papilla cells

Project description:Here we have developed a novel FACS strategy to prospectively isolate hair follicle dermal stem cells, dermal sheath and dermal papilla cells from adult skin initiating synchronous hair follicle regeneration and identified Hic1 as a marker of hfDSCs and Rspondins as stimulators of hfDSCs and epithelial cells, and subsequently hair follicle regeneration
