Outline an experimental design that would enable you to explore the influence of EVs on your chosen epigenetic mark. Include a hypothesis, methodology, what you will quantify, and how will you interpret the data in 800 words
. Hypothesis: EVs derived from aged cells can influence the epigenetic landscape of stem cells, leading to alterations in specific epigenetic marks. Methodology: To investigate this hypothesis, we will design an experiment in which EVs derived from aged cells will be incubated with stem cell populations in vitro. We will use fluorescently labeled EVs from aged cell samples in order to track their uptake and distribution within the stem cell population. Additionally, we will use a combination of chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) and RNA sequencing (RNA-seq) to characterize the changes in epigenetic marks and gene expression, respectively. Quantification: To assess the impact of the EVs on the epigenetic marks, we will measure the enrichment of different chromatin marks (H3K4me3, H3K27me3, H3K36me3, etc.) and transcription factor binding (TFs) at the target gene promoters relative to the control. To quantify the changes in gene expression, we will measure the mRNA levels of target genes using qPCR. Data Interpretation: We will assess the impact of aged cell EVs on the epigenetic landscape of stem cells by comparing the epigenetic marks and gene expression levels between the experimental and control groups. If the EVs are capable of influencing the epigenetic landscape, we expect to see an increase in certain epigenetic marks and changes in gene expression. If this is observed, we will be able to conclude that EVs derived from aged cells can be used to modify the epigenetic landscape of stem cells. Since this experiment investigates changes in the stem cell epigenetic landscape caused by EVs, it is important that we assess the potential effects of the EVs on other genes and non-specific interactions. To this end, we will use a control where EVs are incubated with stem cells that have been treated with a vehicle control. We will compare the results from this control with the experimental results, to ensure that the changes observed are specific to the EVs and not caused by other sources. Overall, our proposed experiment will enable us to explore the influence of EVs derived from aged cells on the epigenetic landscape of stem cells. If our hypothesis is correct, we expect to observe changes in epigenetic marks and gene expression that are specific to the EVs and not caused by other sources. This data will provide evidence of the ability of EVs from aged
