<p>I have single cell data which I have analysed for differential expression. In my experiment,  I subjected two groups of mice (a control and a treatment group) to treatment that will lead to the proliferation of my cells of interest in the treated mice. Other scientists have said that the increase of cell numbers caused by this treatment results from increased recruitment from precursor cells from the bone marrow while other scientists argue that the increase in cell number is due to local proliferation.  </p>

<p>I wish to address this question computationally, based on my single cell rna seq data using R or any other method. I have googled but I can find no suitable tool. Does it suffice to test the expression of known cell migration markers, produce a migration score  and judge based on the migration scores of my proliferating cells?</p>

<p>If not, I will be very grateful for suggestion of a computational tool, method or package that can help me address this question even indirectly.</p>

<p>Thank you in advance.</p>

Do you have single cell data of both regions, bone marrow and local region? How good are your cell migration markers?

@Irls Thanks a lot for your response. Yes I do have but do you please have a hint on now to proceed from here?

Is there a computational method/method/way to predict if a cell population in a tissue immigrated or is enriched locally?

This may not be a viable answer for all experimental contexts, but you can compare expression profiles of individual cells against datasets that contain known reference cell types (migratory and not). We have recently published a web-based tool called [CIPR](https://aekiz.shinyapps.io/CIPR/) (cluster identity predictor) that helps with cluster annotations in scRNAseq experiments. There are various reference datasets available, but you can also provide a custom reference by preparing data from databases like [GEO](https://www.ncbi.nlm.nih.gov/geo/browse/).

You can read the [manuscript](https://bmcbioinformatics.biomedcentral.com/articles/10.1186/s12859-020-3538-2) for more information about how the algorithm works, but in a nutshell, it compares differentially expressed genes or global expression patterns within your data to known reference datasets and creates quick visual outputs.
