Advances in microfluidic technologies enabled us to barcode single cells in lipid droplets and to resolve genomes of individual cells from a sequencing mixture (e.g, 10X Genomics). By using Single cell RNA sequencing (scRNA-seq) we can discover rare cell populations and genes that are specifically acting in those. Potential is high and the list of publications growing daily.
If you are a scientist in a biotech exploring novel targets those might be a great source to gather specific information.
