Stem cells can turn into heart cells, skin cells can mutate to cancer cells; even cells of the same tissue type exhibit small heterogeneities. Scientists use single-cell analysis to investigate these heterogeneities. But ...

The Wnt/β-catenin signaling pathway and microRNA 335 are instrumental in helping form differentiated progenitor cells from stem cells. These are organized in germ layers and are thus the origin of different tissue types, ...
