Since stem cells were first discovered, researchers have identified distinct stem cell populations in different organs and with various functions, converging on the unique abilities of self-renewal and differentiation toward diverse cell types. These abilities make stem cells an incredibly promising tool in therapeutics and have turned stem cell biology into a fast-evolving field. Here, stem cell biologists express their view on the most striking advances and current challenges in their field.
