Demonstrations of transdifferentiation, converting one cell type directly into another, have been picking up of late. Like research into creating stem cells, it has the potential to enable a new generation of regenerative therapies, or make existing therapies more effective and less costly. Here is an example of the present state of research: "For the past decade, researchers have tried to reprogram the identity of all kinds of cell types. Heart cells are one of the most sought-after cells in regenerative medicine because researchers anticipate that they may help to repair injured hearts by replacing lost tissue. Now, [researchers] are the first to demonstrate the direct conversion of a non-heart cell type into a heart cell by RNA transfer.
