In the last few years several technologies are being developed for eventually
repairing or replacing damaged or injured tissues and even organs. Some of these emerging technologies include the design
and development of new biomaterials, the optimization of nano- and micro-technologies for drug and cell delivery,
the use of autologous proteins or the application of stem cells as therapeutics. Thus, several types of stem cells, e.g. ESCs,
iPSCs, MSCs, CD133+ stem cells are being evaluated for tissue regeneration purposes. The present review describes
some of these emerging technologies and discusses their potential benefits and challenges.
