This characteristic allows them to maintain tissue homeostasis throughout a person's life.
The consideration of using stem cells in practice leads to a variety of advantages and challenges. While embryonic stem cells may provide broader opportunities for tissue regeneration, adult stem cells tend to have lower immunogenicity and ethical concerns.
Mechanisms of Differentiation
Mechanisms of differentiation describe how stem cells transform into specific cell types. This process is orchestrated by a multitude of factors, including internal signals (like gene expression) and external influences (such as the surrounding environment).
A key feature of these mechanisms is the role of signaling pathways and transcription factors in guiding stem cell fate. Improved understanding of these pathways is a promising avenue for developing therapies targeting diseases caused by cell dysfunction. For example, manipulating differentiation pathways could assist in generating insulin-producing cells for diabetes treatment.
Nevertheless, harnessing these differentiation mechanisms is not without its drawbacks. Variability in differentiation outcomes can lead to inconsistent results in clinical applications. Moreover, the potential for tumorigenesis — uncontrolled cell proliferation — remains a significant risk.
