Definition
Stem cells are undifferentiated cells capable of self-renewal and differentiation into various cell types; embryonic stem cells are derived from early-stage embryos and can differentiate into any cell type, while adult stem cells are found in specific tissues and typically give rise to a limited range of cell types related to their tissue of origin.
Summary
Stem cells are remarkable cells that have the ability to develop into various cell types, making them essential for growth, development, and healing. They are categorized into embryonic stem cells, which can become any cell type, and adult stem cells, which are more specialized. Understanding these differences is crucial for their application in medicine and research. The potential of stem cells in regenerative medicine is vast, offering hope for treating diseases and injuries. However, ethical considerations surrounding their use, particularly embryonic stem cells, continue to spark debate. As research progresses, the future of stem cell therapy holds promise for innovative treatments and a deeper understanding of human biology.
