STEM CELL
Introduction to Stem Cells: Stem cells are undifferentiated cells present in embryonic, fetal, and adult stages. They can give rise to various cell types in the body, having clonogenic and self-renewing capabilities. These cells are unspecialized, have a high proliferation rate, and possess plasticity, meaning they can transform into different cell lineages. Stem cells are part of all organs in the body. Characteristics of Stem Cells: Self-Renewal : Stem cells can extensively proliferate, maintaining their population throughout life. Clonality : Usually, stem cells arise from a single cell. Potency : This refers to the ability to differentiate into different cell types. Stem cells can either produce a copy of themselves (renewal) or differentiate into specialized cells through a multi-step process, each step leading to a more specialized cell. Self-Renewal and Differentiation: Self-renewal involves the division of stem cells to maintain their undifferentiated state, requiring contr
