Detailed explanation-1: -In a stem cell, DNA (gold) is wrapped loosely around histone proteins (blue). In a differentiated cell, segments of DNA that are not required for the cell’s specialized function are shut down and wrapped tightly around histone proteins.
Detailed explanation-2: -A differentiated cell means a cell that has changed in form and matured from being generalized into being more specific in terms of function. The term undifferentiated is used to describe a cell (or a tissue) that has not yet acquired a special structure and function.
Detailed explanation-3: -The stem cells can only differentiate into a few different cell types. Somatic stem cells, for example, are found in the bone marrow and can only become red blood cells. Undifferentiated cells are cells that have not yet developed into a specific cell variety.
Detailed explanation-4: -Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells become either new stem cells or specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells or bone cells.
