NEET BIOLOGY

Detailed explanation-1: -Stem cell differentiation involves the changing of a cell to a more specialized cell type, involving a switch from proliferation to specialization. This involves a succession of alterations in cell morphology, membrane potential, metabolic activity and responsiveness to certain signals.

Detailed explanation-2: -Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.

Detailed explanation-3: -“We found that the stem cell-specific protein OCT4 primes certain genes that, when activated, cause the cell to differentiate, or become more specialized, ” said Laszlo Nagy, M.D., Ph.

Detailed explanation-4: -Cells undergo a process called differential gene expression. This process allows cells to become specialized, as their structure determines their function. The process begins when a stimulus acts on an unspecialized cell (a cell that has the potential to become any cell in the body-multipotent stem cells).
