How unspecialized cells transform into the complex building blocks of life

Stem cells and differentiation | From cells to organisms | High school biology | Khan Academy · 6:44 · Video: Khan Academy · Watch at the source

In short: This video explains the fundamental process of stem cell differentiation. You will learn how these versatile cells divide and specialize to create the diverse array of cells required to build a complex organism.

The video explores the concept of potency, which measures a stem cell's capacity to transform into specialized cell types. It distinguishes between three primary levels of potential: totipotent, pluripotent, and multipotent cells.

Beyond specialization, the video covers self-renewal, the ability of stem cells to undergo multiple divisions while maintaining their unspecialized state. Understanding these mechanisms is essential for grasping how a single cell can eventually develop into an entire organism.
