What are stem cells and how do they work? In this video, we explain stem cells in simple words — from how 330 million new cells replace old ones in your body every day, to the four types of stem cells (totipotent, pluripotent, multipotent, unipotent), how differentiation works, gene expression, and the Nobel Prize-winning discovery of induced pluripotent stem cells (iPSCs) that reversed what scientists thought was impossible.
Whether you're a biology student, curious about regenerative medicine, or fascinated by how a single zygote becomes 30 trillion cells, this beginner-friendly animated explainer covers everything.
