**How many types of stem cells are there? ** Today, researchers classify three types of stem cells (SC). The two types of SC ⬆️ are ‘natural’: 1️⃣**Embryonic SC** supply new cells for an embryo as it grows and develops into a baby. Being __‘pluripotent’__, they can change into any cell in the body. 2️⃣ **Adult SC** replace old or damaged cells as an organism grows. Being __‘multipotent’__, they can only change into some cells in the body – not all cell types, because they have already started to specialize, so can only develop further into a specific type of cell. The third type ⬆️ is ‘artificial’. 3️⃣ **Induced pluripotent SC** (or ‘iPS cells’) are made in the laboratory. Normal adult cells (often skin cells) can be reprogrammed to become stem cells. This is called ‘inducing’ the stem cells. iPS cells are pluripotent so can, theoretically, like Embryonic SC, develop into any cell type. ℹ️ In medicine, stem cells are used to replace cells and tissues that have been damaged or lost due to diseases.
