# What are the main types of stem cells?

## Short answer

There are three main types. Embryonic stem cells come from early embryos and can form all body cell types. Adult, or tissue-specific, stem cells are found in places such as bone marrow and blood, and usually produce only a limited family of cells. Induced pluripotent stem cells are mature cells reprogrammed in the lab to behave like embryonic stem cells. Umbilical cord blood stem cells are a further, blood-forming source.

## Answer

Human embryonic stem cell lines were first reported in 1998 [3]. Reprogramming of mouse cells into iPSCs was reported in 2006 [4].

### Stem cells in cosmetic surgery

In cosmetic surgery, "stem cell" procedures almost always use [adipose-derived stem cells](/entity/adipose-derived-stem-cell). The stromal vascular fraction (SVF), which contains them, is separated from liposuctioned fat and mixed into the fat being grafted, as in [stem cell breast augmentation](/entity/stem-cell-breast-augmentation) and [stem cell fat grafting](/entity/stem-cell-fat-grafting).
