What best describes totipotent stem cells?

Totipotent stem cells are unique because they possess the ability to develop into any cell type in the body, as well as the extraembryonic tissues that support development in early stages. This means that they can give rise to a complete organism, as well as all the specialized cells and structures necessary for a fully functional body. This characteristic differentiates them from other types of stem cells, such as pluripotent or multipotent cells, which have more limited potential in terms of differentiation. Therefore, the description that they can develop into any cell type in the body accurately captures the full potential of totipotent stem cells.
