because if they weren't frozen, they would deteriorate - accumulate mutations, get damaged by their own waste metabolites etc. In frozen state, they do not metabolize or grow, thus they are free of these negative effects.
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
Most scientists agree that frozen embryos created through in vitro fertilization should be used to create stem cells, although many people are against it because of their religious views.
There are 2 type of stem cells * embryonic stem cells * and adult stem cells fetal stem cells are grouped into the adult stem cell category
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
Pluripotent stem cells.

stem cells
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
They are called stem cells.
Stem cells are cells that are able to divide continuously without specializing. These kind of cells are undifferentiated biological cells.
There are three different types of tissue stem cells in the body. They include the tissue stem cells also known as adult stem cells, embryonic stem cells, and induced pluripotent stem cells.
Multipotent stem cells
Multipotent stem cells
What kind(s) of cells can develop from unipotent stem cells
Pluripotent stem cells.
