Final answer:
Embryonic stem cells and adult stem cells, including cells from the umbilical cord and baby teeth, are two sources of stem cells used for therapeutic treatments. These cells are essential for regenerative medicine and cell-based therapy to treat various diseases.
Step-by-step explanation:
Two sources of stem cells that can be used in therapeutic treatment are embryonic stem cells and adult stem cells. Embryonic stem cells are derived from embryos and are pluripotent, which means they can give rise to nearly any cell type of the body. Adult stem cells, such as hematopoietic stem cells from bone marrow, are multipotent and can generate a range of cell types within a certain tissue or organ.
Cells from the umbilical cord and from deciduous teeth (baby teeth) are also sources of multipotent stem cells banked by parents for potential future medical use. In addition to these sourced cells, technology and research have enabled the development of induced pluripotent stem cells (iPSCs) from adult stem cells, which function similarly to embryonic stem cells.
These stem cells are pivotal in cell-based therapy which aims to repair or replace damaged or destroyed cells or tissues in conditions such as diabetes or heart disease.
