There are several types of stem cells that can be used for different purposes.
Embryonic stem cells (ESC) are cells that can be transformed into cells of any lineage and are derived from the inner cells of the blastocyst a few days after egg fertilisation.
Tissue-specific stem cells can be found all over the body, and with the right intervention and environmental signals, they can differentiate into numerous lineages to generate cartilage, bone, muscle, and adipose tissue in vitro and in vivo.
Hematopoietic stem cells (HSCs) are multipotent cells found in the bone marrow that are responsible for the lifelong generation of all types of blood cells.
NSCs are a type of ectodermal progenitor cell that can differentiate into committed neural subtypes such as neurons, astrocytes, and oligodendrocytes.
Mesenchymal stem cells are multipotent adult stem cells found in a variety of organs such as the umbilical cord, bone marrow, and adipose tissue.
Bone marrow (a spongy tissue found in the centre of some bones) produces stem cells, which can differentiate into several types of blood cells.
Cancer stem cells (CSCs) are a type of tumour cell that can initiate new tumours and induce relapses. CSCs are derived from differentiated cells or adult tissue resident stem cells at the time of tumour development.
Adult stem cells are undifferentiated cells that live in a tissue or organ among specialised cells. They have the potential to regenerate and differentiate into numerous types of cells
