10. Mesenchymal stem cells
— Adult stem cells, multipotent
— Found in bone marrow, fat etc
— Produce e.g. bone, cartilage, fat
— Immunosupressive
— Graft-versus-host
— Cell therapy:
— Bone
— Cartilage
— Brain diseases
— Heart failure
14. Pluripotent stem cells
Embryonic stem cell vs iPS cells
Blastocyct
Differentiated cell
Patient sample
e.g. skin, blood
Inner cell mass
Pluripotent
stem cell
iPS cell
Embryonic stem
cell
Differentiate into any cell
Genotype and disease-spesific cells!
