Research Value of Stem Cells 4b
Stem Cell Therapies
Tissue stem cells are routinely used in
bone marrow transplantation
to treat
blood cancers
such as leukaemia.
Uses of Stem Cells
Regeneration of damaged skins (skin graft)- a small
sample of skin taken
using enzymes to isolate and loosen stem cells to
create a suspension of new stem cells
that can then be
cultured and then sprayed over the damaged skin
to
bring about regeneration.
Bone Marrow Transplant
- tissue stem cells
in bone
and blood are used to
treat cancers of the blood.
Corneal repair - by
collecting and growing a patient's own stem cells
located on the edge of the cornea and
grafting these onto the cornea
Research value of stem cells
Given
optimal culture conditions
and
provided with certain growth factors
human stem cells can be grown rapidly.
Without these growth factors
the stem cells will begin to
differentiate
.
Future potential stem cell therapies
-As a source of temporary skin to treat burn victims (while a patient is waiting for grafts of their own skin to develop).
-To treat degenerative conditions such as Parkinson's disease and Alzheimer’s disease.
The use of embryonic stem cells:
-To treat neurological disorders such as multiple
sclerosis
Regulation of the use of stems cells
This is to ensure that the quality of the stem cells used, and the safety of procedures are of the highest order
Stem cell research is carefully regulated in the UK by laws, and licences must be obtained before research involving stem cells can be carried out
UK laws:
Human Fertilisation and Embryology Act
Human Reproductive Cloning Act
