Stem Cell Therapy
Stem
Cell Therapy
A stem cell is a
cell with the unique ability to develop into specialized cell types in the
body. In the future they may be used to replace cells and tissues
that have been damaged or lost due to disease.
Embryonic
stem cells
Embryonic
stem cells are obtained from the inner cell mass of the blastocyst, a
mainly hollow ball of cells that, in the human, forms three to five days after
an egg cell is fertilized by a sperm. In normal development, the cells inside
the inner cell mass will give rise to the more specialized cells that give rise
to the entire body—all of our tissues and organs. However, when scientists
extract the inner cell mass and grow these cells in special laboratory
conditions, they retain the properties of embryonic stem cells. Embryonic
stem cells are pluripotent, meaning they can give rise to every cell type
in the fully formed body, but not the placenta and umbilical cord. These cells
are incredibly valuable because they provide a renewable resource for studying
normal development and disease, and for testing drugs and other therapies.
Human embryonic stem cells have been derived primarily from blastocysts created
by in vitro fertilization (IVF) for assisted reproduction that were no longer
needed.
Tissue-specific
stem cells
Tissue-specific stem cells (also referred
to as somatic or adult stem cells) are more specialized
than embryonic stem cells. Typically, these stem cells can generate different
cell types for the specific tissue or organ in which they live. For example,
blood-forming (or hematopoietic) stem cells in the bone marrow can give
rise to red blood cells, white blood cells and platelets. However, blood-forming
stem cells don’t generate liver or lung or brain cells, and stem cells in other
tissues and organs don’t generate red or white blood cells or platelets. Some
tissues and organs within your body contain small caches of tissue-specific
stem cells whose job it is to replace cells from that tissue that are lost in
normal day-to-day living or in injury, such as those in your skin, blood, and
the lining of your gut.
Induced
pluripotent stem cells ( iPS)
Induced pluripotent stem (iPS)
cells are cells that have been engineered in the lab by converting
tissue-specific cells, such as skin cells, into cells that behave like
embryonic stem cells. IPS cells are critical tools to help scientists learn
more about normal development and disease onset and progression, and they are
also useful for developing and testing new drugs and therapies. While iPS cells
share many of the same characteristics of embryonic stem cells, including the
ability to give rise to all the cell types in the body, they aren’t exactly the
same. Scientists are exploring what these differences are and what they mean.
For one thing, the first iPS cells were produced by using viruses to insert
extra copies of genes into tissue-specific cells. Researchers are experimenting
with many alternative ways to create iPS cells so that they can ultimately be
used as a source of cells or tissues for medical treatments.
Mesenchymal
Stem Cells ( MSC)
Mesenchymal stem cells (MSCs) are adult
stem cells traditionally found in the bone marrow. However, mesenchymal stem
cells can also be isolated from other tissues including cord blood, peripheral
blood, adipose tissue and other tissues. MSCs typicallly differentiate to form
adipocytes, cartilage, bone, tendons, muscle, and skin (mesodermal tissues)
.
Morphologically, mesenchymal stem cells
have long thin cell bodies (spindle-shaped) with a large nucleus. As with other
stem cell types, MSCs have a high capacity for self renewal while maintaining
multipotency. Thus, mesenchymal stem cells have enormous therapeutic potential
for tissue repair. In the last few years the immunomodulatory and
neuoroprotective properties of MSC were discovered. These discoveries make MSC
good candidate to act as therapeutic agents in diseases such Multiple
Sclerosis and other neurological diseases.
Ongoing or completed numerous research
involving mesenchymal Stem Cells (MSC), represent promising alternatives for
conventional treatments for various non-cancerous medical disorders. ECCT
offers Stem Cell Transplantation for patients with various cancerous
diseases such as Leukemia, Hodgkin and Non– Hodgkin lymphoma, Multiple
Myeloma, Myelodysplastic Syndromes, Aplastic Anemia. ECCT is highly specialized
in Mesenchymal Stem Cell therapy and can offer promising therapeutic
alternatives for diseases such as Multiple Sclerosis and Amytotrphic Lateral
Sclerosis (ALS) which are neurodegenrative diseases.
