Mesenchymal Stem Cells Are Stromal Cells, Which Can Self-Regenerate and Exhibit Multi-Lineage Differentiation
Mesenchymal Stem Cells |
Mesenchymal stem cells are often isolated from cord
tissue and expand into higher numbers for transplantation. Unlike embryonic
stem cells, mesenchymal stem cells are not rejected by the immune system and
increase the body's natural healing ability. They have potent anti-inflammatory
and immunosuppressive properties and can help treat many autoimmune diseases.
In fact, mesenchymal stem cells have been used in the treatment of several
autoimmune diseases, including rheumatoid arthritis and lupus.
In vitro studies of mesenchymal stem cells in mice
showed that the cells inhibited tumor growth, reduced vascular permeability,
and decreased AKT activity. These results indicate that mesenchymal stem cells
can be used to treat cancer. The cells can be transplanted intravenously. They
inhibit tumor growth in a mouse model by inhibiting the activity of AKT. But
further studies are needed to better understand how MSCs can be used to treat a
wide variety of conditions.
The potency of mesenchymal stem cells has largely been
linked to their age. Younger stem cells tend to reproduce faster and
differentiate into more diverse cell types, such as neural cells. But despite
the many benefits, research challenges have been hindering their use in
clinical settings. One of these challenges is obtaining enough mesenchymal stem
cells. The other problem is that MSCs can lose their potency as they undergo
sub-culturing and higher passages. The shortening of the telomeres in human
BM-MSCs is a major cause of senescence. The same applies to MSCs derived from
adipose tissue.
Because Mesenchymal
Stem Cells are pluripotent and able to divide into any mature
cell type, their therapeutic potential is vast. While there are some concerns
regarding the role of MSCs in cancer, newer studies have demonstrated promising
results. The use of MSCs in cancer therapy is a major step forward, but there
is still much more work to be done before we can be confident in their
therapeutic potential. If successful, this therapy may revolutionize cancer
treatment.
Mesenchymal stem cells are a form of bone marrow
precursors. They can differentiate into different cell lineages from unrelated
germline origins. Physiological stromal niches also contain mesenchymal stem
cells, and the presence of mesenchymal stem cells supports the homeostasis of
hematopoietic stem cells. And these cells are also subject to natural killer
cells. As such, they are an essential source of bone and cartilage.
The clinical uses of mesenchymal stem cells are likely
to increase in the coming years. The availability of a large number of MSCs in
an 'off-the-shelf' form is necessary for clinical applications. This requires
proper in vitro mesenchymal stem cell expansion and cryopreservation. But these
processes provide unique opportunities to explore their uses. So, it is crucial
to ensure safety when cryopreserving and banking hMSCs.
Researchers have reported that human UCB-mesenchymal
stem cells are capable of enhancing the activity of the neural crest, as well
as improving neuronal survivability in a mouse model of Alzheimer's disease.
Similarly, dental UCB-MSCs can successfully differentiate into neuronal cells.
Ultimately, mesenchymal stem cells are an excellent way to transform
regenerative cell therapies.
As a cell source for regenerative medicine,
mesenchymal stem cells can differentiate into specific cell types, such as
chondrocytes, adipocytes, and bone marrow stromal cells. In vivo, however,
cardiomyocyte differentiation from MSCs is difficult and effective only when
stem cells are young. Despite their potential for therapeutic benefits, this
therapy has been used to treat heart failure secondary to left ventricular
injury in rodent models.
