Stem cells are autologous http://www.cheapsuperstarwomenssale.com/ , coming from your own body or allergenic, coming from another person who donates
them. Stem cells are unique in their ability to divide and regenerate themselves
and in their ability to remain specialized or unspecialized in the tasks of the
human body. Stem cell therapy for conditions characterized by myocyte loss in
myocardial infarction and heart failure is intuitively appealing. Stem cells
from various sources, including heart itself in preclinical and animal studies,
have shown the potential to improve the function of ventricular muscle after
ischemic injury. Stem cell-based therapy became a realistic option to replace
damaged heart muscles due to series of experimental findings of myocyte turnover
in mammalian heart. Stem cells are primitive Cheap Adidas Superstar China , undifferentiated; undefined pluripotent multiline age cells that retain the ability to renew themselves through mitotic cell division and
can divide and create a cell more differentiated than it. Stem cells have the
ability to differentiate into specific cell types. The 2 defining
characteristics of a stem cell are perpetual self-renewal and the ability to
differentiate into a specialized adult cell type. There are 2 major classes of
stem cells: pluripotent cells which can become any cell in the adult body and
multipotent cells which are restricted to becoming a more limited population of
cells. Pluripotent stem cells being used in research today mainly come from
embryos, hence the name embryonic stem cells. Preimplantation embryos a few days
old contain only 10% to 15% pluripotent cells in the "inner cell mass".
Multipotent stem cells may be a viable option for clinical use. These cells have
the plasticity to become all progenitor cells for a particular germ layer or can
be restricted to become only 1 or 2 specialized cell types of a particular
tissue. Multipotent cells have also been used as the starting point for cell
therapy, again with cocktails of growth factors andor chemicals to induce
differentiation toward a specific, desired lineage. Pluripotent stem cells have
not yet been used therapeutically in human beings because many of the early
animal studies resulted in the undesirable formation of unusual solid tumors
called teratomas. Stem cell use is exciting and holds great promise for treating
and perhaps one day curing many diseases.
A stem cell therapy is a treatment that replaces dysfunctional or diseased tissues with stem cells. Stem
cells are already used in cell therapies for treatment of some cancer types but
this use is still small in the scheme of diseases affecting humans. Stem cell
use is exciting and holds great promise for treating and perhaps one day curing
many diseases. Their importance ranges from an understanding of the principles
behind human development to the cell based therapies addressing those aspects
that go awry during development and lead to disease. The stem cells have the
impending to treat a massive variety of the diseases and conditions which swarm
million people throughout the world. The promise of stem cell therapy involves
targeted transplantation of these tot potent Cheap Adidas Superstar Sale , healthy stem cells to diseased organs and tissues. Replacement of degenerating neurons by healthy neurons in a Parkinson's patient
can dramatically enhance quality of life and prolong life span. Stem cells are,
very basically, cells that have the potential to become any number of other
cells. There are two broad categories of stem cells: embryonic stem cells
derived from the developing embryo, and adult stem cells derived from more
highly specified tissues. The quantity of cells and time of infusion should be
carefully considered to avoid coronary flow impairment and myocardial cell
necrosis. This technique may not be suitable for certain types of larger stem
cells Cheap Authentic Adidas Superstar , such as skeletal myoblasts which may be prone to embolization.
