So what does some of that mumbo-jumbo technical jargon really mean? Learn their meanings by browsing our online glossary.Adult stem cell An unspecialized stem cell found in
a specific tissue that can renew itself
and differentiate (with limitations) to
develop into any of the cell types of
the tissue from which it originated. Allogenic transplantation Cell, tissue or organ transplants
from one member of a species to a
genetically different member of the
same species. Autologous transplantation Cell, tissue or organ transplants from
one individual back into the same
individual. Such transplants are often
performed with blood products or bone
marrow and don’t induce an immune
response and are not rejected. Blastocyst A very early stage embryo, prior to
implantation at around 5-6 days post
fertilization. A blastocyst is a cluster of
approximately 150 cells, the size of a
pinhead, containing a cavity. The centre
is filled with fluid and surrounded by
a cluster of cells called the inner cell
mass (from which embryonic stem cells
are derived, which give rise to all the
organs and tissues of a future embryo
and fetus) and an outer layer of cells
called the trophoblast (that forms the
fetal portion of the placenta). Cell culture The growth of cells in vitro in an
artificial solution that contain nutrients
and growth factors. Cell division The continuous process by which one
cell divides into two cells, thereby
increasing the cell population. Cell-based therapies A treatment that involves stem cells
being induced to differentiate, or
develop, into specific cell types
required to repair or rebuilt depleted
cell populations or tissues. |
