Germinal cells can become embryonic stemcells: study
Dec 2, 2007
WASHINGTON (AFP) — Primordial germinal cells, which are precursors to
spermatozoids, apparently have the capacity of turning into embryonic
stem cells, according to a study made public Sunday.
Embryonic stem cells can be converted into different types of cells
and subsequently tissues, thus offering the hope to fight a number of
diseases that have thus far remained incurable.
Researcher from the Georgetown school of medicine and a Washington-
based regional transplant consortium known as WRTC have obtained
these primordial germinal cells shortly after donors' deaths.
These cells knows as CGPM were separated using a process that
involves enzymes.
When the CGPM cells were placed in human embryonic stemcell cultures,
they formed colonies that had characteristics similar to stem cells,
according to Doctors Martin Dym and Nady Golestaneh, the main authors
of the study presented here at a conference of the American Society
for Cell Biology.
When these colonies of stem cells were allowed to grow and multiply,
they displayed characteristics similar to somite entoblast and
ectoblast cells found in an embryo.
This has led the researchers to believe that primordial germinal
cells have a great potential for organ regeneration therapies.
Doctor Dym pointed out that one could imagine a day when men could be
cured from various diseases through testicular biopsy.
