of stem cells of adipose origin and preferential expression and interplay of pro-chondrogenic molecules, either through some genetic alteration or environmental factors, are responsible for chondrogenesis in these lesions (2).

of embryonic stem cells," Development, vol.
Exposure of cultured mouse embryonic stem cells to REACF was found to afford expression of pluripotentiality
and high-throughput of commitment towards myocardial, neuronal and skeletal muscle differentiation (3,4).
Migrating germ cells in the retroperitoneum of a 12-week fetus are positive for pluripotentiality
markers OCT3/4 (A) and SALL4 (B) (original magnifications X200 [A and B]).
They suggested that all periosteum has the pluripotentiality
to give rise to cartilaginous as well as osseous cells.
Although hES and hiPS cells have similar pluripotentiality
, they are not identical.
These anti-statists may refuse to define the cultural content of libertopia because they believe deeply in the pluripotentiality
of freedom--that freedom can mean the freedom to be a Mormon housewife as well as to be a postgendered television personality.
"They grow fast, as fast as embryonic stem cells, and they show great pluripotentiality
[meaning they can become many kinds of tissues]," said Atala.
In spite of the optimism generated by the recent research reports on the pluripotentiality
of human somatic stem cells, many scientists support the continuation of human embryonic stem cell research.
(4) One could theoretically harvest the cells of the morula prior to blastocyst formation; each of these thirty-two cells is capable of producing both placental and embryonic tissue and therefore has totipotentiality while the inner cell mass of a later embryo has pluripotentiality
. By the end of the first week of embryonic development, a blastocyst (a ball of cells with a cavity containing an oval disc of cells--the embryonic disc) is present containing an inner mass of 128 cells.
There is also functional pluripotentiality
, that is, no node within the system is responsible for only a single function, and any node can assume a (limited) variety of roles as situation and task demand.
(14,15) The sphere-derived cells were then transplanted into the amniotic cavity of the embryonic chicks prior to gastrulation to determine their pluripotentiality
. The transplanted sphere-derived cells did indeed give rise to cells from all three germ layers.
