Those who volunteer to donate their own or their ill children's somatic cells
for iPS cell research may do so in the hopes of directly or indirectly benefiting themselves or their loved ones through downstream therapeutic applications of these genetically-matched stem cell lines.
Microbiological, chemical and somatic cell
analyses were performed to evaluate the effect of microfiltration on the composition of skim milk.
Instead, the somatic cell
count (SCC) is considered to be the most suitable indicator trait for mastitis resistance in view of its medium to high genetic correlation with mastitis (0.
The Human Cloning Prohibition Act of 2011 would make somatic cell
nuclear transfer (SCNT) illegal and would impose a felony charge on scientists who conduct such research.
Our findings provide evidence for an emerging view that somatic cells
may be reprogrammed safely and simply by defined chemicals and other factors, which may facilitate their clinical use," said Professor Ahmad.
Centrioles have been traced in all stages of pre-implantation embryogenesis and also in embryonic stem cells and the sperm centriole is undoubtedly the precursor of centrioles in all foetal and adult somatic cells
To improve the efficiency numerous strategies have applied using somatic cells
from donors of various ages, passage and culture conditions (Silvestre et al.
By 1986, West had read the work of biologist Howard Cook who found that telomeres shortened with each generation in white blood cells (which are somatic cells
and have finite life spans), but maintained their length in germ-line cells like sperm.
elegans roundworm, induce "mortal" somatic cells
to express some of the genes that allow the "immortality" of reproductive germline cells.
Composition of somatic cells

(%) Type of mammary secretion PMN Macrophage Lymphocytes Epithelial cells Milk 3 80 16 2 Colostrum 62 35 4 0 Dry gland secretion 3 89 7 1 PMN = Polymorphonuclear cells.
For example, the NIH Stem Cell Task Force will develop several funding opportunity announcements asking for grant applications proposing research on human pluripotent stem cells derived from non-embryonic sources, such as somatic cells
or cells found in amniotic fluid.
The fourth proposal is to reprogram differentiated somatic cells
so as to restore to them the pluripotency of ES cells.
