The electron microscope study has shown that the snail myocardium contains a population of undifferentiated cells
(UCs) and a number of poorly and moderately differentiated myocytes.
In all these stages, labeled nuclei were always observed in undifferentiated cells
and peritoneocytes (Figs.
The total number of cells and undifferentiated cells
in the lymphoid nodules in helminthic infestation increases, and the content of macrophages and plasma cells is reduced.
6) Cancers are formed by the uncontrolled proliferation of relatively undifferentiated cells
RESULTS: In undifferentiated cells
, AgNP-C impaired DNA synthesis, but to a lesser extent than an equivalent nominal concentration of [Ag.
Following an overview of stem cells as undifferentiated cells
that can morph into any cell or tissue in adults, Taupin (biotechnology, Dublin City University, Dublin, Ireland) discusses the role of enhanced neurogenesis in Alzheimer's disease--perhaps an attempt at repair, the potential of new therapies for central nervous system (CNS) disorders and injuries, the controversial use of newborn stem cells in the adult CNS, stem cell research as a model for understanding neurological disorders, and combining cellular and gene therapies to treat brain cancer.
The journal said the group succeeded in creating 99 percent pure human and mouse cardiomyocytes by marking the cells with fluorescent dye that labels mitochondria particularly abundant in cardiomyocytes and eliminating undifferentiated cells
that are risks in becoming tumors.
Stage V (until the fourth day after laying)--Undifferentiated cells
accumulate under the embryonic epidermis, which becomes thicker and multilayered due to proliferation of the undifferentiated cells
, thereby giving origin to the definitive epidermis.
CARBON DIOXIDE CHANGES UNDIFFERENTIATED CELLS--When carbon dioxide is bubbled into a solution containing undifferentiated cells
that have just begun to grow after egg fertilization, the cells become brain cells.
These undifferentiated cells
are most numerous in nodes--the places where branches and buds emerge from stems--and in buds that form on shallow roots and low-growing stems.
A blastocyst is a set of from eight to about 200, undifferentiated cells
