Embryonic stem (ES) cells are cells derived from the early embryo that can be propagated
indefinitely in the primitive undifferentiated state while remaining pluripotent; they share …

The term ''oxidative stress” refers to a cell's state characterized by excessive production of
reactive oxygen species (ROS) and oxidative stress is one of the most important regulatory …

The remarkable developmental potential and replicative capacity of human embryonic stem
(ES) cells promise an almost unlimited supply of specific cell types for transplantation …

We have identified an easily attainable source of primitive, potentially multipotent stem cells
from Wharton's jelly, the matrix of umbilical cord. Wharton's jelly cells have been propagated …

Human embryonic stem (hES) cells, derived from blastocysts, are capable of unlimited self-
renewal and differentiation into all cell lineages of the body. Because of their pluripotent …

Embryonic stem (ES) cells rely on growth factors provided by feeder cells or exogenously to
maintain their pluripotency. In order to identify such factors, we have established sub-lines of …

Circulating CD14+ monocytes are precursors of phagocytes, such as macrophages and
dendritic cells. Here we report primitive cells with a fibroblast-like morphology derived from …

This update discusses what is known regarding embryonic and adult tissue-derived
pluripotent stem cells, including the mechanisms underlying self-renewal without …

Growth of human embryonic stem (hES) cells as a pluripotent population requires a balance
between survival, proliferation and self-renewal signals. Here we demonstrate that hES cells …

The past few years have seen remarkable progress in our understanding of embryonic stem
cell (ES cell) biology. The necessity of examining human ES cells in culture, coupled with …
