Very small embryonic-like stem cells (VSELs) are a rare and intriguing subpopulation of adult stem cells that exhibit molecular signatures reminiscent of embryonic stem cells. Identified in various ...

January 27, 2009 — Geron Corp announced it has received US Food and Drug Administration (FDA) approval for a phase 1 trial of GRNOPC1, a cell therapy derived from human embryonic stem cells (hESC), in ...

Embryonic stem cells (ESCs) are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4 th to 7 th day after fertilization. In normal embryonic ...

Between 1998 and 2009, research being conducted using human embryonic stem (hES) cells expanded primarily using private funds because of restrictions on the use of federal funds for such research.

Researchers have succeeded in generating high-quality feline embryonic stem cells using sperm and eggs from testes and ovaries discarded during sterilization surgery. As different as they may seem, ...

Could wounded skin someday regrow perfectly without scars? A new study by Harvard stem cell biologists published in Cell reveals a way to fully regenerate skin by unblocking an embryonic healing ...

A team of researchers has reported a breakthrough in making sperm cell precursors in vitro that could be used in a number of ...

In mice wounded three days before birth, the skin regenerated diverse cell types and closely resembled unwounded skin.

When you were first conceived, you were a single cell. From this basic fact, we can extrapolate a few things, most especially that all the cells that make up your body today came (indirectly) from ...

A small shift in nutrient supply has led to the development of a new method to rejuvenate stem cells. Scientists at the University of Copenhagen found that these “super stem cells” remain healthier in ...

A cut in the womb can vanish almost without a trace. The same injury a few days after birth leaves behind a scar.
