Accumulating evidence indicates that epigenetic modifiers have key roles in genome-wide reprogramming and activation and repression of specific genes during mammalian germ-cell development.

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent ... inhibitor or growth factor to develop into embryoid bodies (EBs) ...

In utero, the blastocyst implants and all three embryonic germ layers are formed during gastrulation. Somatic stem cells are present in many fetal and post-natal tissues. Somatic stem cells are ...

such as the differing types of blood system cells. A second source is embryonic germ cells that are derived from the primordial reproductive tissues of aborted early fetuses. These are the cells ...

Because these blastoids only use ESCs derived from the epiblast, which becomes the embryo proper with germ layers, they model embryonic development’s pre-implantation period, up to seven days post ...

Pregnant women should avoid menthol-flavored vapes, warns new research. The chemicals in mentholated e-cigarettes may poses ...

Researchers have validated a specific cluster of microRNAs (miRNAs) as reliable biomarkers for detecting malignant testicular ...

Vaping during pregnancy is becoming more common, but its impact on early human development is not well understood. A new study by scientists at the University of California, Riverside, now reports ...

Adaptation of Human embryonic Stem Cells to in vitro culture In human ES cells, after prolonged culture, repetitive karyotypic changes have been noted (1, 2). These repetitive karyotypic changes are ...

These can be maintained in an undifferentiated state and can differentiate into the three germ layers endoderm, ectoderm, and mesoderm. Embryonic stem cells are pluripotent cells, so we believe ...

A new study reveals that menthol-flavored e-cigarettes may pose significant risks to fetal development, including the ...
