The evolution of biomedical science can be appreciated through studies of hemoglobin, the oxygen-carrying protein in red cells. Before molecular cloning, the geneticist Arno Motulsky noted, “Many ...

Both late-gestation and adult human forebrain contain large numbers of oligodendrocyte progenitor cells (OPCs). These cells may be identified by their A2B5 + PSA-NCAM-phenotype (positive for the early ...

The blueprint of the adult brain may be mapped out far earlier than we thought. In fact, some 60 percent of the circuits that make up the adult brain may take shape before we are even born, according ...

Researchers have developed a proof-of-concept treatment for blood disorders like sickle cell disease and beta-thalassemia that could raise hemoglobin levels by activating production of both fetal and ...

The fundamental organization of brain networks is established in utero during the second and third trimesters of fetal development, according to research published in JNeurosci. The finding lays the ...

While it is generally believed that fetuses are at high risk of developing cancers, including leukemia, after low doses of radiation, it has been reported that atomic bomb survivors exposed in utero ...

Researchers have discovered there is a division of labor among immune cells that fight invading pathogens in the body. Cornell University researchers have discovered there is a division of labor among ...

An embryo starts out as just a single cell. It’s not long before it divides into two cells, then four, then eight, and so on — a process marked by rapid growth, in which these early, unspecialized ...
