They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each ...

They then showed that at low antigen concentrations (10–100 μg/ml), LSECs induced tolerance of naive OVA-specific CD8 + T cells but at high antigen concentrations (1 mg/ml) the T cells were ...

Mature ova are released from the ovary into the oviduct where they may be fertilised by sperm to form a zygote. In humans, fertilisation happens inside the woman’s body. This is a process called ...

Gametes are reproductive cells. Male gametes are called sperm. Female gametes are called ova. Fertilisation takes place in the oviduct when the nucleus of a sperm fuses with the nucleus of an ovum.

The researchers, including Katsuhiko Hayashi, a reproductive biology professor at Osaka University, created cells that can turn into ova and sperm from induced pluripotent stem (iPS) cells taken ...

Adding OVA to antigen-free diets restored T-cell quantities in PPs, suggesting that this effect is not specific to a ...
