Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Depending on the biological life cycle of the organism , gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis.
Now researchers at private biotech companies like Conception Bio and Gameto are racing to see if they can develop this in vitro gametogenesis (IVG) technology as a way to safely enable post ...
In vitro studies permit a species-specific, simpler, more convenient, and more detailed analysis than can be done with the whole organism. Just as studies in whole animals more and more replace human trials, so are in vitro studies replacing studies in whole animals.
In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process , then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
The first pregnancy achieved through in vitro human fertilisation of a human oocyte was reported in The Lancet from the Monash University team of Carl Wood, John Leeton and Alan Trounson [8] in 1973, although it lasted only a few days and would today be called a biochemical pregnancy.
Advances in fertility technology like egg freezing and in-vitro fertilization have made pregnancy in your 40s and 50s even more possible. Just ask these women. This Mother Had A Baby At 50 Without ...
Under special conditions in vitro germ cells can acquire properties similar to those of embryonic stem cells (ESCs). The underlying mechanism of that change is still unknown. These changed cells are then called embryonic germ cells. Both cell types are pluripotent in vitro, but only ESCs have proven pluripotency in vivo. Recent studies have ...
In vitro spermatogenesis is the process of creating male gametes (spermatozoa) outside of the body in a culture system. The process could be useful for fertility preservation, infertility treatment and may further develop the understanding of spermatogenesis at the cellular and molecular level.
