Sperm Made From Human Bone Marrow
Welcome back!
Scientists have successfully made immature sperm cells using human bone marrow, which is in its very early stages. Researchers hope to grow them into fully developed sperm within 5 years to use in fertility treatments in a report from BBC News.
Proposed new laws would ban on using artificially created sperm or eggs in assisted reproduction in the UK.
The researchers from the Universities of Göttingen and Münster and the Medical School of Hannover isolated adult stem cells – cells that have the ability to become many types of tissue in the body – from bone marrow samples taken from male volunteers.
But the researchers induced a small number of them to develop into what appeared to be spermatagonial cells – cells found in the testes which would normally develop into mature sperm cells.
The changing of stem cell types observed by the researchers, from pre-muscle to pre-reproductive cells, is known as trans-differentiation.
How sperm is made from Bone Marrow Tissue
Now this just looks down and nasty. Shudder! At times like these I’m glad I’m not a man.
1) Stem cells isolated from bone marrow of male volunteers
2) In laboratory, stem cells cultured and identified. Some induced to become spermatological cells – which normally become sperm cells
3) Transplantation of cells into testicle – so far performed in mice
The findings were presented at an international fertility conference and are published in Gamete Biology: Emerging Frontiers on Fertility and Contraceptive Development.
