In a novel approach at preserving fertility, researchers have successfully produced live offspring from cryopreserved testicle tissue.
You may think that cryopreserving testicle tissue is kind of a stretch- but many cancer patients undergoing treatments don’t have options when it comes to preserving fertility. Doctors can cryopreserve sperm if the patient has already reached puberty, but for young boys, that’s not an option.
By cryopreserving testicle tissue, researchers are able to thaw tissue at a later date and induce the production of sperm. This research was carried out in mice, and through artificial insemination, eight healthy offspring were produced! Amazingly, thawed tissue was able to produce sperm just as well as unfrozen tissue.
There’s still some work to be done before this research can be translated into humans. But as more and more pediatric cancer patients are being successfully cured of their diseases, this research could mean life-changing, long-term fertility options. Read more about it here:
A trial at the University of Pennsylvania’s school of veterinary medicine is introducing a groundbreaking treatment for dogs suffering from osteosarcoma. Dogs in the trial are receiving an experimental vaccine that trains the immune system to recognize tumor cells and to kill them- and it’s working!
More than 10,000 dogs are diagnosed each year with osteosarcoma, which is an aggressive type of bone cancer. Most dogs die within a year of diagnosis, but in this trial, many of the dogs in the study have survived for more than two years. Check out this video to see an update on Denali, a therapy dog enrolled in the trial.
The biology of canine osteosarcoma is the same as the biology of these tumors in children, so the information gained from this study could one day help children with osteosarcoma. There are also types of breast cancer that have similarities to osteosarcoma, so the human benefits aren’t limited to one type of cancer.
Researchers are looking for more dogs with osteosarcoma to participate in this trial. Does your dog qualify? If so, check out the link here for more information.
It’s been known for decades that the incidence of acute lymphoblastic leukemia (ALL) is 20 times higher in children with Down syndrome than in the general population. And now- thanks to mice- researchers know why!
People with Down syndrome have an extra copy of part or all of chromosome 21. And by working with mice that carry extra copies of genes that are found on chromosome 21, researchers have identified the link between Down syndrome and ALL. Long story short, this particular type of leukemia is caused by an excess of abnormal white blood cells that are supposed to fight infections but don’t work properly. These mice led researchers to the specific proteins involved in this process, and they found- and confirmed in human cell samples- that the gene responsible for spurring the creation of these abnormal cells was an extra gene on chromosome 21. Link: discovered.
While there currently aren’t any drugs that target this specific gene, researchers now know where to focus. Now that they know where the problem lies, they can work to develop drugs that could potentially reduce the chances of a child with Down syndrome developing leukemia! It’s also possible that ALL patients without Down syndrome could benefit from this research.
It’s not good news yet; there’s still work to be done. But I support the fight against pediatric cancer- and the mice do, too!
