I found this website with interesting facts and scientific research on stem cells. I learned that all the cells in your body come from stem cells and scientists are currently trying to use them for medical regenerative treatment. The article talks about how stem cells can be turned into specialized cells and can replace and repair old or damaged organs in order to keep the body functioning. This relates back to our lesson where we learn how specialized cells are created and used.
In this article, it talks about how neural stem cells (stem cells that give rise to other cells in the nervous system) have created a line of spinal cord, showing a diverse promise. Researchers have appeared to have made spinal cord neural stem cells by taking pluripotent stem cells from a human. This means that the pluripotent stem cells helped to differentiate into a population of cells distributed in the spinal cord, helping the spinal cord function with neural stem cells that can make nerve cells, etc.
"Scientists Create Personalized Stem Cells, Raising Hopes for Diabetes Cure" // National Geographic
In this article, the author talks about the process of which researchers used a technique known as somatic cell nuclear transfer, where ideally, they would use stem cells to create beta cells that the body would recognize as its own. The patient is a 32 year old female who developed Type 1 diabetes, and is incapable of producing insulin. The researchers inserted the nucleus from one of the patient's skin cell into a donor egg cell, and grew it until it became a blastocyst, and influenced the embryonic stem cells to become beta cells. As predicted, the beta cells produced insulin as they would in the body. However, in Type-1 diabetes, the immune system treats the body's beta cells as invaders, destroying them, so even if new ones were introduced, they would still be attacked. The reason is still unknown, but researchers are working towards finding a way around it in order to devise a cure for diabetes.
In this article, the writer talks about stem cells that were taken from baby teeth to help repair injured permanent teeth. Patients were told to give pulp of one of their healthy tooth to be brought to a lab for it to have grown before implanting in injured tooth. Researchers say that this treatment gives patients sensation back in their teeth.
While browsing the internet I stumbled upon this post which I found absolutely hilarious... which makes me wonder if Ms. Loree's sense of humor is rubbing off of me :)
Anyways, this post is about three stem cells who were all talking about who they wanted to be on 'Career Day'. The first stem cell was fully drawn to be a neuron and the next one looked slightly hesitant to being a muscle cell...all while the third one looked utterly determined to be Optimus Prime... you know the Transformers...
Frankly, I don't quite think that the third cell completely comprehended what it meant to have a 'cell type', like a bone or red blood cell... but at the same time I don't really want to crush his dreams, so I'll just leave it be.
Anyways I hope you found that comic just as fas-cell-lating as I did. (please ignore that pun I spent way too much time making)
This article is about cancer stem cells and how scientists have found a way to use nanotechnology to destroy them. Stem cells divide into more cells, however sometimes those are tumor cells that harm the body. Using drug-filled nanoparticles, they can be killed.
Today I read an article about how stem cells are being used to treat various diseases. One of the diseases it talked about was alpha thalessemia, which can lead to dangerously low levels of red blood cells. This means there will be less O2 throughout the body. Neither parent is affected but if their genes combine in a certain way then their children could be. Two parents discovered through an ultrasound of their 18 week old daughter that she had the condition. Her chance of survival was grim and if she did she would have depended on blood transfusions for the rest of her life. So the doctor suggested an experimental treatment by using a stemcell transplant given to the baby in the utero. To get the stemcells they needed to extract it from the bone marrow of the mom which is dangerous considering she's pregnant, but she did it anyways. Her daughter would be the fetus in the world to receive stem cells from her mother in a carefully monitored clinical trial.
In this article, they talk about how using stem cells can make permanent disabilities reversible. For example, a scientist was using induced pluripotent stem cells to create new retina cells to replace the dead ones that were there before.
This program offers non medical procedures using NSI stem cells which can treat bad pain and joint injuries. Some examples are, arthritis, back pain, shoulder pain, and muscle injuries.
"In 2006, Kazutoshi Takahashi and Shinya Yamanaka reprogrammed mice fibroblast cells, which can produce only other fibroblast cells, to become pluripotent stem cells, which have the capacity to produce many different types of cells. Takahashi and Yamanaka also experimented with human cell cultures in 2007. Each worked at Kyoto University in Kyoto, Japan. They called the pluripotent stem cells that they produced induced pluripotent stem cells (iPSCs) because they had induced the adult cells, called differentiated cells, to become pluripotent stem cells through genetic manipulation. Yamanaka received the Nobel Prize in Physiology or Medicine in 2012, along with John Gurdon, as their work showed scientists how to reprogram mature cells to become pluripotent."
This an excerpt that I took from an article. This information shows that the research in IPSC's is fairly recent. It stood out to me because IPSC's have developed into something amazing in a short amount of time. I hope it can integrate into a useful part of medicine soon
This article talks about the future of stem cells. Japanese scientists, have found a way to grow tissues that make a human eyeball, with a sample of adult skin. Assorted types of human stem cells, can gain possession of the attributes of the cornea, lens, and retina.
Write something about yourself. No need to be fancy, just an overview.
