What Are Stem Cells? Uses, Types, and Where They Come From
Jess

Advantages and Challenges of Stem Cell Therapy
This page discusses the benefits of stem cell therapy as well as the clinical, ethical, and social issues surrounding their use.
Advantages of Stem Cells: Stem cells have the unique ability to divide and produce new cells, which can then differentiate into various cell types. This characteristic gives them the potential to be transplanted into patients to treat medical conditions and diseases by replacing damaged or destroyed cells.
Highlight: The regenerative potential of stem cells makes them a powerful tool in treating conditions where tissue repair is crucial.
Clinical, Ethical, and Social Issues: The challenges associated with stem cell research and therapy vary depending on the type of stem cells used and whether they are used for therapy or research.
Clinical Issues:
- There is no guarantee of success for these therapies.
- Finding suitable stem cell donors can be difficult.
- Mutations have been observed in stem cells cultured for multiple generations, with some mutated stem cells behaving like cancer cells.
Vocabulary: Therapeutic cloning is a process where stem cells are created from an embryo that is a genetic copy of the patient's cells.
Ethical Issues:
- The use of unused embryos from in vitro fertilization for embryonic stem cells raises ethical concerns.
- Questions arise about the morality of creating and destroying embryos for therapeutic cloning.
- Debates continue about at what stage of development an embryo should be regarded and treated as a person.
Social Issues:
- There is ongoing discussion about whether the benefits of stem cell use outweigh the risks.
- Concerns exist about the potential exploitation of patients who may pay for expensive treatments and be given false hope of a cure, especially since stem cell therapies are still in developmental stages.
Quote: "At what stage of its development should an embryo be regarded as, and treated as a person?"
This question encapsulates one of the central ethical dilemmas in stem cell research and therapy.
Stem Cell Sources and Potential Applications
This page provides an overview of stem cell sources and their potential medical applications. Where do stem cells come from? Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also exploring genetic reprogramming techniques to develop stem cells from other cells.
Types of stem cells found in adult tissues include those from:
- The brain
- Bone marrow
- Blood and blood vessels
- Skeletal muscles
- Skin
- The liver
Embryonic stem cells are derived from blastocysts, which form 3-5 days after fertilization. These cells have the potential to develop into any cell type in the body.
Definition: A blastocyst is a ball of cells that forms in the early stages of embryonic development, containing stem cells that will later implant in the womb.
The most common current use of stem cells is in hematopoietic stem cell transplants, such as bone marrow transplantation. These treatments are used for blood and immune system disorders or to rebuild the blood system after cancer treatments.
Example: Bone marrow transplantation is a well-established stem cell therapy used to treat certain types of cancer and blood disorders.
What can stem cells be used for? The potential conditions that stem cells could treat include:
- Spinal cord injuries
- Type 1 diabetes
- Parkinson's disease
- Amyotrophic lateral sclerosis
- Alzheimer's disease
- Heart disease
- Stroke
- Burns
- Cancer
- Osteoarthritis
Highlight: The versatility of stem cells makes them a promising avenue for treating a wide range of medical conditions, particularly those involving tissue damage or degeneration.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
