Stem Cell Awareness Day: October 8, 2014
Tomorrow, Wednesday, October 8, is Stem Cell Awareness Day. It’s a day to celebrate stem cells, have discussions on what stem cell research is, and learn about potential benefits and disease treatments using stem cells. Many national and international events (especially in California) are taking place to celebrate this special day — the California Institute … Continue reading
First Transplant using Induced Pluripotent Stem Cells: Treating Blindness
Induced pluripotent stem cells (iPSCs) have enormous potential for being used in tissue transplants and therapies. Why is this? It’s because iPSCs can be made using virtually any cells from a person’s body — such as skin or fat samples that wouldn’t be missed. (And since they’re the patient’s own cells, the immune system should … Continue reading
STAP Retraction Imminent
In January, two papers were published in the prestigious journal Nature showing how to make stem cells using a shockingly simple and completely novel approach — by putting cells in an acid bath. The resultant mouse stem cells were called STAP cells (for stimulus-triggered acquisition of pluripotency). However, since then, other researchers have had great … Continue reading
Stem Cell Trials to Treat Spinal Cord Injuries
While human embryonic stem cells (hESCs) were originally created in 1998, it wasn’t until 2009 — over a decade later — that they were approved by the FDA for use in a clinical trial in people. It was a long wait, but the trial was quite the promising one. The clinical trial, undertaken by the … Continue reading
Biology-Related Exhibits at the Miraikan Museum in Tokyo
Note: The Biology Bytes blog will only be updated on Tuesday this week (the author is traveling in Japan). Regular Tuesday/Thursday updates will resume on June 3. Whenever I travel internationally, I make a point of visiting science museums. It’s fascinating not only to learn scientific concepts from them, but also to see what specific … Continue reading
The Latest on the STAP Controversy
Back in late January, two papers were published in the prestigious journal Nature showing a completely novel and shockingly simply way to make stem cells – the approach used an acid bath. Since then, there’s been huge controversy surrounding the creation of these mouse stem cells, called STAP cells (for stimulus-triggered aquisition of pluripotency). This … Continue reading
How a Substrate Affects a Stem Cell’s Fate
Much of the stem cell field is devoted to figuring out how to direct what stem cells turn into. (In stem cell terminology, the process of having a stem cell become a different type of cell is called differentiation.) By better controlling a stem cell’s fate, we can more efficiently turn the cell into a … Continue reading
Reaching K-12: Biology-Related Science Fair Project Ideas
Doing a science fair project can be very daunting, especially for a child who’s never done one before. To help out the burgeoning biologist (or parent of a biologist-to-be), here we’ll explore some great biology-based science fair project ideas provided by Science Buddies. And since deadlines for many fairs are quickly approaching, we’ll focus on … Continue reading
How to Make Stem Cells… Using Acid!
Just yesterday, two papers were published in the journal Nature showing a completely novel way to make stem cells – the approach uses an acid bath. This method is rather shocking in its simplicity, and it’s unclear why or how it works, but somehow it does. Basically, the researchers took adult (somatic) cells from young … Continue reading
Biology Bytes: The Books
The Biology Bytes blog was inspired by the publication of two separate books by the same author. If you enjoy reading about the fascinating critters and plants that are all around us, or the latest developments in stem cell research or modern medicine in general, or have simply been enjoying reading the wide variety of … Continue reading
