Researchers Use Stem Cells to Regenerate Muscle Nearly as Strong

Scientists Progress in Quest to Grow Muscle Tissue in Labs - "The researchers are now working on optimizing the growth of human muscle tissue, including finding a way to get blood flow to the tissue, the best source of cells and the best growing medium for the cells."

These cells from one fetus have saved the lives of millions of people.

One of the first and eventually most widely available fetal stem cell strains, WI-38 was harvested (in 1962) and has arguably helped save more lives in the ensuing years than any other created by researchers. Vaccines made using WI-38 cells have immunized hundreds of millions of people against rubella, rabies, adenovirus, polio, measles, chickenpox and shingles. WI-38 has helped epidemiologists identify viral culprits in disease outbreaks and understand cellular senescence. They have served as a normal control for disease comparison, and remain a leading tool for probing the secrets of cellular aging and cancer. Nature explores the line's controversial history.

It's Alive! Alive!

Watch stem cells spontaneously form into an eye in the lab. Japanese scientists at the Riken Centre for Developmental Biology have successfully encouraged mouse stem cells to form a crude eye - the first time the optic structure has been created outside a living host - with hopes of human cell trials in two years.

An Artificial Ovary

Using a 3-D petri dish, Researchers at Brown University and Women & Infants Hospital of Rhode Island have built a completely functional artificial human ovary that will allow doctors to harvest immature human egg cells (oocytes) and grow them into mature, ready-to-be-fertilized human eggs outside the body. (In vitro) The advance could eventually help preserve fertility for women facing chemotherapy or other medical treatments that may be destructive to ovarian folliculogenesis. Press Release.

21st. Century Snake Oil

"Con men used to travel town to town hawking medical remedies said to be made of Chinese snakes. Snake oil was useless and dangerous. So the FDA was created to put a stop to it and other food and drug scams. But, today, quack medicine has never been bigger. In the 21st century, snake oil has been replaced by bogus therapies using stem cells.

28 Days Later...more stem cells!

Scientists have discovered that "endometrial regenerative cells" (ERC's) -- in other words, human menstrual blood -- contains stem cells. ERC-derived stem cells seem to have a number of superior traits to both bone marrow derived and umbilical cord derived stem cells, the previous gold standards: they can give rise to a variety of different cell lines without differentiation, they multiply more quickly than other stem cells, they are able to replicate more times without adversely mutating, and they apparently do not need to be closely genetically matched to the recipient. Now some women have even begun banking their menstrual blood to preserve their stem cells through a company called "C'Elle: Your Monthly Miracle" -- check out their FAQ and online video. This follows last May's announcement that menstrual blood derived cells can pretty much cure Duchenne Muscular Dystrophy in mice, a disease for which there is no current therapeutic treatment available.

Fishy miscegenation

More cuckoo than cuckoos: mate two salmon, get a... trout! Just give the parents a sperm transplant. And the sperm stem cells work in females too:
...Injecting the male cells into female salmon sometimes worked, too, prompting five female salmon to ovulate trout eggs.... The stem cells were still primitive enough to switch gears from sperm-producers to egg-producers when they wound up inside female organs....

Is "Virgin Birth" hyperbolic enough?

I'm sure everyone remembers last year's kerfuffle about Hwang Woo-Suk, the disgraced scientist who fraudulently claimed to have created human embryonic stem cells by cloning. Well, it turns out he actually did something more remarkable - he created human stem cells from unfertilised eggs by parthenogenesis. The verification of this was published with a suitably dry title for consumption by scientists, but the popular press was quick to jump on more loaded phrases.

Of Stem Cells and Neanderthals

Come out, experts from the woodworks! Neu5Ac and Neu5Gc are sugars found on cells present in nearly every mammal, from chimps to pigs. When scientists altered the genes of mice so that they couldn't produce them, the mice died. However, unlike our closest relatives, humans lack a gene that makes Neu5Gc. The gene is not gone, but rendered silent by a fatal mutation, one that occured approximately 500,000 ago. Now, note that it is illegal to produce any new embryonic stem cell lines. Any scientist will tell you that extant and legal human stem cell lines have been existing in calf serum and often on layers of mouse "feeder" cells for growth. As such, they are immersed in a bath of antigen and if re-introdcued would elicit a strong immune response. I.e. although of human origin, they would be treated as foreign cells if injected. It is likely they would be rejected if injected with today's techniques anyway, but this may represent another significant hurdle for research, one that could be sidestepped with more progressive policy.

Stem cells target cancer tumors

Stem cells target cancer tumors. There has been some promising research with embryonic and adult stem cells in the fight against cancer. Meanwhile, California approved $3 billion for stem cell research, good news (debatably) since the 22 stem cell lines available for federally-funded research are contaminated with mouse cells and unusable for treatment in humans, but I wonder if California might end up in a federalism showdown with the new Senate over this. Maybe it will be less of an issue now that researchers have figured out how to derive stem cells from a morula, a four-day old embryo, without destroying it.

Stem Cell Research

The False Controversy of Stem Cell Research. Kinsley: In fact, thinking it through is a moral obligation, especially if you are on the side of the argument that wants to stop or slow this research. It's not complicated. An embryo used in stem-cell research (and fertility treatments) is three to five days past conception. It consists of a few dozen cells that together are too small to be seen without a microscope. It has no consciousness, no self-awareness, no ability to feel love or pain. The smallest insect is far more human in every respect except potential.
