'Bionic' Nerve To Bring Damaged Limbs And Organs Back To LifeScienceDaily (Oct. 18, 2009) — University of Manchester researchers have transformed fat tissue stem cells into nerve cells - and now plan to develop an artificial nerve that will bring damaged limbs and organs back to life. ‘The InkJet Approach to building life’Boston Globe (October 15, 2009) If you print over and over on a single piece of paper, the ink layers will eventually build up a three-dimensional structure. What if, scientists are asking, you use that same inkjet technology to print layers of cells on a tissue matrix? Can you eventually build up a living structure like a heart or a kidney? New Stem Cells by Reprogramming18-Oct-2009 Researchers are discovering new ways to help 'de-program' specialised cells so that they can be re-programmed to form a range of different types of tissue, an international meeting of stem cell biologists was told. California Takes Lead in Stem Cell Research, Scientist RecruitmentOctober 8, 2009 - Since California passed a $3 billion bond measure for stem cell research, recruitment of top scientists has outpaced every other state. The new funding has sparked the building of state-of-the-art facilities and a push for stem cell innovations. Transplanting Angina Patients' Stem Cells Shows Safety, Symptom Relief
The first
It is feasible to use a patient's own cord blood stem cells to
neutralize the body's autoimmune attack on the pancreas and help
restore the organ's ability to make insulin, researchers have
discovered. The finding from a small pilot study is a step toward
better treatments for diabetes.

Researchers have shown that bone marrow stem cells injected into a
damaged inner ear can speed hearing recovery after partial hearing
loss. Stem cell migration into the damaged area of the inner ear
improved hearing of high frequency sound (40 kHz) by 23% compared to
natural recovery in untreated animals.

In the first trial of its kind in the world, 60 patients who have
recently suffered a major heart attack will be injected with selected
stem cells from their own bone marrow during routine coronary bypass
surgery.

A current hope is that cardiac stem cells could one day be manipulated
to rebuild cardiac tissue damaged by heart disease. Scientists are now
addressing a fundamental question in the cardiac stem cell field, "What
are the molecular pathways required for expansion and development of
cardiac stem cells?"

In a survey of more than 1,000 infertility patients with frozen
embryos, 60 percent of patients report that they are likely to donate
their embryos to stem cell research, a level of donation that could
result in roughly 2,000 to 3,000 new embryonic stem cell lines.

Researchers have found a practical way to increase stem cells in blood,
suggesting a possible treatment to help patients recover from
chemotherapy or bone marrow transplant for cancer, regaining immune
function more quickly. The discovery marks the first time stem-cell
production has been induced by a small-molecule drug.
Wednesday, June 20, 2009, 9:00:00 PM Scientists have identified 1,155 genes under the control of a gene called Oct4 considered to be the master regulator of the stem cell state. For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types. But as genetic techniques have become increasingly powerful, many scientists have sought a more molecular definition of stem cells, based on the genes they express. |
Pre-cancerous Blood Diseases Can Be Products Of Their Environment When
blood-forming stem cells misbehave, causing pre-cancerous conditions
that can sometimes even progress to leukemia, the problem might not
always lie with them. Rather, two recent articles reveal that a bad
environment might be to blame.

Disorders of blood cells may begin in the biological environment where
the cells develop, not just with the cells themselves, according to a
new study.

Researchers have identified a protein that is part of the body's
natural defenses in oxygen-deprived conditions, a finding that could
rapidly lead to treatments for babies born before their eyes are
finished growing.

Artificial blood vessels have been engineered from muscle-derived stem
cells and a biodegradable polymer that exhibit extensive remodeling and
remain free of blockages when grafted into rats. This development has
potentially significant implications for the treatment of heart and
kidney diseases, where there is a critical need for new sources of
blood vessels for vascular grafts.

Current cancer therapies often are thwarted because they cannot
eliminate a small reservoir of multiple-drug-resistant tumor cells.
Researchers suggest that for chemotherapy to be truly effective in
treating lung cancers, for example, it must be able to target a small
subset of cancer stem cells, which they have shown share the same
protective mechanisms as normal lung stem cells.

Researchers have successfully isolated and cultured human hematopoietic
stem cells from fat, or adipose, tissue. Since it has been shown in
some cases that tumor cells contaminating bone marrow grafts are the
source of recurrent malignancies after autologous transplantation, this
may be another important source of cells for reconstituting the bone
marrow of patients undergoing intensive radiation therapy for blood
cancers.

Primates with severe Parkinson's disease were able to walk, move, and
eat better, and had diminished tremors after being injected with human
neural stem cells.

At the heart of most, if not all cancers, lie a handful of wayward stem
cells that feed the ever growing tumor mass, but their scarcity make it
difficult for scientists to study them. Now, times of plenty may lie
ahead as a breast cancer cell line -- established long ago -- turned
out to behave a lot like cancer stem cells.

Researchers examine moral questions and the scientific feasibility of
deriving Human embryonic stem cells lines in ways that avoid destroying
living human embryos.
Thursday, June 07, 2009, 9:00:00 PM
Researchers have found that deleting a gene important in embryo
development leads to premature aging and loss of stem cell reservoirs
in adult mice. This gene, ATR, is essential for the body's response to
damaged DNA, and mutations in proteins in the DNA damage response
underlie certain types of cancer and other disorders in humans.

As stem cells in the blood grow older, genetic mutations accumulate
that could be at the root of blood diseases that strike people as they
age, according to work done in mice by researchers at the Stanford
University School of Medicine.

Researchers at the Institute for Stem Cell Biology and Medicine at UCLA
were able to take normal tissue cells and reprogram them into cells
with the same unlimited properties as embryonic stem cells, the cells
that are able to give rise to every cell type found in the body.

A groundbreaking surgical therapy capable of stabilising and restoring
vision in the vast majority of patients who currently suffer blindness
through Age-Related Macular Degeneration is to be taken to clinical
trial by scientists.
