Damaged knee joints might one day be repaired with cartilage grown
from stem cells in a laboratory, based on research by Professor
Kyriacos Athanasiou, chair of the UC Davis Department of
Biomedical Engineering and his colleagues.
Using adult stem cells from bone marrow and skin as well as human
embryonic stem cells, Athanasiou and his group have already grown
cartilage tissue in the lab. Now they are experimenting with various
chemical and mechanical stimuli to improve its properties.
Cartilage is one of the very rare tissues that lacks the ability to heal
itself. When damaged by injury or osteoarthritis, the effects can be
"If I cut a tiny line on articular cartilage (the cartilage that covers the
surfaces of bones at joints), it will never be erased," Athanasiou said.
"It's like writing on the moon. If I go back to look at it a year later, it
Work that Athanasiou's group began in the early 1990s at Rice
University has resulted in the only FDA-approved products for
treatment of small lesions on articular cartilage. (In total, Athanaisou's
patents have resulted in 15 FDA-approved products.)
"This will be live, biological cartilage that will not only fill defects,
but will potentially be able to resurface the entire surface of joints that
have been destroyed by osteoarthritis," Athanasiou said. Currently,
joint replacements using metal and plastic prosthetics are the only
recourse for the one in five adults who will suffer major joint damage
Publication jsonline.com Stem cell pioneer predicts reprogramming will change drug development
Stem cell pioneer James Thomson of the University of Wisconsin-
Madison told members of the Milwaukee Academy of Medicine that

techniques that allow scientists to change human skin cells into
something almost identical to embryonic stem cells will change the
way new drugs are developed in the next 10 or 20 years.
During a half-hour talk Tuesday night, Thomson guided members of
the academy through the revolutionary developments in cell biology -
- from his isolation of embryonic stem cells in monkeys and then
humans to the cloning of Dolly the sheep by the Scottish scientist Ian
Wilmut and finally the reprogramming revolution ushered in by
Thomson, his UW collaborator Junying Yu and Japanese scientist
Thomson, who was awarded the academy's 2009 Distinguished
Achievement Award, cautioned that the stem cell field is in danger of
falling prey to the same kind of hype that greeted the gene therapy
field. Nonetheless, he predicted stem cells and reprogramming "will
change human medicine in ways we cannot fully predict."
Thomson did stress that stem cell advances are most likely to
revolutionize medicine in ways that don't make the front page of a
newspaper: for example, by allowing scientists to watch diseases
unfold at the cellular level; and by allowing pharmaceutical
companies to test thousands of drugs against sick or damaged cells in
Although far more attention is paid to the idea of one day treating
diseases through cell transplantation, Thomson said that is less likely
to take place anytime soon and will probably be too costly for many
Publication Prweb.com Spinal Cord Injury Patients Demonstrate Progress after Stem Cell Therapy at the XCell-Center
The XCell-Center has released results from a follow-up study of 115
spinal cord injury patients treated with autologous bone marrow stem
cells. Overall, nearly 6o% improved following treatment.
These results support the premise that spinal cord injury patients can
be treated safely and effectively with autologous stem cell therapy.
The most common improvement, reported by more than 6 out of
every 10 patients, was the return of feeling to the hands, feet, arms,
Muscle strength and endurance improved in over 50% of those treated
and more than 4 in 10 patients reported a decrease in muscle
spasticity. "We returned home and one week after the transplant I

cell therapy has for a majority of spinal injury patients who undergo

The treatment begins by collecting a small amount bone marrow from
the patient's hip bone using a thin needle under local anesthesia. The
stem cells are then separated from the bone marrow at the XCell-
Center's EU certified cGMP laboratory (current good manufacturing
process). Before the cells leave the lab, they are counted and their
vitality is confirmed. The last step of the treatment is the minimally
invasive implantation procedure, which consists of injecting the stem
cells into the patient's spinal fluid using a spinal needle under local

Publication sciencedaily.com New Method To Coax Retinal Cells From Stem Cells
Researchers have developed a new method for identifying retinal
precursor cells derived from human embryonic stem cells (those from
embryonic tissue) and induced pluripotent stem cells (those from
adult skin cells). These precursor cells represent the earliest stages of
retinal development. The new method results in a greater yield of
retinal cells from stem cells and could be used to better understand
disease processes and realize effective treatments for eye disorders.
The findings were presented at Neuroscience 2009, the annual
meeting of the Society for Neuroscience and the world's largest source
of emerging news about brain science and health.
Problems associated with retinal degenerative diseases are due to the
injury and death of neurons, or support cells that can't regenerate. The
cell types primarily affected are the light-sensing rod and cone
photoreceptors and the adjacent retinal pigment epithelium, which
maintains proper photoreceptor health and function. If these cells
could be replaced or bypassed, sight could be restored.
"So far, a number of human cell sources have been examined to see if
they produce multiple retinal cell types, but most candidates have
November 4, 2009
proven inadequate," said Jason S. Meyer, PhD, at University of
Wisconsin, the study's lead author. "In comparison, human stem cells
have produced cells that are clearly of a retinal nature."
When the stem cells were isolated and matured, specific retinal cell
types could be identified, including photoreceptors and retinal
pigment epithelium. Using this new system, the authors could regulate
the production of certain cell types by adding or removing particular
compounds to the cells. "This ability could aid in the discovery of
new therapeutic approaches to a variety of disorders affecting the
retina," Meyer said. "These findings could lead to treatments for other
neurological disorders, in addition to eye diseases."

When Should your Child Stay Home from School? General Guidelines for When not to Report to School Good attendance at school is important in order for a child to do well. However, there will be times when your child is really too ill to attend. Either they are contagious to the other students or they feel so poorly that they would gain nothing from being at school. The following symptoms can
