The mammoth cells were implanted into mouse oocytes, which are ovarian cells involved in embryonic development.
|
|
Because tumour cells are bound more loosely than healthy cells, liposomes squeeze between them more easily.
|
|
Still, our cells are different — a neuron looks nothing like the cells that line your stomach.
|
|
They generate the cells of the nervous system, like neurons and glial cells, throughout our lives.
|
|
Stem cells are special cells kept in reserve as means to repair and regrow damaged tissue.
|
|
Microscopic images show the macrophage immune cells (the colorful splotches) proliferating and working in cancerous cells.
|
|
The spores then burst out of the cells and can infect other cells, or other frogs.
|
|
Henrietta Lacks died the same year those cells were harvested, but her cells have lived on.
|
|
The engineered skin cells and stem cells were then used to grow skin in the lab.
|
|
Unfortunately, the stem cells tend to become exhausted when they've produced around 50,000 red blood cells.
|
|
To make cells responsive to light, the team basically added eye features to non-eye cells.
|
|
Cord blood stem cells, in particular, can grow to replace diseased bone marrow with healthy cells.
|
|
We could reprogram the cone cells to sense UV light and then transplant the cells themselves.
|
|
"Bus stops are powered with solar cells, you could power this with solar cells," he said.
|
|
It is important to note that descendent cells are not the cells of the aborted child.
|
|
The second has cells growing directly on electrodes, which measure electrically what cells are up to.
|
|
White blood cells are removed from the body and altered to target cancer cells when returned.
|
|
Studies suggest they hijack white blood cells, transforming them into soothing cells that prevent inflammatory disease.
|
|
Multiple myeloma is a cancer of plasma cells, the white blood cells responsible for producing antibodies.
|
|
That blunted the healing process: Fewer stem cells were activated, so fewer new muscle cells appeared.
|
|
These cells were stimulated to grow into brain cells and were then cultivated for eight weeks.
|
|
They gently coaxed the top layers of cells, known as epithelial cells, from the underlying tissue.
|
|
As if by magic, he reported, the stem cells turned into heart cells and repaired damage.
|
|
But when white blood cells swarm in to attack the cancer cells, they bounce back, rebuffed.
|
|
"We find cells in places where we thought there wouldn't be any cells," said Dr. Daniel.
|
|
The transplanted immune cells, now resistant to H.I.V., seem to have fully replaced his vulnerable cells.
|
|
His cellblock seemed to him like an enormous warehouse, with inmates in cells stacked upon cells.
|
|
SMALL CELLS MEAN YOU NEED LOTS OF WIRED LINE CONNECTIVITY TO MAKE THE SMALL CELLS WORK.
|
|
The trouble is, T-cells don't recognize cancerous cells as an adversary, leaving the body vulnerable.
|
|
The tumor grows by turning normal brain cells into stem cells, which continuously replicate and regrow.
|
|
They took skin cells from a 70-year-old patient and derived iPS cells from them.
|
|
Not just any cells, though—scientists use my white blood cells to make what are called induced pluripotent stem cells, meaning that they can grow into any cell in the body.
|
|
The hypothesis from rodent studies is that the fetal cells might jump in and replace mom's tissue, acting as a source of stem cells to replace mom's old or diseased cells.
|
|
Two other types of cells, the extra-embryonic trophoblast stem cells and the endoderm stem cells, begin to form patterns that will eventually become a placenta and a yolk sac, respectively.
|
|
A team of scientists at Indiana University might be getting closer to that future, using pluripotent stem cells, cells from the body that can be turned back into blank slate cells.
|
|
These blood cells can help clear debris and dying cells from the injury site, signal the rebuilding process to replace lost cells, and ward off foreign invaders like bacteria or viruses.
|
|
The hypothesis, widely held at the time, was that the body had stem cells — immature primitive cells — that in the right environment could turn into any other cells in the body.
|
|
Dr. Yamanaka's method is now routinely used to change adult tissue cells into cells very similar to the embryonic stem cells produced in the first few divisions of a fertilized egg.
|
|
One unit of cord blood yields enough cells to treat five patients, she said, and in two weeks the natural killer cells can be expanded 500-fold, to a billion cells.
|
|
Nerve cells are kept alive by and connected to other cells called glia; outside of the central nervous system, one of the two major types of glia are called Schwann cells.
