what types of tissues.

other types of tissue, including muscle, skin, breast, and brain, to model tumors in those regions, the researchers say.
The skin's ability to grow back after a wound led scientists to assume that it must contain stem cells, immature cells that can rapidly differentiate into many
different types of tissue.
This «mysterious» connection becomes easier to grasp when you understand that your brain and your gut are actually biologically identical, as they're created out of the
same type of tissue.
He believes they may be able to get around this obstacle with advances in generating stem cells from patient cells that have already developed into a
specific type of tissue, such as skin.
Taurine is a compound similar to an amino acid that's found in many
types of tissues in the body.
As time passes and the cells start dividing further and further, they start specializing into becoming a specific
type of tissue which has a specific function, thus forming all the different parts that comprise a human.
Understanding stem / progenitor cells — which can develop into
various types of tissue — are key to developing novel approaches for regenerative medicine.
Projects that would previously have taken hundreds of people and long time schedules can now be done by individual labs, meaning
more types of tissues in more conditions can be investigated.
Stem cells are undifferentiated cells that can become different
types of tissue as they mature; injected into a heart that's been ravaged by a coronary, they can form healthy new muscle to replace what has been lost.
Mistaking
certain types of tissues for harmful substances, your body turns these antibodies against itself, wreaking havoc on your organs.
These cells protect many
types of tissues from infection, but they can also promote chronic inflammatory conditions like Crohn's disease, which specifically targets the intestinal tract.
Says Sharma, «Our findings are very relevant not just for bladder regeneration but for other
types of tissue regeneration where foreign materials are utilized for structural support.
Using what's known as multimodal imaging technologies, which combine several methods such as PET - CT and simultaneous measurement, scientists can represent the different
types of tissue without penetrating them.
The results help fill in the scientific puzzle kicked off by Dolly's cloning, which proved that mammalian egg cells were capable of dissolving the genetic roadblocks that limit the potential of most adult cells to give rise to only a
single type of tissue — that of the organ from which they hail — whereas embryonic stem cells have the potential to become virtually any kind of body tissue.
Because different
types of tissue absorb emissions from the nanotubes differently, the scanner took readings from many locations to triangulate the tumor's exact location, as confirmed by later MRI scans.
A team of scientists from Singapore and France has revealed the underlying mechanism for the formation and growth of a
fundamental type of tissue — epithelial tubes.
It's a mystery,» he said, suggesting that it could mean stem cells thought to be committed to a particular lineage may be capable of becoming other
types of tissue entirely.
The researchers have tested the probe with many
types of tissue samples, but because it is currently designed for forward view mode, the primary applications of the probe would likely include skin, brain or head and neck surgery.
Pluripotent cells can become any of the cell types usually found in the body — although there are certain
special types of tissue, such as placenta, that they can't form.
The team hopes to apply GLIM technology to human fertility research and treatment, as well as a range of different
types of tissue research.
And then I think for the heart you obviously have a three - dimensional structure that's very, very important to the beating of the heart, and so you might need to put these into certain matrices or other
types of tissues so that those cells would engraft and stay there for the lifetime of that human.
In these breeds, chondrodystrophy predisposes the discs to being prematurely converted to an
abnormal type of tissue, whose consistency is unsuitable for the discs» function.
The two newly reported cell lines developed into several
types of tissue in culture dishes, including heart and brain, and when injected into mice generated teratomas (tumors made of the three embryonic tissue types).
To identify the molecular mechanisms of neural stem cell plasticity in adult zebrafish brain after
various types of tissue damage or physiological stimulations
Inflammation refers to irritation, perhaps swelling and even damage, to one or
more types of tissues in the body.
However, in some studies with laboratory mice, Feinberg had observed that these epigenetic tags varied considerably among the mice even when comparing the
same type of tissue in animals that have been living in the exact same conditions.
An engaging interactive notebook activity to help students learn the structure & function of the four
main types of tissue: epithelial, muscular, connective, and nervous.
«It appears to commit the stem cell to the creation of a
certain type of tissue, in this case bone,» says Cohen.
A defining property of all stem cells is that when they divide into two new cells, they can form both stem cells and differentiated cells (cells on their way to becoming a
specific type of tissue).
SOFTWARE used to keep bugs out of Microsoft Windows programs has begun shedding light on one of the big questions in modern science: how stem cells decide
what type of tissue to become.
The technique is similar to what has already been used to repair
other types of tissue, including cartilage, but had never been tried on bone.
