But you can't lose sight of how «excitable» this system is (I'm a neurophysiologist, and excitability — decision - making episodes of positive feedback usually called impulses or action potentials — are what make nerve and muscle so different from
most other cell types).
Culturing pluripotent stem cells, including embryonic stem cells, is much more complicated and expensive than culturing
most other cell types.

cells.
Also, researchers could carefully select which blood
types to culture with each batch of stem
cells, creating stockpiles of needed blood products for people with extremely rare blood
types whose blood
cell makeup makes it challenging to find good blood matches for transfusions because they would reject
most other types of blood.

types of
cells, but are used
most extensively by the nervous system for communication between neurons and to transmit information from neurons to
other body tissues such as muscles and glands.

type of white blood
cell — damaging the lungs and
other organs.
In neurons of DIXDC1 mutant mice (center) the dendrites — neural antennae that receive input from
other brain
cells — have fewer of the dendritic spines (white with red arrows)-- the receiving half of
most synaptic inputs — compared to dendrites in wild

IL - 17 attracted
other immune
cells called neutrophils — the
most abundant
type of white blood
cell — to the conjunctiva and induced the release of anti-microbial proteins into the tears.
Though
most of these proteins are present in multiple root
cell types, the researchers found, their statistical models and experiments in living plants suggest the combined effect is to activate the Short - root master switch in some
cells but not
others.
WHEN DISCUSSING neurotransmitters,
most people think of the classical neurotransmitters, such as dopamine and serotonin — the primary chemical messengers used by neurons to communicate with one another and with
other types of
cells.
While stem
cells —
cells that have the potential to differentiate into
other types of
cells — exist in adult humans, the
most useful stem
cells are those found in embryos, which are pluripotent, capable of becoming nearly any
cell in the body.
Previous in vitro studies conducted by researchers in
other countries showed that this molecule was able to reduce the multiplication and increase the mortality of
cells from melanoma, the
most aggressive
type of skin cancer, as well as breast cancer and neuroblastoma, a tumor that typically affects patients aged 15 or younger.
So to be able to make the
most efficient use of the sunlight, one of the possibilities is to build tandem -
type structures, in
other words, to fit the
cells manufactured with different polymers one on top of the
other,» explained Etxebarria.
In contrast with
most other reviews, it covers all major corneal
cell types in a comprehensive way, showing similarities and differences in the healing process and the usage of stem
cells for therapy.
Scientists at the University of Cambridge have for the first time shown that it is possible to derive from a human embryo so - called «naïve» pluripotent stem
cells — one of the
most flexible
types of stem
cell, which can develop into all human tissue
other than the placenta.
Although these processes are affected by many different
cell types within the tumour stroma, macrophages and
other myeloid - derived
cells are among the
most important players.
After the chemotherapy drug has eliminated enough of the
most prolific cancer
cell types, the
other cells that have survived are resistant to the drug and now have less competition for space and nutrients.
«The ability to direct a gene to a specific
cell type and prevent expression in
other cell types is a powerful new tool that allows us to bypass one of the
most troubling safety concerns facing gene therapy,» said Michael Parmacek, MD, assistant professor of medicine at the University of Chicago and director of the study.
Telomere shortening occurs in human
cells because the enzyme telomerase that adds DNA to the telomere is only active in few
cell types, namely stem
cells, and is turned off in
most other human
cells.
The female sifaka, though, show how some animals can chance on trichromacy even if
most of the
other members are dichromats, meaning they have only two
types of cone
cells.
In the Drosophila testis, however, the whole system has been laid out, and stem
cells can be readily identified — a major hurdle for
most other types of stem
cells.
The
most potent peptide, MA5, could bind to adenocarcinoma
cells, which make up 95 percent of all colon cancers, 150 times more strongly than
other cell types and be transferred inside
cells within 2 hours.
More specifically, the Warburg effect describes the reality that cancer
cells break down sugars more rapidly than
most other types of
cells.

other types of skin cancers are more prevalent, squamous
cell carcinoma is the
most common form of sun - induced cancer in cats and dogs.
