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.
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.
Overton studied the elaborate structures on the surfaces of cells in order to understand how single cells established and maintained connections with their partners as they matured to form
different types of tissues in the developing embryo.
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.
«There are other vertebrates, such as zebrafish, bichir and axolotl, which can regenerate many
more different types of tissues, including limbs or appendages.
But now, in turn, organ - on - a-chip research has helped advance tissue engineering's original goal, with the closely controlled microenvironments of the chips yielding important insights into the forces that drive cells to
become different types of tissue and assemble themselves into organs.
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.
Cells in the early embryo receive biological signals that direct them to contribute to
different types of tissue, and in different places.
Singer and his colleagues tested the idea using two
different types of tissue: pork loin and beef liver.
The team tested two
different types of tissue: a pork loin and beef liver.
During a segment on Yamanaka's research, one of these animations is particularly useful in explaining how chromatin regulation of gene expression is different in
different types of tissues.
Mammary gland tumors can be either malignant (cancerous) or benign (non-cancerous) and arise from
the different types of tissues (epithelial or glandular tissues, and mesenchymal or connective tissues) in the mammary gland.
